8.9 Anti-resonance Control Adjustment

8.9.3 Operating Procedure

8.9.3

Operating Procedure

To adjust anti-resonance control, an operation reference is input, and the adjustment is exe-
cuted while vibration is occurring.
The following methods can be used to adjust anti-resonance control.
• To automatically detect the vibration frequency
• To manually set the vibration frequency
Use the following procedure to perform anti-resonance control.
1.
Perform steps 1 to 8 of the procedure for custom tuning. Refer to the following section
for details.
2.
Click the Anti-res Ctrl Adj Button.
The rest of the procedure depends on whether you know the vibration frequency.

 Before you adjust anti-resonance control, 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 is adjusted. 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 adjust anti-resonance control.
If the setting greatly differs from the actual moment of inertia, effective vibration reduction may
not be possible.
• If you have already adjusted anti-resonance control and then you change the frequency, the cur-
rent 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 adjust anti-resonance control, can-
cel 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 adjusting anti-reso-
nance control.
If the servo gain is increased, e.g., when custom tuning is performed, vibration may occur again.
If that occurs, adjust anti-resonance control again to fine-tune the parameters.
