PB17 Set the shaft resonance suppression filter.
NHF Use this to suppress a low-frequency machine vibration.
Shaft When you select "Automatic setting (_ _ _ 0)" of "Shaft resonance suppression filter selection" in [Pr.
resonance PB23], the value will be calculated automatically from the servo motor you use and load to motor inertia
suppression ratio. It will not be automatically calculated for the linear servo motor. Set manually for "Manual setting
filter (_ _ _ 1)".
When "Shaft resonance suppression filter selection" is set to "Disabled (_ _ _ 2)" in [Pr. PB23], the
setting value of this parameter will be disabled.
When "Machine resonance suppression filter 4 selection" is set to "Enabled (_ _ _ 1)" in [Pr. PB49], the
shaft resonance suppression filter is not available.
When "Shaft resonance suppression filter selection" is set to "Disabled (_ _ _ 2)" in [Pr. PB23], the
performance may be reduced.
