M2 servo system has advanced anti vibration function which include anti resonance and vibration damping. Anti resonance uses two notch filters to overcome the resonance from the natural mechanical characteristic of the system. Vibration damping uses an adjustable damping ratio in the controller to improve the damping characteristic of the system, which can reduce the vibration of the system.
