RUN
Torque Compensation
Gain
Sets the gain for the torque compensation function. Use this parameter value for motor
1 when operating multiple motors.
Note:
When A1-02 = 8 [Control Method Selection = EZOLV], you cannot change this
parameter during drive run.

Torque Compensation
Delay Time
Sets the torque compensation delay time. Usually it is not necessary to change this
setting.
Note:
When A1-02 = 5, 8 [Control Method Selection = OLV/PM,EZOLV], you cannot
change the setting while the drive is running.
