Vibration estimation function
The vibration estimation function monitors torque vibrations to estimate high-frequency, minute vibration levels and vibration
frequencies. An increase in the vibration level and a change in the vibration frequency due to excess play or deterioration in
guides, ball screws, and belts can be observed.
The vibration estimation function estimates the vibration level and vibration frequency respectively during servo motor
operation and at a servo motor stop. Vibration levels and frequencies during servo motor operation and during servo motor
stop are estimated separately.
