Sets the gain for the torque compensation function. Use this parameter value for motor 1
when operating multiple motors.
Note:
If A1-02 = 8 [Control Method Selection = EZOLV], you cannot change the setting
while the drive is running.

Torque Ripple Suppress
Min Freq
Adjust this if slow oscillation occurs at low speeds. Increase this parameter in 1.0 Hz
increments when current ripples and torque ripples occur during low-speed operation. Set
this parameter to 0.0 to disable the function if increasing the value does not fix the
problem. Usually it is not necessary to change this setting.
