[Pr. PB17_Shaft resonance suppression filter (NHF)]
Set the shaft resonance suppression filter.
Use this to suppress a high-frequency machine vibration.
When [Pr. PB23.0 Shaft resonance suppression filter selection] is set to "0" (automatic setting), the value will be calculated
automatically from the servo motor used and load to motor inertia ratio. Automatic setting is not carried out when the linear
servo motor is used. When "1" (manual setting) is selected, set the shaft resonance suppression filter with this servo
parameter.
When [Pr. PB23.0] is set to "2" (disabled), this servo parameter setting is disabled. As a result, the filter performance may be
reduced.
When [Pr. PB49.0 Machine resonance suppression filter 4 selection] is set to "1" (enabled), the shaft resonance suppression
filter cannot be used.
