Vibration failure prediction [G] [WG]
When a threshold is inputted to the servo amplifier, the servo amplifier starts vibration failure prediction. During the vibration
failure prediction, if the vibration level during servo motor operation, which is estimated by the vibration estimation function,
exceeds the threshold, [AL. 0F7.1 Vibration failure prediction warning] occurs. After the occurrence of [AL. 0F7.1 Vibration
failure prediction warning], if the vibration level during servo motor operation is lower than the threshold, [AL. 0F7.1 Vibration
failure prediction warning] is canceled.
