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