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