(1) Operating Procedure
Follow the steps below.
Step
Display Example
Keys
Operation
1
Press the
Key to view the main menu for the util-
ity function mode.
Use the
or
Key to move through the list,
select Fn206.
2
Press the
Key. The display is switched to the
execution display of Fn206.
Note:
If the display is not switched and “NO-OP” is dis-
played in the status display, change the following set-
tings. (Refer to 6.12.)
• If Write Prohibit is set in Fn010:
→ Cancel the Write Prohibited setting.
• If a servo ON command is input:
→ Send a servo OFF command.
3
The cursor is on the setting of "Input." Press
the
or
Key to set the sweep force 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 linear 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 linear servomotor
and start the frequency measurement. "Measure" is
displayed blinking during the measurement.
<Linear Servomotor Movement during Detection>
Within 10 mm, the linear 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 linear servomotor are very minute
in this operation. Also at the same time, the linear ser-
vomotor emits a noise. To ensure safety, do not enter
the working envelopment of the machine.
