Unique Instantaneous Mains Failure Reaction Upon the instantaneous mains failure, the energy of the motor feedback bus will keep the Asynchronous servo drive running till the mains resumes normal. When shutdown is caused by long-term power-failure during the operation of the Asynchronous servo drive, the Asynchronous servo drive will provide alarm message after power resumes normal. It supports the automatic operation after power-up. The deceleration time during the power failure and the acceleration time after the power recovery can be set independently. It is especially suitable for: Instantaneous...
