Shaft Resonance Suppression Filter - Mitsubishi Electric MELSERVO-JE MR-JE-70A 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 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.
