Reducing P2-08 and increasing P2-12 can
greatly improve the inertia capability, but
it will reduce the responsiveness, which
has a great impact on responsiveness.

Increasing will improve the servo rigidity
and enhance anti-disturbance ability, can

Increasing will improve the inertia
capacity slightly, and has little effect on
the responsiveness, to be an auxiliary
parameter.

6.7 Vibration suppression
6.7.1 Overview
The mechanical system has a certain resonance frequency. When the servo gain is increased, the
continuous vibration may occur near the resonance frequency of the mechanical system. Generally in
the range of 400Hz to 1000Hz, it caused the gain can not continue to increase. Vibration can be
eliminated by automatically detecting or manually setting the vibration frequency. After the vibration is
eliminated, if the responsiveness needs to be improved, the gain can be further improved.
Note:
(1) Servo responsiveness will change after vibration suppression operation.
(2) Before performing the vibration suppression operation, please set the inertia ratio and gain
parameters correctly, otherwise it can not be controlled properly.
