The machine vibration can sometimes be suppressed by setting a notch filter or force reference filter for the
vibration frequencies.
When online, vibration frequencies caused by machine resonance will be detected and the frequency that has
the highest peak will be displayed on the Panel Operator. The effective force reference filter or notch filter fre-
quency for the vibration frequency will be automatically selected and the related parameters will be automati-
cally set.
