7 SPECIAL ADJUSTMENT FUNCTIONS
7.1 Filter setting
Shaft resonance suppression filter
This filter is set properly by default according to servo motor you use and load moment of inertia. It is
recommended that [Pr. PB23] be set to "_ _ _ 0" (automatic setting) because changing "Shaft resonance
suppression filter selection" in [Pr. PB23] or [Pr. PB17 Shaft resonance suppression filter] may lower the
performance.
Function
When a load is mounted to the servo motor shaft, resonance by shaft torsion during driving may generate a mechanical
vibration at high frequency. The shaft resonance suppression filter suppresses the vibration.
When you select "Automatic setting", the filter will be set automatically on the basis of the motor you use and the load to servo
motor inertia ratio. The disabled setting increases the response of the servo amplifier for high resonance frequency.
Parameter
Set "Shaft resonance suppression filter selection" in [Pr. PB23].
To set [Pr. PB17 Shaft resonance suppression filter] automatically, select "Automatic setting".
To set [Pr. PB17 Shaft resonance suppression filter] manually, select "Manual setting". The setting values are as follows.
