5.6.2 Anti-resonance Control Adjustment Function Operating Procedure
With this function, a control 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 following three methods can be used for the anti-resonance control adjustment function. Select and use
the best method.
1. With Undetermined Vibration Frequency Before Adjusting the Anti-resonance Control
2. With Determined Vibration Frequency Before Adjusting the Anti-resonance Control
3. For Fine-tuning After Adjusting the Anti-resonance Control
The operating procedures from the Digital Operator are described here.
Refer to the Σ -V series User’s Manual, Operation of Digital Operator (SIEP S800000 55) for basic key oper-
ations of the Digital Operator.

Step Display after Operation Keys Operation
1
Press the Key to view the main menu for the
utility function mode.
Use the
or Key to move through the list,
select Fn204.
2
Press the Key to display the initial setting screen
for tuning mode.
Note: If the display does not switch and “NO-OP” is
displayed, take corrective action after checking
the items given in 5.6.1 (1) Before Performing
Anti-resonance Control Adjustment Function.
3
Press the or Key and select 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 blink. Return to step 3 if vibration is not
detected.
Note: If a vibration is not detected even though a
vibration has occurred, lower the vibration
detection sensibility (Pn311). When this
parameter is lowered, the detection sensitivity
will be increased. Vibration may not be
detected accurately if too small value is set.
5
The vibration frequency will be displayed if vibration
is detected.
