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.
