cuting this function or of being changed automatically after executing this function.
• Parameters related to this function
These are parameters that are used or referenced when executing this function.
• Allowed changes during execution of this function
Yes : Parameters can be changed using SigmaWin+ while this function is being executed.
No : Parameters cannot be changed using SigmaWin+ while this function is being executed.

To exit the EasyFFT function at this stage, press
the
Key. The power to the servomotor is turned
OFF and the display returns to the main menu of the
utility function.
To remeasure the vibration frequency, press
the
Key to return to step 4. Execute steps 5 to 7.
8
Press the Key after the normal completion of
frequency detection. The notch filter frequencies are
automatically updated to the optimum values.
The status display shows "DONE" and the display
shown on the left appears.
If the first stage notch filter frequency has been set
(Pn408.0 = 1), the second stage notch filter frequency
(Pn 40C) will automatically be updated.
Notes:
• If the first stage or the second stage notch filter fre-
quency has already been set (Pn408 = n. 1 1),
the notch filter frequency cannot be set.
• If the frequency detected by this function is not
used, set the notch filter to be invalid (Pn408.0 =
0).

Press the Key.
The servomotor enters a baseblocked status. The dis-
play returns to the main menu of the utility function.
10 To enable the change in the setting, restart the SERVOPACK.
