Sets the limit value for the motor torque producing current.
Units:
Default:
Min/Max: P.U.
0.0000
-/+8.0000 pu RO Real
359 Motor Flux Est
The Q-axis motor voltage is divided by the motor frequency while field weakening is active.
This value is used to convert the torque command to a motor current (Iqs) command.
Units:
Default:
Min/Max: P.U.
0.0000
-/+8.0000 pu RO Real
360 Min Flux
Sets the smallest level of flux used to convert Par 303 [Motor Torque Ref] to a current
reference above base speed. Note: Changed the minimum value from “0.2500” to “0.1000” for
firmware version 4.001.
Units:
Default:
Min/Max: P.U.
0.2500
0.1000/1.0000

RW Real
361 Flx LpassFilt BW
Sets the bandwidth of the low pass filter that adjusts the response of the flux estimate used in
the torque to current conversion. Since the field time constant varies between motors, a better
control response may be obtained by adjusting the filter time constant. Normally this
parameter is not changed unless a significant disturbance occurs as the motor enters field
weakening AND
Par 360 [Min Flux] is less than 1 per unit.
Units:
Default:
Min/Max: R/S

362 Current Limit Gain
Sets the responsiveness of the current limit. This parameter should not be changed by the
user.
Note: This parameter was added for firmware version 2.03.
Default:
Min/Max: 250
0/10000 RW 16-bit
Integer
363 Ki Current Limit
Current Limit Integral gain. This gain is applied to the current limit error signal to eliminate
steady state current limit error. A larger value increases overshoot during a step of motor
current/load. This parameter should not be changed by the user.
Note: This parameter was added for firmware version 2.03.
Default:
Min/Max: 1500
0/10000 RW 16-bit
Integer
364 Kd Current Limit
Current Limit Derivative gain. This gain is applied to the sensed motor current to anticipate a
current limit condition. A larger value reduces overshoot of the current relative to the current
limit value. This parameter should not be changed by the user.
Note: This parameter was added for firmware version 2.03.

Enter a value to configure the drive's response to an Encoder 0/1 Loss exception event.
•
0 - Ignore configures the drive to continue running, as normal, when this event occurs.
•
1 - Alarm configures the drive to continue running and set the appropriate alarm bit when
this event occurs.
•
2 - FltCoastStop configures the drive to perform a coast stop and set the appropriate fault
bit, in response to this event.
