Power section error auxiliary voltage supply
The auxiliary voltage supply is monitored and generates an error message if undervoltage occurs. The error is fatal and leads to immediate shutoff of the drive controller. In this case the drive coasts to a standstill. Renewed release of the drive by the controller is prevented until the cause of the error has been corrected and the error has been acknowledged. The error can be acknowledged at the control centre after the cause of the error has been corrected.
