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