RUN
Torque Compensation Gain
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.

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 [Control Method Selection = OLV/PM], you cannot change the setting while
the drive is running.
• When A1-02 = 8 [EZOLV], you cannot change the setting while the drive is running.

Torque Ripple Suppress Min
Freq
If there is slow oscillation at low speeds, adjust this setting. Usually it is not necessary to change this
setting.
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.
Note:
Set C4-20 [Voltage Compensation Adjust 1] ≠ 0 to enable this parameter.
