The cursor is on the setting of "Input." Press
the or
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 ON the power to the ser-
vomotor. 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
during the measurement.
Within 10 mm, 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
servomotor emits a noise. To ensure safety, do not
enter the working envelope of the motor.
When the detection processing has completed nor-
mally, the result and the notch filter value to be set are
displayed.
Press the Key after the detection to turn OFF the
power to the servomotor.
< Important >
If two 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 stage notch filter has been set, the
second stage notch filter value is displayed. If the
first and second stage 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 processing is not completed nor-
mally, "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.
