10-10 Hybrid Vibration Suppression Function
This function suppresses the vibrations that are caused by the amount of the torsion between
the motor and the load in the FULL CLOSING CONTROL mode.You can use this function to
raise the gain setting.
Operating Conditions
The hybrid vibration suppression function can be used in the following situations.
Parameters Requiring Settings
Operating Procedure
1. Set the Hybrid Vibration Suppression Gain (Pn634) to the same value as the position
loop gain.
2. Gradually increase the set value of the Hybrid Vibration Suppression Filter (Pn635)
while driving with full closing control and check the changes in the response.
If the response improves, find the combination of Pn634 and Pn635 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.This may be less effective when the amount of torsion is small.
Conditions
Operating mode FULL CLOSING CONTROL mode
Others
• Servo-ON state.
• The factors other than control parameters are set correctly. This includes the
torque limit. The motor operates normally without any failures.
