The cursor is on the setting of "Input." Press
the
or
Key to set the sweep torque
reference amplitude (Pn456)
Setting range: 1 to 800.
Note:When making the initial settings for EasyFFT,
do not change the setting for the reference
amplitude. Start with the original value of 15.
Increasing reference amplitude increases the
detection accuracy, but the vibration and noise
from the machine will increase. Increase the
amplitude value little by little.
4
Press the
Key to turn the servomotor power ON.
The display “BB” and “Setting” changes to “RUN”
and “Ready.”
5
Press the
(forward run start) Key or
(reverse run start) Key to run the servomotor and start
the frequency measurement. "Measure" is displayed
blinking during the measurement.
Within a quarter turn, the servomotor will move
forward and then in reverse several times. The total
operation time is between 1 and 45 seconds.
Note:The actions of the servomotor are very minute
in this operation. Also at the same time, the ser-
vomotor emits a noise. To ensure safety, do not
enter the working envelope of the motor.

When the detection has completed normally, the
result and the notch filter value to be set are dis-
played.
Press the
Key to turn OFF the power to 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 servomotor is
running, the servomotor will stop, and the fre-
quency detection will be canceled.
• If the detection is not completed normally, “No
Measure” is displayed.
7
Press the
Key to exit the EasyFFT function at
this stage. The power to the servomotor is turned OFF
and the display returns to the Utility Function Mode
main menu.
Press the
Key to return to "Ready" display.
