2.4 Product Overview

A frequency converter is an electronic motor controllerthat converts AC mains input into a variable AC waveformoutput. The frequency and voltage of the output areregulated to control the motor speed or torque. Thefrequency converter can vary the speed of the motor inresponse to system feedback, such as position sensors on aconveyor belt. The frequency converter can also regulatethe motor by responding to remote commands fromexternal controllers.

In addition, the frequency converter monitors the systemand motor status, issues warnings or alarms for faultconditions, starts and stops the motor, optimizes energyefficiency, and offers many more control, monitoring, andefficiency functions. Operation and monitoring functionsare available as status indications to an outside controlsystem or serial communication network.

380-480 V At altitudes above 3 km, contact Danfoss regardingPELV

525-600 V At altitudes above 2 km, contact Danfoss regardingPELV.

Table 3.1 Installation in High Altitudes

3.2 Pre-Installation Checklist

• Before unpacking the frequency converter, ensurethe packaging is intact. If any damage hasoccurred, immediately contact the shippingcompany to claim the damage.

• Before unpacking the frequency converter, locateit as close as possible to the final installation site.

• Compare the model number on the nameplate towhat was ordered to verify the properequipment.

• Ensure each of the following are rated for thesame voltage:

• Mains (power)

• Frequency converter

• Motor

• Ensure that frequency converter output currentrating is equal to or greater than motor full loadcurrent for peak motor performance.

• Motor size and frequency converterpower must match for proper overloadprotection.

• If frequency converter rating is less thanmotor, full motor output cannot beachieved.

3.3 Mechanical Installation

3.3.1 Cooling

• Top and bottom clearance for air cooling must beprovided. Generally, 225 mm (9 in) is required.

• Improper mounting can result in over heatingand reduced performance

• Derating for temperatures starting between 45 °C(113 °F) and 50 °C (122 °F) and elevation 1000 m(3300 ft) above sea level must be considered. SeeVLT® Design Guide for detailed information.

The high power Danfoss VLT frequency converters utilize aback-channel cooling concept that removes heatsinkcooling air, which carries approximately 90% of the heatout of the back channel of the frequency converters. Theback-channel air can be redirected from the panel or roomusing one of the kits below.

NOTEFor ordering numbers, see the VLT High Power DrivesSelection Guide, PB.56.B1.02.

Duct coolingA back-channel cooling kit is available to direct theheatsink cooling air out of the panel when an IP20/chassisfrequency converters is installed in a Rittal enclosure. Useof this kit reduces the heat in the panel and smaller doorfans can be specified on the enclosure.

Cooling out the back (top and bottom covers)The back channel cooling air can be ventilated out of theroom so that the heat from the back channel is notdissipated into the control room.

Installation VLT® Refrigeration Drive 110-250 kW Operating Instructions


33

A door fan(s) is required on the enclosure to remove theheat not contained in the backchannel of the frequencyconverters and any additional losses generated by othercomponents inside the enclosure. The total required airflow must be calculated so that the appropriate fans canbe selected.

AirflowThe necessary airflow over the heat sink must be secured.The flow rate is shown in Table 3.2.

The fan runs for the following reasons:

• AMA

• DC Hold

• Pre-Mag

• DC Brake

• 60% of nominal current is exceeded

• Specific heatsink temperature exceeded (powersize dependent).

• Specific Power Card ambient temperatureexceeded (power size dependent)

WARNINGEQUIPMENT HAZARD!Rotating shafts and electrical equipment can be hazardous.All electrical work must conform to national and localelectrical codes. It is strongly recommended that instal-lation, start up, and maintenance be performed only bytrained and qualified personnel. Failure to follow theseguidelines could result in death or serious injury.

CAUTIONWIRING ISOLATION!Run input power, motor wiring and control wiring in threeseparate metallic conduits or use separated shielded cablefor high frequency noise isolation. Failure to isolate power,motor and control wiring could result in less thanoptimum frequency converter and associated equipmentperformance.



33

For personal safety, comply with the followingrequirements

• Electronic controls equipment is connected tohazardous mains voltage. Extreme care should betaken to protect against electrical hazards whenapplying power to the unit.

• Run motor cables from multiple frequencyconverters separately. Induced voltage fromoutput motor cables run together can chargeequipment capacitors even with the equipmentturned off and locked out.

• Field wiring terminals are not intended to receivea conductor one size larger.

Overload and Equipment Protection

• An electronically activated function within thefrequency converter provides overload protectionfor the motor. The overload calculates the level ofincrease to activate timing for the trip (controlleroutput stop) function. The higher the currentdraw, the quicker the trip response. The overloadprovides Class 20 motor protection. See fordetails on the trip function.

• Because the motor wiring carries high frequencycurrent, it is important that wiring for mains,motor power, and control are run separately. Usemetallic conduit or separated shielded wire. SeeIllustration 3.3. Failure to isolate power, motor,and control wiring could result in less thanoptimum equipment performance.

• All frequency converters must be provided withshort-circuit and over-current protection. Inputfusing is required to provide this protection, seeIllustration 3.4. If not factory supplied, fuses mustbe provided by the installer as part of installation.See maximum fuse ratings in 11.3.1 Protection.

3.4.2 Earth (Ground) Requirements

WARNINGEARTHING (GROUNDING) HAZARD!For operator safety, it is important to earth (ground) thefrequency converter properly in accordance with nationaland local electrical codes as well as instructions containedwithin this document. Do not use conduit connected tothe frequency converter as a replacement for propergrounding. Earth (ground) currents are higher than 3.5 mA.Failure to earth (ground) the frequency converter properlycould result in death or serious injury.Earthing (grounding)hazard

NOTEIt is the responsibility of the user or certified electricalinstaller to ensure correct earthing (grounding) of theequipment in accordance with national and local electricalcodes and standards.

• Follow all local and national electrical codes toearth (ground) electrical equipment properly.

• Proper protective earthing (grounding) forequipment with earth (ground) currents higherthan 3.5 mA must be established, see3.4.2.1 Leakage Current (>3.5 mA).

• A dedicated earth wire (ground wire) is requiredfor input power, motor power and control wiring.

• Use the clamps provided with the equipment forproper earth connections (ground connections).

• Do not earth (ground) one frequency converter toanother in a “daisy chain” fashion.

• Keep the earth (ground) wire connections asshort as possible.

• Using high-strand wire to reduce electrical noiseis recommended.

• Follow motor manufacturer wiring requirements.

3.4.2.1 Leakage Current (>3.5 mA)

Follow national and local codes regarding protectiveearthing of equipment with a leakage current > 3.5 mA.Frequency converter technology implies high frequencyswitching at high power. This will generate a leakagecurrent in the earth connection. A fault current in thefrequency converter at the output power terminals mightcontain a DC component, which can charge the filtercapacitors and cause a transient earth current. The earthleakage current depends on various system configurationsincluding RFI filtering, screened motor cables, andfrequency converter power.

EN/IEC61800-5-1 (Power Drive System Product Standard)requires special care if the leakage current exceeds 3.5 mA.

Earthing (grounding) must be reinforced in one of thefollowing ways:

• Earth (ground) wire of at least 10 mm2

• Two separate earth (ground) wires bothcomplying with the dimensioning rules.

See EN 60364-5-54 § 543.7 for further information.

Using RCDsWhere residual current devices (RCDs)–also known as earthleakage circuit breakers (ELCBs)–are used, comply with thefollowing: residual current devices (RCDs)

• Use RCDs of type B only, which are capable ofdetecting AC and DC currents.

• Use RCDs with an inrush delay to prevent faultsdue to transient earth currents.

• Dimension RCDs according to the system configu-ration and environmental considerations.

• All frequency converters may be used with anisolated input source as well as with earth(ground) reference power lines. When suppliedfrom an isolated mains source (IT mains orfloating delta) or TT/TN-S mains with a groundedleg (grounded delta), set 14-50 RFI Filter to OFF.When off, the internal RFI filter capacitorsbetween the chassis and the intermediate circuitare isolated to avoid damage to the intermediatecircuit and to reduce earth (ground) capacitycurrents in accordance with IEC 61800-3.

3.5 Control Wiring Connection

• Isolate control wiring from high powercomponents in the frequency converter.

• If the frequency converter is connected to athermistor, for PELV isolation, optional thermistorcontrol wiring must be reinforced/doubleinsulated. A 24 V DC supply voltage isrecommended.

3.5.1 Access

All terminals to the control cables are located underneaththe LCP on the inside of the frequency converter. Toaccess, open the door (IP21/54) or remove the front panel(IP20).

3.5.2 Using Screened Control Cables

Danfoss recommends braided screened/armoured cables tooptimise EMC immunity of the control cables and the EMCemission from the motor cables.

3.5.3 Earthing (Grounding) of ScreenedControl Cables

Correct screeningThe preferred method in most cases is to secure controland serial communication cables with screening clampsprovided at both ends to ensure best possible highfrequency cable contact. If the earth (ground) potentialbetween the frequency converter and the PLC is different,electric noise may occur that will disturb the entire system.Solve this problem by fitting an equalizing cable next tothe control cable. Minimum cable cross section: 16 mm2.

3.5.6 Control Terminal Functions

Frequency converter functions are commanded byreceiving control input signals.

• Each terminal must be programmed for thefunction it will be supporting in the parametersassociated with that terminal. See and forterminals and associated parameters.

• It is important to confirm that the controlterminal is programmed for the correct function.See for details on accessing parameters andprogramming.

• The default terminal programming is intended toinitiate frequency converter functioning in atypical operational mode.

3.6 Serial Communication

RS-485 is a two-wire bus interface compatible with multi-drop network topology, i.e. nodes can be connected as abus, or via drop cables from a common trunk line. A totalof 32 nodes can be connected to one network segment.Repeaters divide network segments. Each repeaterfunctions as a node within the segment in which it isinstalled. Each node connected within a given networkmust have a unique node address across all segments.Terminate each segment at both ends, using either thetermination switch (S801) of the frequency converter or abiased termination resistor network. Always use screenedtwisted pair (STP) cable for bus cabling, and always followgood common installation practice.Low-impedance earth (ground) connection of the screen atevery node is important, including at high frequencies.Thus, connect a large surface of the screen to earth(ground), for example with a cable clamp or a conductivecable gland. It may be necessary to apply potential-equalizing cables to maintain the same earth (ground)

4.2 Applying Power to the Frequency Converter

WARNINGHIGH VOLTAGE!Frequency converters contain high voltage whenconnected to AC mains. Installation, start-up andmaintenance should be performed by qualified personnelonly. Failure to perform installation, start-up andmaintenance by qualified personnel could result in deathor serious injury.

WARNINGUNINTENDED START!When the frequency converter is connected to AC mains,the motor may start at any time. The frequency converter,motor, and any driven equipment must be in operationalreadiness. Failure to be in operational readiness when thefrequency converter is connected to AC mains could resultin death, serious injury, equipment, or property damage.

1. Confirm input voltage is balanced within 3%. Ifnot, correct input voltage imbalance beforeproceeding. Repeat procedure after voltagecorrection.

2. Ensure optional equipment wiring, if present,matches installation application.

3. Ensure that all operator devices are in the OFFposition. Panel doors closed or cover mounted.

4. Apply power to the unit. DO NOT start thefrequency converter at this time. For units with adisconnect switch, turn to the ON position toapply power to the frequency converter.

NOTEIf the status line at the bottom of the LCP reads AUTOREMOTE COAST, this indicates that the unit is ready tooperate but is missing an input signal on terminal 27.

4.3 Basic Operational Programming

4.3.1 Set-up Wizard

The built -in “wizard” menu guides the installer throughthe set -up of the frequency converter in a clear andstructured manner, and has been constructed withreference to the industries refrigeration engineers, toensure that the text and language used makes completesense to the installer.At start-up the FC 103 asks the user run the VLT DriveApplication Guide or to skip it (until it has been run, theFC 103 will ask every time at start-up), thereafter in the

event of power failure the application guide is accessedthrough the Quick menu screen.If [Cancel] is pressed, the FC 103 will return to the statusscreen. An automatic timer will cancel the wizard after 5min. of inactivity (no keys pressed). The wizard must be re-entered through the Quick Menu when it has been runonce.Answering the questions on the screens takes the userthough a complete set-up for the FC 103. Most standardrefrigeration applications can be setup by using thisApplication Guide. Advanced features must be accessedthough the menu structure (Quick Menu or Main Menu) inthe frequency converter.

The FC 103 Wizard covers all standard settings for:- Compressors

- Single fan and pump

- Condenser fans

These applications are then further expanded to allowcontrol of the frequency converter to be controlled via thefrequency converter's own internal PID controllers or froman external control signal.

After completing set-up, choose to re-run wizard or startapplication

The Application Guide can be cancelled at any time bypressing [Back]. The Application Guide can be re-enteredthrough the Quick Menu. When re-entering the ApplicationGuide, the user will be asked to keep previous changes tothe factory set-up or to restore default values.

The quick menu is intended for initial start up (Q2-** QuickSet Up) and detailed instructions for common frequencyconverter applications (Q3-** Function Set Up). Step-by-stepinstructions are provided. These instructions enable theuser to walk through the parameters used forprogramming applications in their proper sequence. Dataentered in a parameter can change the options available inthe parameters following that entry. The quick menupresents easy guidelines for getting most systems up andrunning.

The main menu accesses all parameters and allows foradvanced frequency converter applications.

6.2 Programming Example

Here is an example for programming the frequencyconverter for a common application in open loop usingthe quick menu.

• This procedure programs the frequency converterto receive a 0-10 V DC analog control signal oninput terminal 53

• The frequency converter will respond byproviding 6-60 Hz output to the motor propor-tional to the input signal (0-10 V DC = 6-60 Hz)

Select the following parameters using the navigation keysto scroll to the titles and press [OK] after each action.

9 Warnings and Alarms

9.1 System Monitoring

The frequency converter monitors the condition of itsinput power, output, and motor factors as well as othersystem performance indicators. A warning or alarm maynot necessarily indicate a problem internal to thefrequency converter itself. In many cases, it indicates failureconditions from input voltage, motor load or temperature,external signals, or other areas monitored by the frequencyconverter’s internal logic. Be sure to investigate those areasexterior to the frequency converter as indicated in thealarm or warning.

9.2 Warning and Alarm Types

9.2.1 Warnings

A warning is issued when an alarm condition is impendingor when an abnormal operating condition is present andmay result in the frequency converter issuing an alarm. Awarning clears by itself when the abnormal condition isremoved.

9.2.2 Alarm Trip

An alarm is issued when the frequency converter istripped, that is, the frequency converter suspendsoperation to prevent frequency converter or systemdamage. The motor will coast to a stop. The frequencyconverter logic will continue to operate and monitor thefrequency converter status. After the fault condition isremedied, the frequency converter can be reset. It willthen be ready to start operation again.

A trip can be reset in any of 4 ways:

• Press [Reset]

• Digital reset input command

• Serial communication reset input command

• Auto reset

9.2.3 Alarm Trip-lock

An alarm that causes the frequency converter to trip-lockrequires that input power be cycled. The motor will coastto a stop. The frequency converter logic will continue tooperate and monitor the frequency converter status.Remove input power to the frequency converter andcorrect the cause of the fault, then restore power. Thisaction puts the frequency converter into a trip condition asdescribed above and may be reset in any of those 4 ways.

9.5 Fault Messages

The warning/alarm information below defines eachwarning/alarm condition, provides the probable cause forthe condition, and details a remedy or troubleshootingprocedure.

WARNING 1, 10 Volts lowThe control card voltage is below 10 V from terminal 50.Remove some of the load from terminal 50, as the 10 Vsupply is overloaded. Max. 15 mA or minimum 590 Ω.

This condition can be caused by a short in a connectedpotentiometer or improper wiring of the potentiometer.

TroubleshootingRemove the wiring from terminal 50. If the warning clears,the problem is with the customer wiring. If the warningdoes not clear, replace the control card.

WARNING/ALARM 2, Live zero errorThis warning or alarm only appears if programmed by theuser in 6-01 Live Zero Timeout Function. The signal on oneof the analog inputs is less than 50% of the minimumvalue programmed for that input. Broken wiring or faultydevice sending the signal can cause this condition.

Troubleshooting

• Check connections on all the analog inputterminals. Control card terminals 53 and 54 forsignals, terminal 55 common. MCB 101 terminals11 and 12 for signals, terminal 10 common. MCB109 terminals 1, 3, 5 for signals, terminals 2, 4, 6common).

• Check that the frequency converter programmingand switch settings match the analog signal type.

• Perform Input Terminal Signal Test.

WARNING/ALARM 3, No motorNo motor has been connected to the output of thefrequency converter.

WARNING/ALARM 4, Mains phase lossA phase is missing on the supply side, or the mainsvoltage imbalance is too high. This message also appearsfor a fault in the input rectifier on the frequency converter.Options are programmed at 14-12 Function at MainsImbalance.

TroubleshootingCheck the supply voltage and supply currents to thefrequency converter.

WARNING 5, DC link voltage highThe intermediate circuit voltage (DC) is higher than thehigh voltage warning limit. The limit is dependent on thefrequency converter voltage rating. The unit is still active.

WARNING 6, DC link voltage lowThe intermediate circuit voltage (DC) is lower than the lowvoltage warning limit. The limit is dependent on thefrequency converter voltage rating. The unit is still active.

WARNING/ALARM 7, DC overvoltageIf the intermediate circuit voltage exceeds the limit, thefrequency converter trips after a time.

Troubleshooting

• Connect a brake resistor

• Extend the ramp time

• Change the ramp type

• Activate the functions in 2-10 Brake Function

• Increase 14-26 Trip Delay at Inverter Fault

WARNING/ALARM 8, DC under voltageIf the intermediate circuit voltage (DC link) drops belowthe under voltage limit, the frequency converter checks if a24 V DC backup supply is connected. If no 24 V DC backupsupply is connected, the frequency converter trips after afixed time delay. The time delay varies with unit size.

Troubleshooting

• Check that the supply voltage matches thefrequency converter voltage.

• Perform input voltage test.

• Perform soft charge circuit test.

WARNING/ALARM 9, Inverter overloadThe frequency converter is about to cut out because of anoverload (too high current for too long). The counter forelectronic, thermal inverter protection gives a warning at98% and trips at 100%, while giving an alarm. Thefrequency converter cannot be reset until the counter isbelow 90%.The fault is that the frequency converter is overloaded bymore than 100% for too long.

Troubleshooting

• Compare the output current shown on the LCPwith the frequency converter rated current.

• Compare the output current shown on the LCPwith measured motor current.

• Display the Thermal Drive Load on the LCP andmonitor the value. When running above thefrequency converter continuous current rating,the counter should increase. When running belowthe frequency converter continuous currentrating, the counter should decrease.

WARNING/ALARM 10, Motor overload temperatureAccording to the electronic thermal protection (ETR), themotor is too hot. Select whether the frequency convertergives a warning or an alarm when the counter reaches100% in 1-90 Motor Thermal Protection. The fault occurswhen the motor is overloaded by more than 100% for toolong.

Troubleshooting

• Check for motor overheating.

• Check if the motor is mechanically overloaded



99

• Check that the motor current set in 1-24 MotorCurrent is correct.

• Ensure that Motor data in parameters 1-20through 1-25 are set correctly.

• If an external fan is in use, check in 1-91 MotorExternal Fan that it is selected.

• Running AMA in 1-29 Automatic Motor Adaptation(AMA) tunes the frequency converter to themotor more accurately and reduces thermalloading.

WARNING/ALARM 11, Motor thermistor over tempThe thermistor might be disconnected. Select whether thefrequency converter gives a warning or an alarm in1-90 Motor Thermal Protection.

Troubleshooting

• Check for motor overheating.

• Check if the motor is mechanically overloaded.

• Check that the thermistor is connected correctlybetween either terminal 53 or 54 (analog voltageinput) and terminal 50 (+10 V supply) and thatthe terminal switch for 53 or 54 is set for voltage.Check 1-93 Thermistor Source selects terminal 53or 54.

• When using digital inputs 18 or 19, check thatthe thermistor is connected correctly betweeneither terminal 18 or 19 (digital input PNP only)and terminal 50.

• If a KTY sensor is used, check for correctconnection between terminals 54 and 55

• If using a thermal switch or thermistor, check thatthe programming if 1-93 Thermistor Resourcematches sensor wiring.

• If using a KTY sensor, check the programming of1-95 KTY Sensor Type, 1-96 KTY ThermistorResource, and 1-97 KTY Threshold level matchsensor wiring.

WARNING/ALARM 12, Torque limitThe torque has exceeded the value in 4-16 Torque LimitMotor Mode or the value in 4-17 Torque Limit GeneratorMode. 14-25 Trip Delay at Torque Limit can change this froma warning only condition to a warning followed by analarm.

Troubleshooting

• If the motor torque limit is exceeded during rampup, extend the ramp up time.

• If the generator torque limit is exceeded duringramp down, extend the ramp down time.

• If torque limit occurs while running, possiblyincrease the torque limit. Be sure the system canoperate safely at a higher torque.

• Check the application for excessive current drawon the motor.

WARNING/ALARM 13, Over currentThe inverter peak current limit (approximately 200% of therated current) is exceeded. The warning lasts about 1.5secs., then the frequency converter trips and issues analarm. This fault may be caused by shock loading or fastacceleration with high inertia loads. If extended mechanicalbrake control is selected, trip can be reset externally.

Troubleshooting

• Remove power and check if the motor shaft canbe turned.

• Check that the motor size matches the frequencyconverter.

• Check parameters 1-20 through 1-25 for correctmotor data.

ALARM 14, Earth (ground) faultThere is current from the output phases to earth, either inthe cable between the frequency converter and the motoror in the motor itself.

Troubleshooting:

• Remove power to the frequency converter andrepair the earth fault.

• Check for earth faults in the motor by measuringthe resistance to ground of the motor leads andthe motor with a megohmmeter.

• Perform current sensor test.

ALARM 15, Hardware mismatchA fitted option is not operational with the present controlboard hardware or software.

Record the value of the following parameters and contactyour Danfoss supplier:

Remove power to the frequency converter and repair theshort circuit.

WARNING/ALARM 17, Control word timeoutThere is no communication to the frequency converter.



9 9

The warning will only be active when 8-04 Control TimeoutFunction is NOT set to OFF.If 8-04 Control Timeout Function is set to Stop and Trip, awarning appears and the frequency converter ramps downuntil it trips then displays an alarm.

Troubleshooting:

• Check connections on the serial communicationcable.

• Increase 8-03 Control Timeout Time

• Check the operation of the communicationequipment.

• Verify a proper installation based on EMCrequirements.

ALARM 18, Start failedThe speed has not been able to exceed AP-70 CompressorStart Max Speed [RPM] during start within the allowed time.(set in AP-72 Compressor Start Max Time to Trip). This maybe caused by a blocked motor.

WARNING 23, Internal fan faultThe fan warning function is an extra protective functionthat checks if the fan is running/mounted. The fan warningcan be disabled in 14-53 Fan Monitor ([0] Disabled).

For the D, E, and F Frame filters, the regulated voltage tothe fans is monitored.

Troubleshooting

• Check fan resistance.

• Check soft charge fuses.

WARNING 24, External fan faultThe fan warning function is an extra protective functionthat checks if the fan is running/mounted. The fan warningcan be disabled in 14-53 Fan Monitor ([0] Disabled).

Troubleshooting



WARNING 25, Brake resistor short circuitThe brake resistor is monitored during operation. If a shortcircuit occurs, the brake function is disabled and thewarning appears. The frequency converter is stilloperational but without the brake function. Remove powerto the frequency converter and replace the brake resistor(see 2-15 Brake Check).

WARNING/ALARM 26, Brake resistor power limitThe power transmitted to the brake resistor is calculated asa mean value over the last 120 s of run time. Thecalculation is based on the intermediate circuit voltage andthe brake resistance value set in 2-16 AC brake Max.Current. The warning is active when the dissipated brakingis higher than 90% of the brake resistance power. If [2] Tripis selected in 2-13 Brake Power Monitoring, the frequencyconverter will trip when the dissipated braking powerreaches 100%.

WARNINGThere is a risk of substantial power being transmitted tothe brake resistor if the brake transistor is short-circuited.

WARNING/ALARM 27, Brake chopper faultThe brake transistor is monitored during operation and if ashort circuit occurs, the brake function is disabled and awarning is issued. The frequency converter is stilloperational but, since the brake transistor has short-circuited, substantial power is transmitted to the brakeresistor, even if it is inactive.Remove power to the frequency converter and remove thebrake resistor.

This alarm/warning could also occur should the brakeresistor overheat. Terminals 104 and 106 are available asbrake resistors Klixon inputs.

WARNING/ALARM 28, Brake check failedThe brake resistor is not connected or not working.Check 2-15 Brake Check.

ALARM 29, Heatsink tempThe maximum temperature of the heatsink has beenexceeded. The temperature fault will not reset until thetemperature falls below a defined heatsink temperature.The trip and reset points are different based on thefrequency converter power size.

TroubleshootingCheck for the following conditions.

• Ambient temperature too high.

• Motor cable too long.

• Incorrect airflow clearance above and below thefrequency converter

• Blocked airflow around the frequency converter.

• Damaged heatsink fan.

• Dirty heatsink.

For the D, E, and F Frame sizes, this alarm is based on thetemperature measured by the heatsink sensor mountedinside the IGBT modules. For the F Frame sizes, this alarmcan also be caused by the thermal sensor in the Rectifiermodule.

CAUTIONConnection to PC is carried out via a standard host/device USB cable.The USB connection is galvanically isolated from the supply voltage (PELV) and other high-voltage terminals.The USB connection is not galvanically isolated from protection earth. Use only isolated laptop/PC as connection to the USBconnector on the frequency converter or an isolated USB cable/converter.

Protection and Features

• Electronic thermal motor protection against overload.

• Temperature monitoring of the heatsink ensures that the frequency converter trips if the temperature reaches apredefined level. An overload temperature cannot be reset until the temperature of the heatsink is below thevalues stated in the tables on the following pages (Guideline - these temperatures may vary for different powersizes, frame sizes, enclosure ratings etc.).

• The frequency converter is protected against short-circuits on motor terminals U, V, W.

• If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).

• Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuitvoltage is too low or too high.

• The frequency converter is protected against earth faults on motor terminals U, V, W.

1) For type of fuse see 11.3 Fuse Specifications

2) American Wire Gauge.

3) Measured using 5 m screened motor cables at rated load and rated frequency.

4) The typical power loss is at nominal load conditions and expected to be within ±15% (tolerence relates tovariety in voltage and cable conditions). Values are based on a typical motor efficiency (eff2/eff3 border line).Motors with lower efficiency will also add to the power loss in the frequency converter and opposite. If theswitching frequency is increased comed to the default setting, the power losses may rise significantly. LCP and



11 11

typical control card power consumptions are included. Further options and customer load may add up to 30 W tothe losses. (Though typical only 4 W extra for a fully loaded control card, or options for slot A or slot B, each).Although measurements are made with state of the art equipment, some measurement inaccuracy must beallowed for (±5%).

11.3 Fuse Specifications

11.3.1 Protection

Branch Circuit Protection:In order to protect the installation against electrical andfire hazard, all branch circuits in an installation, switchgear, machines etc., must be short-circuited and over-current protected according to national/internationalregulations.

Short-circuit Protection:The frequency converter must be protected against short-circuit to avoid electrical or fire hazard. Danfossrecommends using the fuses mentioned below to protectservice personnel and equipment in case of an internalfailure in the frequency conveter. The frequency converterprovides full short-circuit protection in case of a short-circuit on the motor output.

Over-current Protection:Provide overload protection to avoid fire hazard due tooverheating of the cables in the installation. The frequencyconverter is equipped with an internal over-currentprotection that can be used for upstream overloadprotection (UL-applications excluded). See 4-18 CurrentLimit. Moreover, fuses or circuit breakers can be used toprovide the over-current protection in the installation.Over-current protection must always be carried outaccording to national regulations.

11.3.2 Non UL Compliance

If UL/cUL is not to be complied with, we recommend usingthe following fuses, which will ensure compliance withEN50178. In case of malfunction, not following therecommendation may result in unnecessary damage to thefrequency converter.
