17. APPLICATION OF FUNCTIONS
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.
You can set five machine resonance suppression filters at most.
Filter
Machine resonance PB01/PB13/PB14
suppression filter 1
Machine resonance PB15/PB16
suppression filter 2
Machine resonance PX17/PX18
suppression filter 3
Machine resonance PX19/PX20
suppression filter 4
Machine resonance PX21/PX22
suppression filter 5
Notch frequency
Setting parameter
The filter can be set automatically with
"Filter tuning mode selection" in [Pr.
PB01].
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.
Enabling the robust filter disables the
machine resonance suppression filter 5.
The robust filter is disabled for the initial
setting.
