Shaft Resonance Suppression Filter - Mitsubishi Electric MR-J4W2-0303B6 Instruction Manual

7. SPECIAL ADJUSTMENT FUNCTIONS

7.1.3 Shaft resonance suppression filter

(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 servo 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.
POINT
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.
