7. SPECIAL ADJUSTMENT FUNCTIONS
7 - 2
(1) Function
The machine resonance suppression filter is a filter function (notch filter) which decreases the gain of the
specific frequency to suppress the resonance of the mechanical system. You can set the gain decreasing
frequency (notch frequency), gain decreasing depth and width.
