When the detection processing is success-
fully completed, "Measure" stops flashing
and the results and the notch filter value to
be set are displayed. If the processing was
not completed, "No Measure" is displayed.
To check the results, go to step 8.
< Important >
If two seconds or more are required for the
operation although detection was success-
fully completed, the detection accuracy
might be insufficient. Increasing reference
amplitude more than 15 increases the
detection accuracy, but the vibration and
noise from the machine will increase.
Increase the amplitude value little by little.
Notes:
• If a notch filter has been set and is being
used, "*" is displayed on the second
line.
• If the first stage notch filter has been set,
the second stage notch filter value is dis-
played. If the first and second stage
notch filters have been set, only the
result of frequency detection is dis-
played.
To exit the EasyFFT function at this stage,
press the
vomotor is turned OFF and the display
returns to the utility function mode main

pletion 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 auto-
matically be updated.
Notes:
• If the first stage or the second stage
notch filter frequency has already been
set (Pn408 = n. 1 1), the notch filter
frequency cannot be set.
• If the frequency detected by this func-
tion is not used, set the notch filter to be
invalid (Pn408.0 = 0).
