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.

suppression filter 1
The filter can be set automatically with
"Filter tuning mode selection" in [Pr.
PB01].

suppression filter 3
Machine resonance
suppression filter 4
Enabling the machine resonance
suppression filter 4 disables the shaft
resonance suppression filter.
Using the shaft resonance suppression
filter is recommended because it is
adjusted properly depending on the
usage situation.
The shaft resonance suppression filter is
enabled for the initial setting.
Machine resonance
suppression filter 5
Enabling the robust filter disables the
machine resonance suppression filter 5.
The robust filter is disabled for the initial
setting.
