Altivar 630 automatic reset

[LouD]

If the Altivar 630 faults after a power failure but there was no run command present at time of power failure, will the drive reset once a run command is present such as a call for a lag pump or a pump sequence change?

Hi LouD :
Thanks for your question .

The complete drive will switch off after main power supply loss , then drive will store in the fault history memory USF ( Undervoltage fault) . but  USF is cleared as soon  power supply is recovered  and it will be operable for next run order.

For other hand , ATV630 has  Automatic Restart function(ATR) for other type of faults,. Please refer to the ATV600 programming manual to know more  about this funtion
