NR-SOFTSTARTER (M102-M Only) Softstarter applications are for controlling motor accessory softstarter device. M102-M gives start and stop commands to the softstarter unit. The softstarter is set for adjusting motor voltage with it’s own parameters. More information about softstarter can be found from softstarter’s manual.

This starter type supports all protection functions during normal “Running” situation. For motor start and stop period some of the protection functions are disabled by these parameters.

Feeder ‘Feeder’ mode is regarded in M10x as a specific starter type to provide measurement and control functionality. The protection of feeder is not covered in M10x and is normally done by main circuit breaker. The ‘feeder’ mode in M10x is designed to provide a complete intelligent solution in MCC plant where the feeder circuits are usually small but important parts from the whole MCC plant management point of view.

Protection:-

No protection function is designed for feeders application!

Measuring:-

Current, Voltage are measured by M10x. Power, energy and other parameters related to Power factor are NOT correct and should not be refer to!

Protection Function The module provides full protection for motor by supervising three phases voltage, three phases current, earth fault current, PTC sensor, the state of contactors and the state of main switch.


1TNC911112D0204 32

Responding of protection functions is based on the parameters given by user. The operation of separate functions is independent thus protection functions can be active at the same time but the one which indicates the situation first initiate a trip/alarm.

Varies on different applications, protection functions can be activated or deactivated by the upper level system or through parametering tool. Protection characteristics can be adjusted in the same way.

Thermal overload protection Thermal overload protection (TOL) protects the motor against overheating. The motor thermal condition is simulated by a calculation. The result of the calculation is stored in a thermal register and can be reported via operator panel or fieldbus interface.

Calculation is accomplished in a different motor operation conditions, principle presented below, thermal increase and decrease are simulated by TOL protection function for running and stopped motor.

Fig. 21 Principle Fig. of motor thermal simulation

M10x-M simulates thermal conditions in the motor for all operating modes ( Running or Stopped) . This permits maximum utilization of an installation and assures safe protection of the

motor. Thermal overload protection simulation accounts for the temperature rise of both the stator winding and the iron mass of the motor, it gives thorough consideration on the effect of motor overheating due to three phase unbalance during the simulation calculation of motor thermal overload.

There are two thermal models supported by M102-M: Standard or EEx e, but M101-M only supports Standard thermal model. The standard model makes use of parameters Trip class, t6 in thermal overload calculation. The protection of explosion proof three-phase motors with type of protection ‘increased safety’ EEx e is done with two special parameters, the Ia/In ratio ( stall/nominal current ratio ) and Te time.

The following diagram offers the characteristic curve of overload protection, in which the character is adjusted by changing t6( trip time for current ILmax=6 In from the cold state).

Fig. 22 Trip curve from cold condition

The Maximum thermal capacity level is 100%. Maximum level is reached when motor as been running with a current 6xIn at the time t6 starting from the cold state in ambient temp. 40 C

In some applications it is beneficial to be able to bypass the TOL protection momentarily because of the process reasons. The lifetime of the motor will be shortened but it will be more costly to stop the process. TOL-bypass is a special command given through the fieldbus.


1TNC911112D0204 34

There is a dedicated parameter to enable the execution of this command. TOL-bypass function is available only inTOL standard model, thus it cannot be enabled if TOL EEx e model is in use.

When thermal level is above parameterised alarm level there is a possibility to send a bypass command to M10x-M. When bypass function is activated, the thermal image is allowed to rise to 200% level before a trip will occur.

If motor is in overload condition, i.e. ILmax > 1,14 x TFLC (Thermal full load current multiplier reduced by motor ambient temperature), the Overload alarm is active to indicate overload, but time to trip is not updated if the thermal capacity level ( ) is not going to rise above 200% (ITOL < 2). If motor is stopped before trip and the thermal capacity decreases below TOL alarm level the bypass functionality is disabled.

Bypass command is ignored when running under alarm level.

PTC protection (M102-M Only)


1TNC911112D0204

43

PTC protection protects the motor against too high temperature by using PTC-sensor embedded in the stator winding or the bearings. The measuring principle is the current measurement according the transmitters are supposed to be of the 3-wire type. Thus the circuit is independent of the cable-length limitations and the voltage drop in the cable. For M102, you can use a type A temperature sensor with a characteristic curve according to IEC 60947-8.

After PTC trip is executed the resistance of PTC input is compared against the PTC reset level. When resistance of PTC input decreases below the reset level, the PTC protection function executes the function parametrised by “PTC Reset Mode”.

PTC short circuit protection is not supported in M10x.

Undervoltage protection (M102-M Only) M102-M protects the motor against undervoltage condition as “voltage dip”. The undervoltage protection function uses ULmin as the criterion. There are other parameters to be determined, such as alarm level, trip level and trip delay, reset voltage level. The protection characteristic is as follows:

The lowest measured main voltage (Ulmin) is compared against the undervoltage alarm level. When Ulmin decreases below the undervoltage alarm level, an “Undervoltage alarm” alarm is issued.

Start limitation Start limitation helps to protect the motor and also the process against excess number of starts in a given interval. When the number of starts is reached and the motor is switched off, a new start is prevented. The time interval starts from the first start. After the elapse of the time interval the counter is reset to the pre-set value. The permissible motor starts per hour can be obtained from the manufacturers motor and apparatus data sheet. However, the minimum waiting time between two starts shall be complied.


1TNC911112D0204 46

The parameterization of the protection function can be the number of starts per time interval or the time between two consecutive starts. In the first case the user must wait after the trip for the reset to take place before making a start.

Independent of this function, the motor is protected by TOL function and a start is possible only if the thermal capacity is below the startup inhibit level. If motor data specifies the number of starts during a certain time span the advantage of this protection function can be taken of supervising the number of starts. On some other cases process may put requirements for the motor start number thus this protection can be employed.

Functionality is presented in the following example. The next Fig., presents the start limitation protection with 3 starts allowed.

1) Normal situation, after stop command motor can be started normally, “Start 2”. Every start activates an internal timer for the time defined by time interval parameter. The number of active timers are reviewed after every stop command and compared to value of number of starts parameter. Stop command can thus exist during active or elapsed timer.

2) Two timers are still active, thus stop command generates alarm message "Start limitation alarm" and one more start is allowed, “Start 3”.

3) The 3rd start has been executed. A contactor trip and trip message "Start Limitation Trip" alarm will follow when motor is stopped while there are two active timers, here starting from “Start 1”.

4) Trip can be automatically reset when the first timer from “Start 1” is finished. Motor start is possible when all pending trips are reset. Supervision continues with a new timer from “Start 4”

Table 36 Autorestart function parameters

Auto restart function (standard) In standard mode, the reaction of the auto restart function depends on the length of the voltage dip.The following cases show the different reactions of M102-M in different voltage dip situations.

Case 1: Voltage dip< autoreclose time


1TNC911112D0204

49

Fig. 32 Autorestart (Voltage dip< autoreclose time)

If voltage is restored within autoreclose time, motor restarts immediately.

Case 2: autoreclose time<voltage dip< Max. power down time

Fig. 33 Autorestart (autoreclose time<voltage dip< Max. power down time)

If power is restored after autoreclose time but before max power down time, motor will be restarted after the staggered start delay time.


1TNC911112D0204 50

Case 3: Voltage dip> Max. power down time

Fig. 34 Restart (Voltage dip> Max. power down time)

If supply voltage remains below restore level long enough and exceeds max power down time, no automatic restart will be initiated.

Auto restart function (enhanced) If the voltage dip is taken more serious, the enhanced autorestart function can be applied.

In the enhanced mode, the reaction of the auto restart function not only depends on the length of the voltage dip, but also the number of voltage dips within short period of time.

The following cases show the different reactions of M102-M in different voltage dip situations.

Case1: Voltage dip< autoreclose time

Identical to Case1 of standard mode

Case2: autoreclose time<voltage dip< Max. power down time


Case3: Voltage dip> Max. power down time


Case4: 2xdip<200ms within 1s

Fig. 35 Restart (2xdip<200ms within 1s)

If the interval between two voltage dips (which length less than 200ms ) is less than 1 second. Automatic delay restart is triggered after second voltage restore.

Number of Starts M10x-M counts number of start. For each operation cycle M10x-M updates the number of operating cycle in memory map. When start number alarm level is exceeded, M10x-M issues an alarm.

Motor Running Time M10x-M counts motors running hours. When operating running hours limit will be crossed M10x-M issues an “running time” alarm.

Failsafe Functionality M10x-M failsafe function supervises the network interface and connection to the remote devices controlling the motor/starter equipment by M10x-M. Remote device have to refresh the certain M10x-M network input variable to indicate that the control is operating normally and the network interface is in good condition.

When M10x detects loss of communications, failsafe mode will be switched on automatically and corresponding operations will be followed as per parameters settings, i.e.

No operation

Start motor direction 1

Start motor direction 2

Stop motor

Besides, control access to motor will be switched to/remain in local control (hardwire control) and MD control while ignoring previous control access settings. When the communication restore, the control access will recover to the original setting.


1TNC911112D0204 52

Time Synchronization The last alarm, trip and operation message generated by the M10x-M are with time-tag, which is based on the synchronized absolute system time.

M10x-M supports message-based time synchronization. Whenever receiving time synchronization message, M10x-M synchronizes its internal clock with new absolute time received in the message.

M10x-P Control Authority Control Authority M10x Control Authority is the term describing the privileges on allowing motor control operation through M10x. It is also a setting parameter in M10x to define which control access group has privilege to operate the motor via M10x.

Control Access There are three control access groups defined in M10x,

Local Hardwiring:- M10x accepts its commands from the hardwired inputs

Remote Fieldbus:-M10x accepts its commands from PLC or higher control system viia fieldbus. i.e. Modbus or PROFIBUS.

MDx Control:- M10x accepts its commands from operator panel MDx which locates on the front panel of each starter unit on switchgear.

Assign Control Authority There are several means in M10x to assign control authority and decide which control access group has the privilege to control.

Parameter Setting: Select the access group from parameter setting window (Fig 36a). This is the most direct means where control access is defined by parameterization software.


1TNC911112D0204

53

Fig. 36a Parameter Setting of Control Authority

Multi control access group is supported!

Local/Remote Selector Switch: M10x supports hardwired local remote selector switch function which allows selecting control access groups via hardwired inputs. Local/Remote option has to be enabled as shown in Fig36b in this application. Local/Remote Selector Switch wiring is via predefined digital inputs. Please refer to Fig 5 & 6 for detail wiring.

Fig. 36b Enable “Local/Remote” function


1TNC911112D0204 54

Local/Remote Selector Switch will then define if control access goes to “Local “(Local Hardwired ) or “Remote” (Remote Fieldbus). This function does not include the selection of operator panel MDx control which is independent of either “Local” or “Remote” and has to be further defined in this case.

Control Authority

Local Hardwiring Remote Fieldbus MDx Enabled in

False (open input) Disabled Enabled Disabled Enabled

True (close input) Enabled Disabled Enabled Disabled

Fig. 36c “Local/Remote” Selector Switch

There are also two ways of defining MDx control access when Local/Remote selector switch function is enabled, i.e. through “parameter setting” in parameterization software or through hardwired input.

Parameter Setting (Fig 36b)

Hardwired Input,

Use external selector switch to select MDx control. One of the programmable inputs has to be defined as ‘MD Control” to enable the function.

Fig. 36d “MD Control” Selector Switch

When “Loc/R” is enabled (via predefined input, refer to Fig5&6), the control access group options under ‘Control Authority” tab (Fig36b) are limited to

“MD” only. Same as in selecting MDx control. When “ MDx control” is enabled in one of the DIs, the MD control access option under “Control Authority” tab will be gray out.


1TNC911112D0204

In another word, Hardwired Selection has privilege over Parameter Setting Selection in terms of assigning control authority. Main Switch Status (M102-M Only Only) Main switch input (MCB) indicates the status of main switch.

There is no direct main switch input in M101-M. It can be configured through one of the programmable inputs if required.

Programmable Inputs There are three separate programmable inputs in M10x-M. These three inputs can be assigned any of the functions listed below.

Programmable inputs can be used to:

Start1 To use start1 function, local control authority must be enabled.

The start1 input is used to start motor via hardwire. Motor can be running CW/N1 via Start1. This input works in edge triggering mode.

Start 2 To use start2 function, local control authority must be enabled.

The start2 input is used to start motor via hardwire. Motor can be running CCW/N2 via Start2. This input works in edge triggering mode.

Stop To use stop function, local control authority must be enabled.

The stop input is used to stop motor via hardwire. This input works in edge triggering mode.

Process interlock1 The process interlock1 input is used to provide time dependent trip/alarm/stop features based on a switch input. This function is used together with Operation Delay and Operation parameters.

The parameter of Operation Delay sets the amount of time that the Process interlock1 switch can remain inactive on the occurrence of a motor start. If the switch remains inactive for longer than this time, a trip/stop will occur. If there is valid active process interlock1 input detected in the defined operation delay, motor will keep running. And after the operation delay time, the inactive status of process interlock1 input will not affect the running of motor. If the parameter of Operation Delay is set to 0, that the process interlock1 switch must be active while motor is started, which means motor start will not be allowed if the input is inactive.

The parameter of Operation determines whether process interlock1 feature is a trip (reset required in order to restart the motor), a stop (no reset required) or an alarm.

This input works in level check mode.

Case 1: when t1>t2, motor can run normally;

Case 2: when t1<t2, a trip or stop will be performed according to the predefined operation.

Process interlock2 Process interlock2 function is used to provide time dependent trip/alarm/stop features based on a switch input. This function is used together with OPERATION DELAY and OPERATION parameters.

The parameter of OPERATION DELAY sets the amount of time that the process interlock2 switch can be remain active when motor is in running. If the switch remains active for longer than this time, a trip/stop will occur. . If the parameter of OPERATION DELAY is set to 0, that the process interlock2 switch must be inactive while motor is started, which means motor start will not be allowed if the input is active.

OPERATION: this parameter determines whether process interlock feature is a trip (reset required in order to restart the motor), a stop (no reset required) or an alarm.

Case 1: when t1>t2, motor can run normally;

Case 2: when t1<t2, a trip or stop will be performed according to the predefined operation.

Test Switch This input is used to indicate whether the main switch is in the test-position. While in test position, M10x monitors the I/O status and phase current will be zero. Contactor operations by M10x are allowed but all protection functions based on the current and voltage measurement are disabled and the test of control circuit is allowed.

If the current is detected nonzero, all protection functions defined enabled in parameter setting would be enabled automatically. It’s for protecting motor in the case of test switch input is out of work.


ESD Input (Emergency stop) The emergency stop input is used for the emergency stop device. When the input is active, the motor will be stopped and can’t be restarted until the input is inactive. This input works in level check mode that is different from “Stop” function.

PLC Contact1 To use PLC contact1 function, local hardwiring control authority must be enabled.

M10x accepts the commands from PLC to control motor when programmable DI is configured as ‘PLC Contact1’. This input works in edge triggering mode. When the digital input is detected rising edge triggering, the motor runs CW/N1. When the digital input is detected falling edge triggering, the motor stops.

PLC Contact2 To use PLC contact2 function, local hardwiring control authority must be enabled.


1TNC911112D0204 58

M10x accepts the commands from PLC to control motor when programmable DI is configured as ‘PLC Contact2’. This input works in edge triggering mode. When the digital input is detected rising edge triggering, the motor runs CCW/N2. When the digital input is detected falling edge triggering, the motor stops.

Trip Reset The trip reset input is used to reset trip after trip occur.

This input works in edge triggering mode.

Torque Switch Input The input is used to check the status of torque switch used for Actuator Starter. When the input is different from normal state, M10x-M will release all contactor control relays to stop the motor. This input works in level check mode.

NOP No special operation for the NOP function, only for the check of digital input status. This input can be used as status transfer of digital input. This input works in level check mode.

MD Control It will decide whether the control command from MD is active or not. When one of DIs is assigned for ‘MD Control’, the control authority of MD will not be changed via parameterization but relying on the input status of the DI. If the input status is active, motor can be controlled via MD. Whereas the control command from MD is inactive.


Programmable Outputs M101-M has one and M102-M has tow programmable relays output. These outputs can be assigned any of the functions listed below.

Energize on Motor Start Delay : Provides a delayed energization of relay when motor is started.

De-energize on Motor Stop Delay: Provides a delayed de-energization of relay when motor is stopped.

Fieldbus Control: The relay can be energized or de-energized via the serial port.

Interlock0: The relay will energize while the programmable input 0 switch is closed




1TNC911112D0204

Trips: The relay is energized when there is no trip. When a trip occurs, the relay will be de-energized.

Resetting M10x-M will energize the relay.

Ground Fault Trip: The relay is energized when no ground fault trip occurs. When ground fault trip occurs, the relay will

be de-energized. Resetting M10x-M will energize the relay.

TOL: The relay is energized when no thermal overload trip occurs. When thermal overload trip occurs, the relay will be de-energized. Resetting M10x-M will energize the relay.

Watchdog Output: M10x-M has an internal hardware watchdog supervising the behavior of the microprocessor software. Programmable output can be used as signaling output relay for indicating the status of the unit’s internal watchdog. In case of fault the watchdog activates and the relay is energized.

Communication Failure: The relay is energized when no communication failure occurs. When the failure occurs, the relay will be de-energized.

RCU Mode (M101-M Only): This definition is assigned to the programmable out when ‘NR DOL/RCU ‘ or ‘REV DOL/RCU' is selected as motor starter mode. The relay output serves the same function of ‘ de-energized the contactor coil’ as ‘CCC’ output in M102.

Local Remote Output: The relay is energized when the control authority is Remote only .The relay will be de-energized when the control authority is Local and Remote or Local only.

Communication Interface

Overview The physical fieldbus interface inM10x-M is RS485. There are two identical RS485 interfaces built in M10x-M to support full redundancy network design.

The M10x-M implements a subset of the Modicon Modbus RTU serial communication standard. Modbus is a single master/multiple slave type of protocol suitable for a multi drop configuration as provided by RS485 hardware. The M10x-M is always a Modbus slave. They could not be programmed as Modbus masters. Commonly computers or PLCs are acted as masters.

Both monitoring and control are possible using read and write register commands. Other commands are supported to provide additional functions.

RS485 Interface Cable All devices are connected in bus structure. In one segment up to 32 modules can be connected. At the beginning and the end of one segment, the cable is terminated with resistor. The maximum length depends on cable type and baud-rate.

Function Description The following functions are supported by the M10x-M:

FUNCTION CODE 02H - Read Settings and Actual Values



FUNCTION CODE 05H - Execute Operation

FUNCTION CODE 06H - Store Single Setting

FUNCTION CODE 08H – Loop Back Test

FUNCTION CODE 10H - Store Multiple Settings
