7.1.3 Shaft resonance suppression filter
POINT
This filter is set properly by default according to servo motor you use and load
moment of inertia. For [Pr. PB23], "_ _ _ 0" (automatic setting) is recommended
because setting "Shaft resonance suppression filter selection" in [Pr. PB23] or
setting [Pr. PB17 Shaft resonance suppression filter] can degrades in
performance.
(1) 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 motor inertia ratio. The disabled setting increases the response of the servo amplifier for
high resonance frequency.
(2) 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.
