POINT
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 MR Configurator (servo configuration software). This
allows the required notch frequency and depth to be determined.
