6-15 Hybrid Vibration Suppression Function
Outline of Operation
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.
The hybrid vibration suppression function can be used in the following situations.
Œ
FULL CLOSING CONTROL mode
Œ
When servo is ON
Œ
When there is no trouble with the motor's normal rotation
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
Œ
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.
