Preparations

Check the following settings before you execute anti-resonance control adjustment.
• The tuning-less function must be disabled (Pn170 = n.0).
• The test without a motor function must be disabled (Pn00C = n.0).
• The control method must not be set to torque control.
• The parameters must not be write prohibited.

Operating Procedure

To execute anti-resonance control adjustment, an operation reference is input, and the adjust-
ment is executed while vibration is occurring.
The following methods can be used to execute anti-resonance control adjustment.
• To automatically detect the vibration frequency
• To manually set the vibration frequency
Use the following procedure.
 Before you execute anti-resonance control adjustment, check the information provided in
the SigmaWin+ operating manual.
Observe the following precautions.
• Make sure that you can perform an emergency stop at any time.
Parameters will be set automatically when anti-resonance control adjustment is executed. This
may greatly affect the response before and after execution. Make sure that you can perform an
emergency stop (to turn OFF the power supply) at any time.
• Set the moment of inertia correctly before you execute anti-resonance control adjustment.
If the setting greatly differs from the actual moment of inertia, effective vibration reduction may
not be possible.
• If you have already performed anti-resonance control adjustment and then you change the fre-
quency, the current anti-resonance control effect may be lost. Caution is particularly required
when automatically detecting the vibration frequency.
• If effective vibration reduction is not achieved even after you execute anti-resonance control
adjustment, cancel the function and lower the control gain by using a different method, such as
custom tuning.
• Perform custom tuning separately if required to increase the response after performing anti-reso-
nance control adjustment.
If the servo gain is increased, e.g., when custom tuning is performed, vibration may occur again.
If that occurs, perform anti-resonance control adjustment again to fine-tune the parameters.
1.
Perform steps 1 to 7 of the procedure for custom tuning.
For details, refer to the manual for your SERVOPACK.
