Torque Comp
C4-01 Torque Compensation Gain
Torq Comp Gain
This parameter helps to produce better starting torque. It deter-
mines the amount of torque or voltage boost based upon motor cur-
rent and motor resistance.
0.00 to 2.50 1.00 Programming
C4-02
Torque Compensation
Primary Delay Time
Torq Comp Time This parameter adjusts a filter on the output of the torque
compensation function. Increase to add torque stability, decrease to
improve torque response.
0 to 10000 200ms Programming
Denotes that parameter can be changed when the drive is running. *Menu location is Programming when PI is disabled and Quick Setting when PI is enabled.

S-curve is used to further soften the starting ramp.
The longer the S-curve time, the softer the starting
ramp.
