13.4 Utility Function (Fn
) Operations on the Panel Operator
13.4.31 Adjust Anti-resonance Control (Fn204)
13-32
13.4.31 Adjust Anti-resonance Control (Fn204)
This function cannot be executed from the Panel Operator on the SERVOPACK.
13.4.32 Vibration Suppression (Fn205)
This function cannot be executed from the Panel Operator on the SERVOPACK.
13.4.33 Easy FFT (Fn206)
Refer to the following section for information on this utility function other than the procedure.

Keys
Operation
1
Press the
MODE/SET
Key to enter Utility Function
Mode.
2
Press the
UP
Key or
DOWN
Key to display
Fn206
.
3
(Reference amplitude
setting)
Press the
DATA/SHIFT
Key for approximately one sec-
ond. The display shown on the left will appear and the
Panel Operator will enter Reference Amplitude Setting
Mode.
4
Press the
UP
Key or
DOWN
Key to set the reference
amplitude. Reference amplitude setting range: 1 to 800
Note: 1. If you are setting Easy FFT for the first time, do not
change the reference amplitude setting, but rather
start from the default value of 15. Although increasing
the reference amplitude will increase the detection
accuracy, the vibration and noise in the machine will
increase momentarily. Increase the reference ampli-
tude a little at a time and observe the results.
2. The set reference amplitude will be stored in Pn456.
5
(Ready to operate sta-
tus)
Press the
DATA/SHIFT
Key for approximately one sec-
ond. The ready to operate status will be entered.
6
Press the
MODE/SET
Key to turn ON the servo.
Additional Information
Press the
MODE/SET
Key again to turn OFF the servo.
Return to step 5.
7
(Flashing)
Slight movement in
Servomotor
While the servo is ON, press the
UP
Key (forward) or
the
DOWN
Key (reverse). The Servomotor will auto-
matically perform round-trip operation, moving in for-
ward and reverse several times for 1/4th of a rotation
for a Rotary Servomotor and 10 mm or less for a Linear
Servomotor. The Servomotor performs this operation
for approximately 2 seconds. During this operation, the
display shown on the left will flash.
Note: 1. Press the
MODE/SET
Key to cancel the operation.
Return to step 5.
2. The Servomotor will move slightly. Also at the same
time, the Servomotor will emit noise. To ensure
safety, do not approach or enter the range of
machine motion.
