Keys
When the detection has completed normally, the
result and the notch filter value to be set are dis-
played.
Press the
servomotor.
< Important >
If 2 seconds or more are required for the operation
although detection was successfully 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 notch filter has been set, the second
notch filter value is displayed. If the first and
second notch filters have been set, only the result
of frequency detection is displayed.
• If the Key is pressed while the linear servo-
motor is running, the linear servomotor will stop,
and the frequency detection will be canceled.
• If the detection is not completed normally, "No
Measure" is displayed.

Notes:
• If the second notch filter frequency has already
been set (Pn408.2 = 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).
