(2) Operating Procedure
Use the following procedure.
Step Display after Operation Keys Operation
1
Press the Key to view the main menu for the
utility function.
Use the
or Key to move through the list and
select Fn206.
2
Press the Key. The display changes to the Fn206
execution display.
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 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
during the measurement.
Within 10 mm, the servomotor will move forward
and then in reverse several times.
Notes:
• Press the
Key to cancel the measurement. The
servomotor stops moving and the power turns OFF.
The detection of the resonance frequency is not
completed.
• The actions of the servomotor are very minute in
this operation. Also at the same time, the servomo-
tor emits a noise. To ensure safety, do not enter the
working envelope of the motor.
