The cursor is on the setting of "Input." Press
the

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.

Press the

Key to turn the servomotor power ON.

The display “BB” and “Setting” changes to “RUN”

and “Ready.”

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.

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.
