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.
The hybrid vibration suppression function can be used in the following situations.
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 UsePrecautions 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.

Conditions
Operating mode Fully-closed Control mode
Others • When Servo is ON.
• When elements other than control parameters, such as the torque limit, are set correctly
and there is no trouble with the motor's normal rotation.
