7.2.3 Machine resonance suppression filter
(1) Function
The machine resonance suppression filter is a filter function (notch filter) which can suppress the resonance
of the mechanical system by decreasing the gain of the specific frequency. You can set the gain decreasing
frequency (notch frequency), gain decreasing depth and width.
