11-10 Notch Filters
A notch filter reduces a specified frequency component.
When the machine rigidity is low, factors such as 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 suppresses the
resonance peak to reduce vibration and noise, and allows you to set a high gain.
The 1S-series Servo Drives provide four notch filters for which you can adjust each frequency, width
and depth.
If mechanical resonance occurs, use this notch filter to eliminate resonance.
