Proportional gain of the current controller.
The correct value is calculated from the motor data.
Unit: 1
Value range: 1...32767
Default setting:
Adjustment value:
Integral gain of the current controller.
The correct value is calculated from the motor data.
Unit: 1
Value range: 1...32767
Default setting:
Adjustment value:
The peak torque limit prevents the motor from exceeding its
breakdown torque limit. If the torque limit is reached, the acceleration
process will take longer with a full load. This can also cause the car to
over shoot the floor during deceleration. This value can be raised.
The maximum torque during emergency operation is activated
through parameter LF.61. This allows the drive to limit the torque
and therefore the output current to the rated value to prevent the drive
from drawing too much current from a battery back up supply.
Unit: pound feet (lb ft)
Value range:
Default setting:
0.LF.36
This initial low setting protects the motor from high
current in case the encoder position is wrong.)

Note: For PM motors to run with 100% load in the car, it
may be necessary to raise this value to 200%...240% of
LF.17 based on the motor manufacturers rated peak
torque.
Default setting:
1.LF.36

3 x Rated motor torque for IM
approx. 3 x LF.17
1.5 x Rated motor torque for PM motors
approx. 1.5 x LF.17.
1.LF.36 = LF.17
