Torque Compensation
C4-01
0215
Torque Compensation
Gain
Torq Comp Gain
This parameter helps to produce better starting torque. It determines the
amount of torque or voltage boost based upon motor current and motor
resistance.

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.

CarrierFreq Sel
Carrier frequency sets the number of pulses per second of the output
voltage waveform.
1: 2.0 kHz
2: 5.1 kHz
3: 8.0 or 7.0* kHz
F: Program (Determined by the setting of C6-03)
* when an option card is installed
Note: In PRG: <0035> C6-02 is default is 2 kHz for all KVA sizes except
when A1-03=7770. Refer to page 40 for setting details.

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