ence 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
The display "BB" and "Setting" changes to "RUN"
and "Ready."
Press the
(reverse run start) Key to run the servomotor and start
the frequency measurement. "Measure" is displayed
during the measurement.
Within a quarter turn, the servomotor will move for-
ward and then in reverse several times.
Notes:
• Press 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.
