7 SPECIAL ADJUSTMENT FUNCTIONS
7.1 Filter setting
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 frequency (notch frequency) at which the gain is
decreased, and the notch depth and width.
You can set five machine resonance suppression filters at most.
Parameter
■
Machine resonance suppression filter 1 ([Pr. PB13] and [Pr. PB14])
Set the notch frequency, notch depth and notch width of the machine resonance suppression filter 1 ([Pr. PB13] and [Pr.
PB14])
When you select "Manual setting (_ _ _ 2)" of "Filter tuning mode selection" in [Pr. PB01], the setting of the machine
resonance suppression filter 1 is enabled.
■
Machine resonance suppression filter 2 ([Pr. PB15] and [Pr. PB16])
To use this filter, select "Enabled (_ _ _ 1)" of "Machine resonance suppression filter 2 selection" in [Pr. PB16].
How to set the machine resonance suppression filter 2 ([Pr. PB15] and [Pr. PB16]) is the same as for the machine resonance
suppression filter 1 ([Pr. PB13] and [Pr. PB14]).
■
Machine resonance suppression filter 3 ([Pr. PB46] and [Pr. PB47])
To use this filter, select "Enabled (_ _ _ 1)" of "Machine resonance suppression filter 3 selection" in [Pr. PB47].
How to set the machine resonance suppression filter 3 ([Pr. PB46] and [Pr. PB47]) is the same as for the machine resonance
suppression filter 1 ([Pr. PB13] and [Pr. PB14]).

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.

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.
