Auto Restart (Reset/Run)
The Auto Restart feature provides the ability for 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. Fault types are listed in
descriptions.
Caution should be used when enabling this feature, since the drive will
attempt to issue its own start command based on user selected
programming.
