Automatically Clearing Faults
Auto Restart (Reset/Run)
The Auto Restart feature allows the drive to automatically perform a
fault reset followed by a start attempt without user or application
intervention. This allows remote or “unattended” operation. Only certain
faults are allowed to be reset. Certain faults (Type 2) that indicate
possible drive component malfunction are not resettable.
Caution should be used when enabling this feature, since the drive will
attempt to issue its own start command based on user selected
programming.
