To suppress stationary vibrations such as sympathetic axis vibration, created by Servo axis,
of 400 Hz or higher, use a torque reference notch filter. The following shows parameters
relating to the torque reference notch filter. For further information on the torque reference
notch filter, refer to a separate instruction manual.
