7. SPECIAL ADJUSTMENT FUNCTIONS
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.
The vibration of three resonance frequency can be suppressed by the machine resonance suppression
filter 1, machine resonance suppression filter 2 and machine resonance suppression filter 3.
