7.1.1 Machine resonance suppression filter
POINT
The machine resonance suppression filter is a delay factor for the servo system.
Therefore, vibration may increase if you set an incorrect resonance frequency or
set notch characteristics too deep or too wide.
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.
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 MR Configurator2. This allows the required notch frequency and notch
characteristics to be determined.
If a mechanical system has a natural resonance point, increasing the servo system response level may
cause the mechanical system to produce resonance (vibration or unusual noise) at that resonance
frequency. Using the machine resonance suppression filter and adaptive tuning can suppress the resonance
of the mechanical system. The setting range is 10 Hz to 4500 Hz.
