10-7 Notch Filter
When the machine rigidity is low, axis torsion may produce resonance which results in vibration
and noise. Thus you may not be able to set a high gain.
The notch filter can restrict the resonance peak, and allows a high gain setting and vibration
reduction.
The OMNUG G5-series Servo Drives provide four notch filters that can be used for adjusting
frequency, width and depth.
If the ball screw, etc. cause resonation at the specific location, you can set the resonance
frequency using a notch filter to eliminate resonance.
A notch filter is used to eliminate a specified frequency component.
If machine resonance occurs, use this notch filter to eliminate resonance.
