7.16 Online Vibration Monitoring (Fn402)
7.16.1 Overview
When the servo is ON and vibration occurs during operation, this operation can set the notch filter
1 or the torque command filter according to the vibration frequency, sometimes eliminating the
vibration. Detect the vibration frequency of noise caused by mechanical resonance and display the
vibration frequency with large peak on the operator. The effective torque command filter or notch
filter 1 frequency for the vibration frequency will be automatically selected and the related
parameters are automatically set.
When using the PC debugging software to adjust, it is recommended to perform the smart setting
or bandwidth setting. Generally, no manual operation is required. Only when the PC debugging
software is not available, it is key-assisted.
