NOTES
If the frequency of machine resonance is unknown, decrease the notch frequency from
higher to lower ones in order. The optimum notch frequency is set at the point where
vibration is minimal.
A deeper notch has a higher effect on machine resonance suppression but increases a
phase delay and may increase vibration.
The machine characteristic can be grasped beforehand by the machine analyzer on the
setup software). This allows the required notch frequency and attenuation to be determined.
