Chapter 1 - Overview
This Technical Catalog describes the main electrical, mechanical andenvironmental features of the ACS 1000 – ABB’s contribution to new solu-tions of medium-voltage AC drives. In addition, the Catalog looks at thevarious options available for the drive and offers advice on selecting amotor and drive combination. It also provides useful installation tips.
The ACS 1000 is a standard, medium-voltage AC drive, rated from 315 to5000 kW (400 to 6700 hp) for motor voltages of 2.3, 3.3 and 4.0 kV.
The drive has been designed as a standard product rather than an engi-neered drive. It is, therefore, a core product of ABB, forming part of thecompany’s ACS family. As such, the drive uses standard components,software tools and design principles as employed in the low voltage ACSrange. This vastly increases the reliability of the drive and offers users aconsistent addition to the extensive ACS product range.
As a standard solution the ACS 1000 has many of the benefits associatedwith engineered drives already included. This meets the most commonsystem specifications with minimal engineering. In addition, because thedrive is pre-engineered, shorter delivery times to end-users are possible.
About 85% of all medium-voltage drives are applied in standard applica-tions such as fans, pumps, conveyors and compressors, where thecustomized engineering content is minimal. The ACS 1000 is ideally suit-able for retrofit applications, where only a small portion of the world’smotors are fitted with drives.
Industries, which can benefit from this approach, include oil and gas,mining, water, pulp & paper, cement and power generation.
Two main technology features distinguish the ACS 1000 from other typeson the market:
• The motor control platform is based on Direct Torque Control (DTC)which achieves the ultimate torque and speed performance.
DTC allows the speed of any standard squirrel cage induction motorto be controlled without the need for expensive and fragile encodersor tachogenerator feedback devices.
1.1 Introduction
1.2 The Standard Solution
1.3 Key Technology
ACS 1000 Technical Catalog 7
Chapter 1 - Overview
• For the first time in any AC drive, a new power semiconductor switch-ing device is utilized. Known as IGCT (Integrated Gate CommutatedThyristor), the device provides an intrinsically less complex, more ef-ficient and reliable drive. This is achieved by fast switching and inher-ently low losses which mean less cooling equipment is needed.
IGCTs do not require snubber circuits and allow power bridge imple-mentation with fewer power devices than conventional medium-voltage drives. While reliability is improved, the physical size of theACS 1000 is compact.
The technology described above brings many more practical benefits tothe ACS 1000, as described within this Catalog.
For instance, the use of IGCTs together with active feedback control bymeans of an LC filter results in a sinusoidal output voltage. This provesuseful in retrofit applications, as the drive is compatible with existingsquirrel cage motors without the need to derate it. There are no unduevoltage rises stressing the motor insulation and voltage reflections areeliminated on long cable runs.
Furthermore, DTC avoids any torque pulsations, which can be damagingto loads and their associated mechanical connections.
The ACS 1000 is available for use with a separately mounted input isola-tion transformer (standard) or alternatively with an integrated dry-typetransformer. This provides installation flexibility and allows for the use of oilfilled transformers which are typically mounted outdoors.
The ACS 1000 meets all common standards including IEC and EN. Inorder to meet the requirements of the North American market, theACS 1000 is also UL and Canadian UL listed. In addition, ABB has under-taken much development work to ensure that the converter adequatelymeets the requirements of the world’s harmonics standards, such asIEEE 519-1992.
For details please refer to Appendix D - Applicable Codes and Standards.
The ACS 1000 features a selection of pre-programmed and standardizedapplication macros for the configuration of inputs, outputs, signalprocessing and other parameters.
1.4 Technical Benefits
8 ACS 1000 Technical Catalog
Chapter 1 - Overview
The ACS 1000 is available as air-cooled and water-cooled types. The air-cooled ACS 1000 covers rated power outputs from 400 HP to 2250 HP(315 kW to 1600 kW). For higher power output ratings ranging from2500 HP to 6700 HP (1800 kW to 5000 kW), the converters are water-cooled.
The ACS 1000 converter is available for 3 different medium voltage levels.These are the standard motor voltages of 2.3 kV, 3.3 kV and 4.0 kV. Forinformation on solutions for retrofit applications with motor voltages of upto 7.2 kV please contact your ABB representative.
The table below provides an overview of the rated output power range,covering air and water-cooled converters for all three medium voltagelevels.
For further details, refer to Chapter 8 - Selecting the Drive System.
Table 1-1 Standard power ranges for ACS 1000 converters
** The power ratings apply to typical 4 pole motors. For those motors thefrequency converter has a built-in overloadability of 10%. When selectingthe frequency converter it should be observed that the rated current of theACS 1000 must be higher than or equal to the rated motor current in orderto achieve the rated motor power given in the table.
Note: For air-cooled units (with enclosure class IP21) the load capacity(current and power) depends on the altitude and the ambient temperatureat the installation site. In case of water-cooled units the load capacitydepends on the cooling water temperature at the installation site. Fordetails on the derating factors, see Appendix B - Technical Data.

Chapter 2 - Main Features
ABB researched and designed the Integrated Gate Commutated Thyristor(IGCT) specifically for the medium voltage market. IGCTs provide highspeed switching like IGBTs (Insulated Gate Bipolar Transistors) and at thesame time provide high voltage blocking and low loss conduction likeGTOs (Gate Turn-Off Thyristors). The result is a fast, low loss device thatcan be used at medium voltage levels without resorting to series topolo-gies. It transcends both of the older technologies from which it evolved.IGCTs also provide other benefits:
• Freewheeling diode is integrated into the same package
• Snubber circuits are not required
• Gating circuitry is packaged with the power device
• High reliability (low total parts count)
• High power density (combination of low total parts count and lowpower losses)
• Self-protecting against destructive failures.
All these features combined provide a medium voltage power switchingdevice with the best combination of performance, reliability, efficiency, andspace effectiveness available in the market today.
The ACS 1000 features a fuseless protected medium voltage drive.
The patented design uses the new power semiconductor switching device,IGCT, for circuit protection.
The IGCT, which is placed between the DC-link and the rectifier, can,unlike conventional fuses, directly isolate the inverter of the drive systemfrom the power supply side. This is achieved within 25 microseconds,which is 1000 times faster than the operational performance of fuses.
Using the IGCT as an integrated protection device leads to a lower partscount within the drive system making the ACS 1000 a drive withoutstanding reliability.
The reason why IGCTs are capable of performing a protection function,unlike other power semiconductor devices, lies in their low onstate lossesand their ability to turn off at high speed at medium voltage levels.

Chapter 2 - Main Features
Direct Torque Control (DTC) is a unique motor control method for ACdrives. The inverter switching is directly controlled according to the motorcore variables flux and torque.
The measured motor current and DC-link voltage are inputs to an adaptivemotor model which produces exact actual values of torque and flux every25 microseconds. Motor torque and flux comparators compare actualvalues to the reference values produced by the torque and flux referencecontrollers. Depending on the outputs from the hysteresis controllers, thepulse selector directly determines the optimum inverter switch positions.

Chapter 2 - Main Features
How does DTC differfrom PWM Flux Vector
Drives?
In DTC, each switching instance is determined separately based on thevalues of flux and torque, rather than switching in a predetermined patternas in conventional PWM flux vector drives.
Table 2-1 DTC versus PWM Flux Vector controlled drives
For more information on DTC, please refer to the Technical GuideNo. 1 Direct Torque Control (3AFY 58056685 R0025).
The ACS 1000 features a 12-pulse diode rectifier input stage. This isadequate for most networks and normally meets the harmonic require-ments demanded by standards such as IEEE 519.
For networks that are more demanding, the ACS 1000 can be suppliedoptionally with a 24-pulse configuration for water-cooled and for air-cooledtypes.
As a standard the ACS 1000 is equipped with a low pass LC sine filter inits output stage. Current feedback is used to actively control filter opera-tion. The low pass frequency is designed to be well below the lowestswitching frequency used by the inverter output stage. This greatlyenhances the purity of both the voltage and current waveforms applied tothe motor. This in turn provides many important benefits:
• Harmonic heating is virtually eliminated. The drive may be used tosupply standard medium voltage motors (existing or new) without ap-plying thermal derating factors.

Chapter 2 - Main Features
• Voltage reflection and the associated occurrence of voltage doublingat the motor input terminals is no longer an issue (the causal high fre-quency content does not exist). Therefore, any standard medium volt-age winding insulation system (existing or new) is compatible with theACS 1000.
• The maximum length of the motor cables is not limited by theACS 1000 (normal voltage drop restrictions as found in any electricalinstallation still apply).
• Motor bearing failures attributable to capacitively coupled high fre-quency current are no longer a problem (the causal high frequencycommon mode voltage is eliminated).
• Motor insulation is not subject to the common mode voltage typical forother drive topologies.
Figure 2-2 and Figure 2-3 show the elementary circuit diagram of the 12-pulse and the 24-pulse versions of the ACS 1000.
The 3-phase AC line voltage is supplied to the rectifier bridges through the3-winding converter transformer. In order to obtain 12 or 24-pulse rectifi-cation, appropriate phase shift is necessary between the secondary wind-ings of the transformer.
The two fuseless rectifier bridges in the 12-pulse scheme (Figure 2-2) areconnected in series, such that the DC voltages are added up. Therefore,the full DC bus current flows through both bridges. In the 24-pulsescheme, 2 such bridge arrangements are connected in parallel as shownin Figure 2-3.

Figure 2-3 Elementary diagram - ACS 1000, 24-pulse version
Each leg of the 3-phase inverter bridge consists of a combination of 2IGCTs for 3-level switching operation: with the IGCTs the output isswitched between positive DC voltage, neutral point (NP) and negative DCvoltage. Hence both the output voltage and the frequency can becontrolled continuously from zero to maximum, using Direct TorqueControl.
At the converter output a LC filter is used for reducing the harmoniccontent of the output voltage. With this filter, the voltage waveform appliedto the motor is nearly sinusoidal (see Figure 2-4). Therefore, standardmotors can be used at their nominal ratings. The filter also eliminates allhigh dv/dt effects and thus voltage reflections in the motor cables andstresses to the motor insulation are totally eliminated.

Chapter 3 - Hardware Description
The riveted and folded cabinet construction of the ACS 1000 ensures anextremely strong yet flexible and self-supporting framework which avoidsthe need for additional skeletal support. Compared with traditional boltedframes the cabinet provides extremely effective protection against electro-magnetic emissions.
The design fulfils the requirements of international standards likeUL 347A. For details please refer to Appendix D - Applicable Codes andStandards.
Electromagnetic Compatibility (EMC) has been achieved by applying acabinet design consisting of folded, galvanized sheet metal plates andminimizing the spacing between the rivets. The cabinet’s inside walls arenot painted, because paint tends to reduce the effectiveness of metallicbonding which is paramount to successful EMC.
Accordingly, only the front of the ACS 1000 cabinet is painted while allother walls are galvanized. However, the cabinet can be ordered optionallywith the whole of the outside painted.
EMC performance is further enhanced by the use of metal cable channels.
3.2.1 Air-cooled Type
The air-cooled type of the ACS 1000 is designed with inverter stacks,output filter and DC-link capacitor in one section (see Figure 3-1). Thissection experiences maximum air flow which is advantageous for thetemperature sensitive capacitors. The construction of the inverter stacksallows easy exchange of IGCTs by means of a specially designed toolwhich is part of the supply.
The middle section accommodates cooling fan, rectifier stack, protectionIGCTs and filter reactor. The construction is such that the fan can beexchanged easily.
The air intake is provided with an air filter in order to prevent dust andparticles from entering into the converter. The air filter can be replacedfrom outside while the drive system is in operation.

24-pulse Version The cabinet layout of the water-cooled 24-pulse version of the ACS 1000is identical to the 12-pulse version, with the exception that there is an addi-tional cabinet on the left hand side of the control section, containing theextra rectifier stacks for 24-pulse operation.
3.2.3 Power Terminals
The leftmost section (Figure 3-1 and Figure 3-2) contains the swing framewith the control equipment (see Section Control Equipment, page 21).Behind this swing frame and a protective separation door is the drive’spower terminal section with busbars for mains and motor cables. Toprovide optimum access to the power terminals, the swing frame can beopened more than 120°.
Please refer to Appendix A - Installation Guidelines for further details oncable entry and connection.

All doors are hinged and locked using carriage key locks.
The doors of the power sections of the drive are electromechanically inter-locked with the safety grounding switch and with the main circuit breakerupstream of the converter transformer. This interlock system ensures thatnone of the power cabinets can be opened until the main source of poweris disconnected, the DC-link capacitors are discharged and the safetygrounding switch is closed. Additionally the same interlock system insuresthat power cannot be initialized to the drive unless the doors are closedand the safety grounding switch has been opened.

Chapter 3 - Hardware Description
The doors of the control section and of the cooling section (water-cooledtype) are not linked to the interlocking system. They can be opened at anytime. The high voltage busbar section is located behind the control swingframe and separated from the control section by a bolted protective shield.
The power section doors of all additional cabinets (e.g. additional rectifiercabinet, braking chopper cabinet) are monitored by separate doorswitches since they are not included in the electromechanical interlocksystem. These door monitoring switches are wired to the drive’s trippingloop. If any of the doors are opened during operation, the MCB will betripped immediately.
The standard ACS 1000 cabinet is rated IP21 for air-cooled and IP 31 forwater-cooled types. Higher IP ratings are available as options. SeeChapter 7 - Options for further details.
The cabinets are fitted with lifting lugs as standard.
The standard color is RAL 7035 (light grey). Other colors are available onrequest.
The ACS 1000 cabinet system provides the flexibility to add furthersections to the converter at any time. Sections can be added in width of600, 800 and 1000 mm (24, 32 and 39 inches).

Using the CDP 312 panel it is possible to
• enter start-up data into the drive
• set a reference signal and give Start, Stop and Direction commands
• display actual values (three values can be read simultaneously)
• display and adjust parameters
• display information on the most recent forty fault events.
The standard I/O-boards offer a number of pre-programmed analog anddigital I/Os which are sufficient for most applications. For a wider range ofsignal interfaces optional I/O-boards can be ordered for water and air-cooled ACS 1000 to provide extended protection for transformer andmotor, external cooling equipment (e.g. fans, chillers), on-linesynchronization logic and other customer requirements.
The air-cooled ACS 1000 is equipped with two I/O-boards (IOEC1 andIOEC2) as a standard with the option of two additional I/O-boards (IOEC3and IOEC4). The water-cooled ACS 1000 is equipped with three I/O-boards (IOEC1, IOEC2, IOEC3) with the option of one aditional I/O-board(IOEC4).
All I/O-boards are identical in design with the same number of I/Os. Theanalog and digital I/Os are floating and galvanically isolated with ratingsas indicated in Table 4-1.
While the function of digital and analog inputs are fixed and cannot bealtered, the signals allocated to digital and analog outputs can be changedby setting the corresponding parameters accordingly.

Chapter 5 - Parameters and Application Macros
Parameters allow the user specific configuration of the ACS 1000. Theycan be set using the CDP 312 control panel.
The application macros consist of pre-programmed parameter sets thatare adapted for a specific application. They offer pre-set signal interfacesfor opening/closing the main circuit breaker, starting/stopping the drivesystem and setting reference values.
Depending on the process, the appropriate macro can be selected, thusenabling a quick and easy start-up of the ACS 1000.
Using an application macro has the advantage that the number ofindividual parameters to be set during start-up is minimized. All para-meters have factory-set default values. Leaving them unchanged, a goodsystem performance is achieved in typical situations. These default valuescan be left unchanged or they can be set individually according to theneeds of the customer.
The ACS 1000 can be operated with one of the following standard macros:
• Factory
• Speed Control
• Hand/Auto
• PID Control
• Torque Control
• Sequential Control
• Master/Follower
• User 1
• User 2
Factory The Factory Macro is the default-set macro. It covers most of the commonapplications, such as:
• Pump, fan and other industrial processes with a square torque char-acteristic
• Conveyors and other industrial drives requiring constant torque.
5.1 Overview
5.2 Suitable Applications for Different Macros
ACS 1000 Technical Catalog 33
Chapter 5 - Parameters and Application Macros
Speed Control The Speed Control Macro is essentially the same as the Factory Macro.The only difference to the Factory Macro is that a loading of the SpeedControl Macro will not affect the currently set motor control parameters(when loading the Factory Macro all parameters will be reset to theirdefault value).
Hand/Auto The Hand/Auto Macro is suitable for applications where the speed has tobe controlled automatically by a process control system and manually byan external control panel. The active control location is selected via adigital input.
The macro is also recommended when the drive has to be controlled fromtwo external control stations. The active control station for starting /stop-ping and setting of the reference value is selected via a digital input.
PID Control The PID Macro is intended for the use with closed loop control systemssuch as pressure control, level control and flow control. For example:
• Booster pumps of municipal water supply systems
• Booster pumps of district heating systems
• Automatic level control of water reservoirs
• Speed control of different types of material handling systems wherethe material flow has to be regulated.
The PID-controller is incorporated into the ACS 1000 software. It is acti-vated by selecting the PID Macro.A process reference value is set via an analog input or by using the controlpanel of the ACS 1000. The actual process value is connected to a dedi-cated analog input.The internal PID-controller of the ACS 1000 eliminates the need of a sepa-rate PID-controller (no additional installation and wiring required).

Chapter 5 - Parameters and Application Macros
Torque Control The macro is intended for processes requiring torque control, e.g. mixersand slave drives. The torque reference comes from a process automationsystem or a control panel.
Sequential Control The Sequential Control Macro is aimed for processes where differentconstant speed settings and/or different acceleration/deceleration rampsare required in addition to an adjustable speed reference value. Thedifferent settings can be selected automatically by a process controlsystem or they can be activated manually by selector switches which areconnected to the corresponding digital inputs.
Master/Follower The Master/Follower Macro is designed for applications with severalACS 1000 where the motor shafts are coupled to each other by gearing,chain, belt etc. Thanks to the Master/Follower macro the load can beevenly distributed between the drives or depending on the process atsome other ratio.
User 1 / User 2 The User Macro 1 and 2 allows to save a complete set of customizedparameters and to recall it at a later instant or to download it to anotherACS 1000.

Chapter 6 - Standard Functions
The ACS 1000 is configured and customized by means of applicationparameters. These parameters can be altered by the user, either bymeans of the integrated CDP 312 control panel or by using a PC and theDriveWindow software package, as described in Chapter 7 - Options.
Control and monitoring functions of the ACS 1000 can be activated bysetting parameters one by one or by invoking an Application Macro (seeChapter 5 - Parameters and Application Macros) which is optimized for aparticular application. Therefore some of the functions described in thischapter will be configured automatically if an application macro isselected.
This chapter provides information about the standard control, monitoringand protection functions for the ACS 1000. A description of the basic I/Odevices and the application macros of the ACS 1000 can be found inChapter 4 - User Interfaces and Chapter 5 - Parameters and ApplicationMacros.
6.2.1 General Functions
Motor ID Calculation Based on the nameplate data all ACS 1000 internal motor controlparameters will be automatically calculated. This procedure is usuallyperformed once during commissioning. However, the procedure can berepeated whenever required (e.g. when the ACS 1000 will be hooked upto another motor).
Full Torque at ZeroSpeed
A motor fed by the ACS 1000 can develop short-term motor nominaltorque at start-up without any pulse encoder or tachogenerator feedback.This feature is essential for constant torque applications. However, ifpermanent operation at zero speed is required, a pulse encoder has to beused.
Enhanced Flying Start This feature allows a rotating motor (e.g. a turbo-pump or a fan) to betaken over by the ACS 1000. By means of the flying start function thefrequency of the motor is detected and the motor is started-up again by theACS 1000.
6.1 General
6.2 Standard Control Functions
ACS 1000 Technical Catalog 39
Chapter 6 - Standard Functions
Flux Optimization Flux optimization of the ACS 1000 reduces the total energy consumptionand motor noise level when the drive operates below the nominal load.The total efficiency (ACS 1000 and motor) can be improved by 1...10%,depending on the load torque and speed. This function is activated byparameters.
Power Loss Ride-Through
If the incoming supply voltage is cut off the ACS 1000 will continue tooperate in an active but non-torque producing mode by utilizing the kineticenergy of the rotating motor and load. The ACS 1000 will be fully active aslong as the motor rotates and generates energy to the ACS 1000. Powerloss ride through can be enabled by parameters.
Auxiliary Ride Through The auxiliary ride through function guarantees correct fault indication andproper trip sequencing, in the event that the auxiliary power source feedingthe drive is lost. The function is activated by a parameter. During ridethrough the power for the control circuits of the ACS 1000 is supplied byinternal batteries. The ride through time is limited to 1 sec.
Acceleration andDeceleration Ramps
ACS 1000 provides two user-selectable acceleration and decelerationramps. It is possible to adjust the acceleration/deceleration times(0...1800 s) and select the ramp shape. Switching between the two rampscan be controlled via a digital input.
The available ramp shape alternatives are:
Linear: Suitable for drives requiring long acceleration/deceleration whereS-curve ramping is not required.
S1: Suit. for short acc./dec. times.
S2: Suit. for medium acc./dec. times
S3: Suit. for long acc./dec. times.
S-curve ramps are ideal for conveyorscarrying fragile loads, or other applica-tions where a smooth transition isrequired when changing from onespeed to another.
Critical Speed There is a Critical Speed function available for applications where it isnecessary to avoid certain motor speeds or speed bands, for example dueto mechanical resonance problems. The ACS 1000 makes it possible toset up five different speed settings or speed bands which will be avoidedduring operation.

Chapter 6 - Standard Functions
Each critical speed setting allows theuser to define a low and a high speedlimit. If the speed reference signalrequires the ACS 1000 to operatewithin this speed range the CriticalSpeeds function will keep theACS 1000 operating at the low (orhigh) limit until the reference is out ofthe critical speed range. The motor isaccelerated/decelerated through thecritical speed band according to theacceleration or deceleration ramp.
Constant Speeds Up to 15 constant speeds can be programmed and selected by digitalinputs. If activated the external speed reference is overwritten. If theSequential Control Macro is used a standard set of parameter values isselected automatically.
Accurate SpeedControl
The static speed control error is typically +0.1% (10 % of nominal slip) ofthe motor nominal speed, which satisfies most industrial applications.
Accurate TorqueControl without Speed
Feedback
The ACS 1000 can perform precisetorque control without any speed feed-back from the motor shaft. With torquerise time less than 10 ms at 100%torque reference step compared toover 100 milliseconds in frequencyconverters using sensorless fluxvector control, the ACS 1000 isunbeatable.
By applying a torque reference insteadof a speed reference, the ACS 1000will maintain a specific motor torquevalue; the speed will be adjusted auto-matically to maintain the requiredtorque.

6.2.2 Main Circuit Breaker Control
All functions regarding the control of the main circuit breaker (opening,closing, tripping, monitoring) are included in the ACS 1000.
For detailed information see Chapter 8 - Selecting the Drive System, MainCircuit Breaker, page 63.
6.2.3 Local and Remote Control
Operation of the ACS 1000 is possible either in local or remote controlmode.
Local/remote control is selected directly on the CDP 312 control panel bypushing the LOC/REM push-button. A capital L on the display indicateslocal control:.
Remote control is indicated with a blank:
Local Control If the converter is in local control, local operation using the push-buttonson the converter front door and the CDP 312 control panel is possible. Inlocal operation mode no remote control command will be accepted.
Remote Control If remote control is selected, local operation from the push-buttons on theconverter front door and from the CDP 312 control panel is not possible.Instead all commands for closing and opening the main circuit breaker orstarting and stopping the drive are received via digital inputs from a remotecontrol station. The speed reference value is given as an analog inputsignal.
Alternatively all remote control signals can be exchanged via an optionalfieldbus interface.
Changing the control mode from local to remote and vice versa can bedisabled by setting digital input “DISABLE LOCAL” (see also Table 4-2).

ACS 1000 Technical Catalog 43
Chapter 6 - Standard Functions
Programmable AnalogOutputs
Two programmable analog outputs on each IOEC board are at the user’sdisposal.
Depending on the setting of the corresponding parameters, the analogoutput signals can represent for example:
• motor speed, process speed (scaled motor speed), output frequency,output current, motor torque, motor power, DC bus voltage, outputvoltage, application block output (process PID controller output),active reference, reference deviation (difference between thereference and the actual value of the process PID controller).
The selected analog output signals can be inverted and filtered. Theminimum signal level can be set to 0 mA, 4 mA or 10 mA.
6.2.6 Scalable Analog Inputs
Each analog input can be adapted individually to the type and range of theconnected input signal:
• signal type: voltage or current (selectable by DIP switches)
• signal inversion: if a signal is inverted, the maximum input level cor-responds to the minimum signal value and vice versa
• minimum level: 0 mA (0 V), 4 mA (2 V) or by input tuning function (ac-tual input value is read and set as minimum)
• maximum level: 20 mA (10 V) or by input tuning function (actual inputvalue is read and set as maximum)
• signal filtering time constant: adjustable between 0.01..10 s.
The offset of the analog inputs can be calibrated automatically ormanually.
6.2.7 Input Signal Source Selections and Signal Processing
Two ProgrammableControl Locations
The ACS 1000 can receive the Start/Stop/Direction commands and thereference value from the integrated control panel and the Closing/Openingcommands for the main circuit breaker from the push buttons on thecontrol section door.
Alternatively it is possible to predefine two separate external control loca-tions (EXT1 and EXT2) for these signals. The active external control loca-tion can be changed via the control panel or via a digital input.
The control panel always overrides the other control signal sources whenswitched to local mode.
Optionally, the converter can be equipped with a fieldbus adapter module,see Chapter 7 - Options.
Reference SignalProcessing
The ACS 1000 can handle a variety of speed reference schemes inaddition to the conventional analog input signal and control panel signals.
• The ACS 1000 reference can be given using two digital inputs:
44 ACS 1000 Technical Catalog
Chapter 6 - Standard Functions
one digital input increases the speed, the other decreases it. The ac-tive reference is memorized by the control software.
• The ACS 1000 can form a reference out of two analog input signalsby using mathematical functions: addition, subtraction, multiplication,minimum selection, and maximum selection.
It is possible to override the actual speed reference with predefinedconstant speeds (see Constant Speeds, page 41).
It is possible to scale the external reference so that the signal minimumand maximum values correspond to a speed other than the nominalminimum and maximum speed limits.
The ACS 1000 offers several programmable fault functions and other non-user adjustable pre-programmed protection functions.
6.3.1 Programmable Fault Functions
Motor WindingTemperature
The motor can be protected from overheating by activating the motorwinding temperature monitoring function.
The ACS 1000 standard solution offers three analog inputs for measuringand monitoring the motor winding temperature.
Values for alarm and trip levels can be set.
Motor Stall The ACS 1000 protects the motor if a stall condition is detected. The moni-toring limits for stall frequency (speed) and stall time can be set by theuser. The user can also select whether the stall function is enabled andwhether the drive responds with an alarm or a trip when a stall is detected.
The protection is activated if all the following conditions are fulfilledsimultaneuously:
1 The output frequency is below the setstall frequency.
2 The drive is in torque limit. The torquelimit level is a basic setup parameterthat sets maximum drive output torque.Although it indirectly effects operation ofthe motor stall protection, it should notbe considered a motor stall parameter.
3 The frequency and torque levels fromconditions 1 and 2 have been presentfor a period longer than the set stalltime.

Underload Loss of motor load may indicate a process malfunction. The ACS 1000provides an underload function to protect the machinery and the processin such a serious fault condition. This monitoring function checks if themotor load is above the specified load curve. 5 different load curves canbe selected by the customer.
Monitoring limits: underload curve and underload time can be chosen aswell as the drive response to the underload condition (alarm / trip indica-tion and stop the drive / no reaction).
Figure 6-2 Load curves for underload function
The protection is activated if all the following conditions are fulfilled simul-taneously:
1 The motor load is below the underload curve selected by the user(see Figure 6-2).
2 The motor load has been below the selected underload curve longerthan the time set by the user (Underload time).
Overspeed The motor speed as determined by DTC is monitored. If the motor speedexceeds the maximum permitted motor speed (user adjustable) a trip isinitiated. In addition, an input for connection of an external motor over-speed trip is available. A converter trip is also initiated, if the externalmotor overspeed trip is activated (signal active when low).
Undervoltage In order to detect a loss of the mains power supply, the positive andnegative DC link voltage levels are monitored. If these voltage levels dropbelow 70% of their nominal levels an undervoltage alarm is initiated andpower loss ride through is activated (provided it is selected). If the DC linkvoltage levels drop below 65% of their nominal values an undervoltage tripis initiated.

6.3.2 Pre-programmed Protection Functions
Motor Phase Loss The phase loss function monitors the status of the motor cableconnections. The function is useful especially during motor starting:the ACS 1000 detects if any of the motor phases are not connected andrefuses to start.
The phase loss function also monitors the motor connection status duringnormal operation. The motor operating frequency must be above aminimum level in order for this feature to function. Should a motor phaseloss be detected a trip is initiated.
Motor Overload The 3-phase RMS value of the motor current is monitored and comparedwith three adjustable thresholds. A pickup delay for each threshold canalso be set. In case an overload is detected an alarm message will bedisplayed and the converter will be shut down.
Overvoltage The levels of the positive and negative DC link voltage are monitored todetect whether an improper overvoltage condition develops. If thesevoltage levels rise above 130% of their nominal levels an overvoltage tripis initiated. On rare occasions, a combination of conditions can result inthe motor entering a self excitation mode that can cause the DC linkvoltage to continue to rise, despite the fact that a trip has been initiated. Ifthis condition occurs and if the DC link voltage levels rise above 135% oftheir nominal levels, a second overvoltage trip is initiated that causes theinner 6 IGCT’s to be gated simultaneously such, that the motor windingsare effectively shunted together. This eliminates the self excitation voltagethat is causing the DC link voltage levels to rise. To provide ultimatereliability the second overvoltage trip is implemented both in software andredundantly in hardware (140%).
Short Circuit in theRectifier Bridge
A short circuit in the rectifier bridge is detected by monitoring the DC linkvoltage. If a short circuit is detected, a trip is initiated and the drive isdisconnected from the supply voltage.
Charging Fault The intermediate DC link voltage is monitored while the DC link is ener-gized. If the voltage does not reach a certain level after a preset time, atrip is initiated.
Supply Phase Loss If the voltage ripple in the intermediate DC link rises above a preset level,a trip is initiated because a supply phase may be lost.
Overcurrent The overcurrent trip limit for the ACS 1000 is 2.2 x IN RMS of the nominalinverter current. If this level is exceeded, a trip is initiated.
Inverter Temperature In order to insure that the inverter section does not exceed the tempera-ture limits, the current is monitored and limited to the maximum permittedlevel.
Cooling Circuit The operating condition of the cooling circuit is monitored. If any of themonitored signals such as water temperature, water pressure or conduc-tivity exceed a preset limit, a trip is initiated. In addition, the status of the
ACS 1000 Technical Catalog 47
Chapter 6 - Standard Functions
cooling water pumps, the water level in the expansion vessel and theauxiliary fan are monitored.
Short Circuit of theInverter
The inverter is monitored to ensure that a short circuit condition does notexist. If a short circuit is detected a trip is initiated.
Ground Fault The current in the output filter ground leg is monitored and compared withtwo thresholds. The first threshold is set to a fixed percentage of the peakvalue of the nominal inverter current. The second threshold is adjustableand compared with the RMS value of the ground current. If the groundcurrent exceeds one of the thresholds a corresponding alarm messagewill be displayed and the drive will be shut down.
Ground faults will be detected in the area between the ACS 1000 trans-former secondary side and the motor.
Operating System The operating system of the microprocessor board monitores differentfunctions within the control software and will initiate a trip if a malfunctionis detected. Such faults are displayed as “Control SW fault”. Should oneof these faults be detected during operation, the drive should be restarted.
Communication Fault Except for the measurement boards all communication links are realizedby DDCS (Distributed Drive Control System). If one of these links fails atrip is initiated.
Measurement Loss On the ADCVI board (analog digital conversion for voltage and current)analog signals are converted into digital signals. The digital signals arethen transmitted via PPCC (fiber-optic bus system) to the interface boardwhich is the main interface to the converter control system.
In order to guarantee proper operation of the protection functions includedin the converter, the status of the communication is monitored on the inter-face board. If a fault is detected a trip is initiated.
Battery Test The back-up batteries are checked periodically by applying a known loadand by measuring the resulting voltage drop. If the charge of the batteriesis deficient, a fault message is displayed and either a normal stop or analarm is initiated.
ID-Run Fault During commissioning an identification run has to be carried out. Thenominal data for identification of the system parameters has to be entered.If incorrect values are used and therefore the system parameters cannotbe determined, a trip is initiated. In this case the identification run has tobe repeated after the correct data has been entered.

Process Stop A process stop button or relay can be connected to a pre-defined input ofthe ACS 1000. The actual process stop input must be closed duringnormal operation. If the digital input opens, the drive control initiates a stopcommand. The stop mode (ramp stop, stop at torque limit, or coast stop)can be selected by a parameter. When the drive is stopped the main circuitbreaker is opened.
External EmergencyOff
The normally closed (NC) contacts of external emergency-off buttons canbe wired into the tripping loop.
For further details see Chapter 4 - User Interfaces.
Automatic Restart The ACS 1000 can automatically reset itself after an undervoltage hasoccurred. This function is activated by two parameters one to enable theautomatic restart function and one to select the undervoltage waiting time(adjustable between 0 and 600 s).
If the automatic restart feature is activated and an undervoltage isdetected in the DC-link, the waiting time is started. If the voltage recoverswithin the selected time, the fault will be reset automatically and theconverter resumes normal operation. If the waiting time has elapsed andthe voltage has not recovered the converter is tripped and the MCB isopened.
Monitoring of LimitValues
The values of several user selectable signals can be monitored for adjust-able low and high limits.
Adjustable limits can be set for: two speed values, a current value, twotorque values, two reference values and two actual values of the PIDcontroller. The digital status of the active limit appears on the control paneldisplay and can also be allocated to digital output.
ACS 1000 Information The software version and the serial number of the ACS 1000 can bedisplayed on the CDP 312 control panel.

Extended GroundingBusbar
The standard grounding busbar which is located in the power cabletermination section of the ACS 1000 can be an extended throughout themedium voltage sections of the ACS 1000.
Input Bridges The following input rectifier bridges are available:
• 12-pulse diode rectifier (standard)
This type is sufficient for most network conditions to fulfill the networkharmonic requirements according to IEEE 519-1992.
It is the ideal solution for a small converter footprint and if an outdoortransformer can be used.
• 24-pulse diode rectifier with integrated or external transformerconfiguration
This type is recommended if superior network behavior is required.
The 24-pulse diode rectifier is applicable if outdoor transformers arenot required. In this case there is no need for an oil pit and no addi-tional cabling between transformer and converter is needed whichcan substantially reduce construction and installation costs.

Line UnbalanceProtection Relay
A signal from a line unbalance protection relay can be monitored by wiringit into the tripping loop of the ACS 1000. If the signal is low the main circuitbreaker is tripped immediately.
Common Mode Choke This option is needed if the cable length between the converter trans-former and the ACS 1000 exceeds the following limits:
• 30 m (98 ft) for ACS 1000, 12-pulse versions and
• 20 m (66 ft) for ACS 1000, 24-pulse versions.
If the cables are longer than the limits below, the ABB representativeshould be contacted:
• 200 m (656 ft) for ACS 1000, 12-pulse versions and
• 150 m (492 ft) for ACS 1000, 24-pulse versions.
The DC link common mode choke functions like a transformer. Togetherwith the common mode damping resistor it provides damping of thecommon mode voltages and limits the common mode currents experi-enced by the main power transformer and transformer secondary cables.

Ex-Zone SignalInterface for Motor
Measurements (ZenerBarriers)
For motor installations in hazardous areas (Ex-Zone) all interface signalsfrom the motor have to be connected to Zener Barriers mounted in theconverter. This applies to the winding temperature and bearingtemperature measurements as well as to all digital signals e.g. externalmotor protection alarm and trip and external overspeed trip.
If this option is required, contact your ABB representative.
Pulse EncoderInterface Module
The Module allows a pulse encoder to be connected to the ACS 1000. Apulse encoder is advantageous in applications where the flying startfunction is used. The actual frequency of a rotating motor can be detectedfaster and rapid start-up by the converter can be achieved. It is alsorecommended if a highly accurate read-out of the speed is required.
Another application for a pulse encoder would be for motors running atspeeds below 5 Hz for longer periods.
The requirements for a pulse encoder are as follows:
• Supply voltage 12 VDC or 24 VDC (supplied by the module)
• Single ended or differential connection can be used
• Available signal channels: A, A inverted, B (90° electr. phase shift toA), B inverted (Z (zero channel), Z inverted - optional)

Increased OutputFrequency
The ACS 1000 can be ordered with an increased output frequency of82.5 Hz as a maximum. This option requires an optimized sine filterconfiguration.
Braking Chopper Effective motor braking and short deceleration times can be achieved byusing resistor braking. For resistor braking, the ACS 1000 converter mustbe equipped with a braking chopper and a braking resistor.
Braking choppers are available for all ACS 1000 types. The choppers canbe ordered factory-installed or as add-on kits.
The operation of the braking chopper is controlled by the ACS 1000control system. The braking chopper hardware is located in an additionalcabinet.
The input currents of the braking chopper are monitored for overcurrentand unbalance in order to detect any defective component in the circuit. Incase a short circuit or an unsymmetry in the braking chopper is detecteda converter trip is initiated.
Braking chopper and braking resistors are each monitored forovertemperature by means of thermal models. Alarm and trip levels aredetermined and set during commissioning.
For more information about braking chopper and braking resistor, see theresistor specification or contact your ABB representative.
Braking Resistor The braking resistor has to be specified individually for eachproject by ABB Industrie AG. For further information contact your ABBrepresentative.

Chapter 8 - Selecting the Drive System
The excellent performance of the ACS 1000 makes it suitable for mostvariable speed drive applications.
In order to dimension and configure an ACS 1000 drive system, the drivenload has to be clearly specified and an appropriate motor must beselected. The driven load together with the selected motor basicallydetermines the size of the ACS 1000 as well as the size of the requiredconverter input transformer.
8.2.1 Main Circuit Breaker Control
The Main Circuit Breaker (MCB) must be controlled exclusively by theACS 1000. This means that a closing request or command is sent from acustomer’s local or remote control station to the ACS 1000. The actualclosing command is then released from the converter to the MCB.
The closing command from the converter to the MCB (duration can be pre-set) can be a continuous signal or a single pulse, which is reset as soonas the status feedback MCB IS CLOSED has been received from theswitchgear. If this status feedback has not arrived after a pre-set time, theclosing command is reset and a trip of the MCB is initiated.
The MCB is opened by :
• an MCB OPEN command, either given from the push button on theACS 1000 or from a remote control station via digital inputs orthrough a fieldbus adapter
• the hardwired tripping loop (see Tripping Loop, page 64).
The opening command from the converter to the MCB - pulse or steadystate signal - is reset as soon as the status feedback MCB IS OPEN hasbeen received. If the feedback signal has not arrived after a preset timethe command MCB ORDER TRIP is initiated to open the MCB.
The MCB ORDER TRIP is a steady state true signal. When in low statusit directly opens the MCB.
MCB Control Fault All opening and closing commands to the MCB are monitored for time-outAn alarm or fault message comes up on the display of the CDP 312 controlpanel if there is something wrong in connection with the control of theMCB.

8.2.3 Main Circuit Breaker Features
General Requirementsfor MCB
The MCB has to be specified according to the rated primary voltage andcurrent of the converter transformer. It should also meet the specific driverequirements (some items require proper coordination with the instrumen-tation and protection equipment). The MCB must be capable:
• to connect and maintain nominal load currents and clear short-circuitcurrents
• to tolerate the transformer inrush current without tripping
• to clear transformer secondary short circuits within 250 ms (the timeincludes the pick-up time of the protection relay and the opening timeof the MCB)
• close in response to a close command
• open within 160 ms in response to an open command (signal activewhen high)
• open within 160 ms in response to a trip command (signal activewhen low)

MCB Instrumentationand Protection
Equipment
Appropriate current transformers and protection relaying must be providedto protect transformer and transformer primary cables. The intendedapproach for protection is shown in Figure 8-4. As shown in the figure theprotection can be considered to consist of three areas. The first areaidentified as Transformer Primary Fault Protection is an instantaneous triparea that protects against short circuits in the transformer primarywindings or in the cables supplying the transformer primary. The lowerlevel of the trip threshold should be adjusted high enough to insure thatnuisance tripping does not occur due to transformer inrush currents. Thesecond area identified as Transformer Secondary Fault Protection is ashort delay trip area that protects against short circuits in the transformersecondary windings, the cables from the transformer secondaries to theACS 1000, or in the input rectifier stages of the ACS 1000. The short timedelay provided should be adjustable and should be set long enough toinsure that the protection does not trip due to transformer inrush current.The trip level should be adjusted low enough to insure that tripping willoccur within 100 ms (including MCB delay time) even if transformers withhigh input impedance are used. The final area identified as OverloadProtection should provide long term overload protection with an inversetime characteristic. This area is intended to protect the transformer andcables from long term overload conditions.

Required current transformersshould be sized in accordance with the rated current levels of thetransformer. Basic protection configuration and connection should be aspreviously shown in Figure 8-2 and Figure 8-3.
Figure 8-4 Sample protection scheme
All ACS 1000 converters must be supplied from an isolation transformerwith multiple phase-shifted secondary windings, designed in accordancewith the pulse number of the input bridge. For 12-pulse systems thesecondary side of the transformer has one star and one delta winding.This creates the 30° phase shift between the two 3-phase secondarywindings, that is necessary to facilitate 12-pulse input bridge operation.The secondary windings of transformers for ACS 1000 converters with 24-pulse rectifier bridge are to be designed to provide a 15° phase shift.
A second purpose of the transformer is to provide sufficient impedance tolimit the line harmonics to acceptable levels.
The transformer may be an oil-immersed or a dry type. Based oninstallation requirements of the application, the transformer may belocated remote from the ACS 1000 drive equipment or nearby, evenintegration into the drive is possible. For requirements regarding themaximum cable length between transformer and ACS 1000 see AppendixB - Technical Data .
The transformer may be supplied from ABB or alternatively from a thirdparty supplier in accordance with the specifications provided by ABB. Thedesign of the transformer must take into account site-specific lineconditions (voltage, short circuit capacity, existing harmonics, etc.) toinsure compliance with harmonic standards invoked by the specifications.Transformer quality is critical with respect to effecting proper limitation ofharmonic currents and voltages.

Chapter 8 - Selecting the Drive System
When determining the power rating of the transformer, power andefficiency of the motor, power factor and efficiency of the ACS 1000converter and harmonic loading of the transformer must all be considered.
For selecting an appropriate ABB ACS 1000 transformer or for specifiyinga generic transformer, please contact your ABB representative.
The rating tables for selecting the ACS 1000 can be found in this chapter.
In general the ACS 1000 converter is selected according to the ratedmotor power. The rated output current of the ACS 1000 should bechecked to insure that it is higher than or equal to the rated motor current.
If a motor with 6 or more poles is used, the nominal motor current usuallyincreases as compared to a motor with fewer poles. This may result in adifferent output filter configuration (see ACS 1000 Output Filter below). Insuch cases, please contact your ABB representative for further assistancebefore making a final drive selection.
When determining the appropriate size of the ACS 1000 converter for aparticular application the following factors need to be considered:
• ambient temperature
• temperature of the cooling media
• installation site altitude
• frostproofing of the cooling water
• the presence of a redundant cooling fan
• type of air filter.
Please refer to Appendix B - Technical Data for details on environmentalaspects.
8.4.1 ACS 1000 Output Filter
The standard ACS 1000 output filter is appropriate for 2 to 6-pole motors.For higher numbers of poles a different filter configuration is sometimesneeded. The modular and flexible filter design allows the ACS 1000 to beconfigured for 2 to 20-pole motors (and even higher numbers of poles). Todetermine the appropriate ACS 1000 configuration please contact yourABB representative.
8.4.2 Non Quadratic Load Applications
For constant torque or constant power applications a high overloadability(start-up torque) is usually required. This overloadability, together withpossibly needed derating for low speed operation, requires someadditional calculations for drive selection. To determine the appropriateACS 1000 please contact your ABB representative.

8.5.2 Selection Criteria
Generally speaking the motor must be selected and sized as required bythe load. Supplying an additional power margin to compensate for PWMinverter operation is not required with the ACS 1000 due to its sinusoidaloutput waveform. After the motor has been selected (or if an existingmotor is being applied) the following parameters are relevant to select theconverter and the transformer:
• load characteristic (the most common characteristic is square torque;for other loads like constant torque or constant power applications,please contact your ABB representative)
• overloadability requirements
• motor voltage
• number of motor poles
• shaft power (nominal)
• shaft speed (nominal)
• rated current (nominal)
• motor efficiency
• motor power factor.
Special attention must be paid to the motor cooling in variable speedapplications. If the motor is self-ventilated, long-time operation at lowspeeds will usually require some derating to compensate for the reducedcooling.
Depending on the mechanical configuration of the motor, load, gear-boxand shaft there may be some critical speeds within the operating speedrange of the drive. The critical speeds have to be known and if they haveto be avoided the appropriate parameter settings have to be made.Special attention has to be paid to variable speed applications using two-pole motors, since there is usually a critical motor speed below its ratedspeed. For more information see Chapter 6 - Standard Functions, CriticalSpeed.
8.5.3 Retrofit
Due to its specific topology the ACS 1000 can supply standard mediumvoltage motors (existing or new) without applying thermal derating factors.In addition, due to its sinusoidal output waveform, standard mediumvoltage winding insulation is sufficient.
To avoid risk of bearing currents and related consequential damages, onemotor bearing should be insulated (the one at the non-driven shaft end).This is actually a typical accessory even for most direct on-line operatedmotors. If, nevertheless, such a bearing is not available (e.g. for olderexisting motors), a grounding brush can be installed on either shaft end.
74 ACS 1000 Technical Catalog
Chapter 8 - Selecting the Drive System
Although from an electrical point of view no restrictions exist for variablespeed operation with retrofit motors, attention should be paid to possiblemotor and load restrictions such as insufficient lubrication or reducedcooling at low speed, critical speed areas within the targeted operatingrange that need to be avoided, etc. Also the maximum (i.e. rated) speedof the motor should under no circumstances be increased withoutauthorization from the manufacturer of each component of the drive trainconcerned.
8.5.4 Torsional Excitation
Due to its sinusoidal output voltage and current waveforms and itssuperior control performance from DTC the ACS 1000 will not introduceany significant torsional excitations to the motor shaft. Therefore atorsional analysis for the sake of applying a frequency converter is notrequired for common applications and normal mechanical shaftarrangements.
ACS 1000 Technical Catalog 75
Appendix A - Installation Guidelines
Ambient conditions may require to derate the drive due to the presence ofelevated air temperature, altitude, or cooling water temperature. Sufficientair flow must be available. Other ambient factors such as relative humidity,air contamination, shock and vibration must also be in compliance withstated maximum permissible levels.
See Appendix B - Technical Data for load capacity derating factors andother requirements related to ambient conditions.
Converter Enclosure The standard IP protection classes for the converter enclosure accordingto IEC 529 are:
• IP21 (for air-cooled converters)
• IP31 (for water-cooled converters).
Higher IP-protection classes for the converter enclosure are optional.Please refer to Chapter 7 - Options.

as stated in this manual appears to be in conflict with the requirements,please contact your local ABB representative for further assistance.
For information regarding Main Circuit Breaker / Controller,Instrumentation and Protection Equipment refer to Chapter 6 - StandardFunctions and Chapter 8 - Selecting the Drive System.
Transformer Primary Cables
The cables from the Main Circuit Breaker (MCB) to the Transformerprimary side has no special requirements. It should carry a voltage ratingconsistent with the voltage present in the primary circuit. The ampacityrating should be consistent with the size of the transformer being suppliedand the protection settings of the protection equipment. Derating of cableampacity in accordance with maximum expected ambient temperature,raceway fill factors and any other factors required by local electrical codesshould be applied. Installation should be in compliance with standardindustrial practice for medium voltage equipment.
If required by local electrical code, an equipment safety ground wireshould be supplied either separately or by including it in the 3- core cable.The ampacity of this conductor should be in accordance with the code.
Transformer Secondary Cables
The cables from the transformer secondary windings to the ACS 1000main power input buses, are exposed to common mode voltages, resultingfrom normal inverter operation. For this reason it is necessary to usecables rated for insulation levels of 5 kV (phase to earth) or higher for alltransformer secondary connections, regardless of the transformersecondary voltage level (1327 V, 1903 V, or 2305 V). Cables rated for 5 kVare typically used in North America, in Europe cables rated for 6kV/10 kVare common.
In order to insure compliance with EMC requirements and to provide a lowimpedance, high frequency path through which the common modecurrents can flow, a shielded cable is recommended. Shields should beterminated and grounded at the shortest possible way at both cabletermination points. The ACS 1000 includes a vertical ground bus withinthe cable termination section in order to facilitate above requirement.
A non-shielded cable with a continuous corrugated aluminum armor maybe used as an alternative to the shielded cable described above. Steelwire armored or interlocked aluminum armored cable should not be used.Cable terminal ends with electrical contact all around its periphery to thearmor should be used to terminate the cable ends to the ground.
The ampacity rating of the cable should be in consistency with 125% of thetransformer nominal output current and the settings of the protectionequipment in order to allow for the harmonic content. Derating of cableampacity in accordance with maximum expected ambient temperature,raceway fill factors and any other factors required by local electrical codes
ACS 1000 Technical Catalog 81
Appendix A - Installation Guidelines
should be applied. Installation should be in compliance with standardindustrial practice for medium voltage equipment.
If required by local electrical code, an equipment safety ground wireshould be supplied separately. The ampacity of this conductor shall be inaccordance with the code.
For information regarding the maximum length of the transformersecondary cables see Appendix B - Technical Data.
Motor Cables
There are no special requirements to be considered for the motor cables.The maximum cable length is limited to 1000 m (3281 ft). A voltage ratingconsistent with the voltage present at the motor must be selected. Theampacity rating should be consistent with the size of the motor beingsupplied and the overload settings of the motor protection software.Derating of cable ampacity in accordance with maximum expectedambient temperature, raceway fill factors, and any other factors requiredby local electrical codes should be applied. Installation should comply withstandard industrial practice for medium voltage equipment.
Cable screening is not required for the motor cables, since the converteroutput voltage and current are sinusoidal. Therefore no measures againstcommon mode currents are needed.
If required by local electrical code an equipment safety ground wire shouldbe supplied separately. The ampacity of this conductor shall be in accor-dance with the code.
Motor cables are terminated within the ACS 1000 cabinet in the same wayas the transformer secondary cables (see Figure A-5).
Power Cable Dimensions
In order to determine the exact dimensions for a specific project, the actualsituation (method of installation, voltage drop due to cable length etc.) andlocal regulations must be considered. Refer also to the specificationssupplied by the power cable manufacturer.
Equipment Grounding
It is recommended that the ACS 1000 ground bus is connected to the plantground bus. The recommended cross-section of the ground connectiondepends on the motor cable cross-section.
Auxiliary Power Cables
A 3-phase cable without neutral connector is required for auxiliary powersupply. Type and ratings are to be selected according to local regulations.For ratings see also Appendix B - Technical Data.
82 ACS 1000 Technical Catalog
Appendix A - Installation Guidelines
Control Cables
Control cables should be in accordance with Table A-2. Cable shieldsshould be terminated on the ACS 1000 end only. Either single or multipletwisted pair cables may be used.
Table A-2 Control cable requirements
Cable Routing
Power Cables Routing of mains and motor cables must be carried out in compliance withthe local regulations and according to the specifications and recommen-dations of the cable manufacturer.
• For best EMC performance, shielded three phase cables arerecommended.
• If single phase cables are used, the cables with the three differentphases must be grouped close together to ensure best EMCperformance.
• Phase interchange must be accomplished according to localregulations.
• For high power ratings, a maximum of two cables per motor phasecan be accommodated by the gland plates of the ACS 1000.
• If the cross-section of the cable shielding is less than 50% of thecross-section of one phase, an additional grounding wire should belaid along the power cables to avoid excessive heat losses in the ca-ble shieldings. Please refer to the local regulations for further details.
Cable Termination Cables must be terminated with connectors according to the cable manu-facturer’s requirements.
Grounding Wire Routing of the grounding connection must comply with local regulations.
Control Cables Control cables should not be laid in parallel to the power cables. If thiscannot be avoided, a minimum distance of 30 cm (12 inches) must bemaintained between control and power cables.
Control and power cables should be crossed at an angle of 90°.

ACS 1000 Cable Entry and Termination
Access to the power termination section of the ACS 1000 is via the controlcabinet, located on the left of the converter. A bolted access door islocated behind the control swing frame. Once the access door is openedall power terminations are readily available. As an aid to interfacing themain power connections, removable bus stubs are included.
Figure A-5 shows a typical example of how transformer and motor cablesare connected to the internal bus system of the ACS 1000.
Cables can be entered through the cabinet roof or from the bottom. If thecable entry is from below, the gland plates mounted on top of the cabletermination section must be relocated to the bottom and the bottom coverplate must be fixed to the top of the cabinet.

Relative Humidity The permitted ranges for relative humidity are:
• 5…95%, no condensation is allowed
• 5…60%, if corrosive gases are present.
Vibration The ACS 1000 can be exposed to the following maximum values for vibra-tion:
• 0.3 mm (2…9 Hz)
• 1 m/s2 (2…200 Hz), sinusoidal (according to IEC 721-3-3).
Sound Pressure Level • < 75 dB (A) for air-cooled types
• < 70 dB (A) for water-cooled types.
Air-cooled Converters
Ambient Temperature The derating factor for air-cooled converters with enclosure class IP21 isas follows:
Above +40 °C (+104 °F) the rated output current is decreased by 1.5 %for each additional 1 °C (0.85 % for each 1° F) up to the maximumpermitted temperature of +50 °C (+122 °F).
Example: If the ambient temperature is 50 °C the derating factor is calcu-lated as 100% - 1.5 %/°C · 10 °C = 85%. Hence, the maximum outputcurrent is 85% of the rated value.
Derating for Air Filters Depending on the mesh size of the filter mat the derating factors as statedin Table B-4 apply to the rated output power:

100 ACS 1000 Technical Catalog
Appendix D - Applicable Codes and Standards
The ACS 1000 frequency converter is marked with a CE symbol. The CEmarking indicates that the ACS 1000 complies with the basic technicalrequirements and conformity valuation criteria and is an essentialrequirement of the relevant EC Directives.
The CE marking is mainly for the benefit of authorities throughout theCommon European Market.
Low Voltage Directive
Low Voltage Directive73/23 EEC modified by 93/68 EEC.
This directive concerns all electrical equipment with nominal voltage levelsof 50..1000 VAC and 75..1500 VDC.
The aim of the directive is to protect against electrical, mechanical, fire andradiation hazards. It tries to insure that safe products are placed on themarket.
Compliance with theLow Voltage Directive
The ACS 1000 fully complies with the Low Voltage Directive as far asenclosure, auxiliary supply and I/O ports are concerned. The Declarationof Conformity will be enclosed in the ACS 1000 delivery.
The Low Voltage Directive is not applicable for the medium-voltage sectionof the ACS 1000. However, the medium-voltage section fulfills the require-ments of the standard EN 50178 (Electronic equipment for use in powerinstallations).
Machinery Directive
89/392 EEC modified by 91/368; 93/44, 93/68 and 98/37EEC.
This directive concerns all combinations of mechanically joined compo-nents, where at least one part is moving.

Appendix D - Applicable Codes and Standards
Compliance with theMachinery Directive
On its own, the ACS 1000 does not have a functional value to the user: Italways needs its motor coupled to the driven load before it can functioneffectively.
Therefore, the Machinery Directive is not applicable for the ACS 1000.
EMC Directive
89/336 EEC modified by 91/263; 92/31; 93/68 and 93/97EEC.
EMC stands for Electromagnetic Compatibility. It is the ability of electrical/electronic equipment to operate without problems within anelectromagnetic environment. Likewise, the equipment must not disturb orinterfere with any other neighboring electrical equipment or system.
Emissions
The source of high-frequency emission of frequency converters is fastswitching of IGCTs and control electronics. The high-frequency emissioncan propagate by conduction and radiation.
Immunity
Electrical equipment should be immune to high-frequency and low-frequency phenomena. High-frequency phenomena include electrostaticdischarge (ESD), fast transient burst, radiating electromagnetic field,conducting radio frequency disturbance and electrical surge. Typical lowfrequency phenomena are mains voltage harmonics, notches andimbalance.
Compliance with theEMC Directive
The EMC Directive applies to the ACS 1000 as far as the enclosure, theauxiliary supply and the I/O ports are concerned. The Declaration ofConformity for industrial environment signed by ABB is enclosed in theACS 1000 delivery. The two applicable standards, EN 50081-2 (Emis-sions) and EN 50082-2 (Immunity) have been met.
As far as the medium-voltage ports are concerned the EMC Directive isnot applicable. The standard IEC 1800-3: Adjustable speed electricalpower drive systems - Part 3: EMC product standard including specific testmethods, states: “For supply voltages higher than 1000 VAC rms, EMCrequirements result from agreement between manufacturer / supplier anduser.”
In order to make sure that the whole system is electromagneticallycompatible within its surrounding the installation regulations have to bestrictly observed. Following the grounding regulations, instructions forcable entries as well as for cable laying is extremely important.
The ACS 1000 is installed with screened control and main power supplycables that are specified in Appendix A - Installation Guidlines.
The installation of the ACS 1000 shall be performed as described in theACS 1000 User’s Manual.
