11-10 Hybrid Vibration Suppression Function

This function suppresses the vibration that is caused by the amount of the torsion between the
motor and the load in the Fully-closed Control Mode. You can use this function to increase the
gain setting.

Operating Procedure

1. Set the Hybrid Vibration Suppression Gain (3634 hex) to the same value as the
position loop gain.
2. Gradually increase the set value of the Hybrid Vibration Suppression Filter (3635
hex) while driving with fully-closed control and check the changes in the response.
If the response improves, find the combination of 3634 hex and 3635 hex that result in the
optimal response by adjusting them.
Precautions for Correct Use
This function is effective when the amount of torsion between the motor shaft and the load is large.
It may be less effective when the amount of torsion is small.
