9.15.2 Easy FFT
The machine is made to vibrate and a resonance frequency is detected from the gener-
ated vibration to set notch filters according to the detected resonance frequencies. This is
used to eliminate high-frequency vibration and noise.
During execution of Easy FFT, a frequency waveform reference is sent from the SERVO-
PACK to the Servomotor to automatically cause the shaft to rotate multiple times within
1/4th of a rotation, thus causing the machine to vibrate.
Execute Easy FFT after the servo is turned OFF if operation of the SERVOPACK results
in highfrequency noise and vibration.
WARNING!
Never touch the Servomotor or machine during execution of Easy FFT.
Doing so may result in injury.
