7. SPECIAL ADJUSTMENT FUNCTIONS
7 - 3
(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.

Machine resonance
suppression filter 1 PB01/PB13/PB14 The filter can be set automatically with
"Filter tuning mode selection" in [Pr.
PB01]. PB13 PB01/PB13/PB14
Machine resonance
suppression filter 2 PB15/PB16 PB15 PB15/PB16
Machine resonance
suppression filter 3 PB46/PB47 PB47
Machine resonance
suppression filter 4 PB48/PB49 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. PB48/PB49
Machine resonance
suppression filter 5 PB50/PB51 Enabling the robust filter disables the
machine resonance suppression filter 5.
The robust filter is disabled for the initial
setting. PB51
