6.4.2 Anti-Resonance Control Adjustment Function Operating Procedure
With this function, an operation reference is sent, and the function is executed while vibration is occurring.
Anti-resonance control adjustment function is performed from the digital operator (option) or SigmaWin+.
The function cannot be performed from the panel operator.
The following methods can be used for the anti-resonance control adjustment function.
• Using anti-resonance control for the first time
• With undetermined vibration frequency
• With determined vibration frequency
• For fine-tuning after adjusting the anti-resonance control
The following describes the operating procedure from the digital operator.
Refer to the 
Σ
-V Series User’s Manual, Operation of Digital Operator (No.: SIEP S800000 55) for basic key 
operations of the digital operator.
(1) Using Anti-Resonance Control for the First Time
 With Undetermined Vibration Frequency
Step Display after Operation Keys Operation
1
Press the   Key to view the main menu for the 
utility function.
Use the   or   Key to move through the list, 
select Fn204.
2
Press the   Key to display the initial setting screen 
for tuning mode.
3
Press the   or   Key and set the tuning mode 
"0."
4
Press the   Key while "Tuning Mode = 0" is dis-
played. The screen shown on the left will appear. The 
detection of vibration frequencies will start and 
"freq" will flash. Return to step 3 if vibration is not 
detected. 
Note: If vibration is not detected even when vibration 
is occurring, lower the vibration detection sen-
sitivity (Pn311). When this parameter is low-
ered, the detection sensitivity will be increased. 
Vibration may not be detected accurately if too 
small value is set.

–
The vibration frequency will be displayed in “freq” if 
vibration is detected.
