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