AUTO RESTART
SETUP::SEQ & REF::AUTO RESTART
Auto Restart provides the facility to automatically reset a choice of trip events and restart the Drive with a programmed
number of attempts, after which, a manual or remote trip reset is required if the Drive is not successfully restarted. The number
of attempted restarts are recorded. This count is cleared after a trip-free period of operation (5 minutes or 4 x ATTEMPT
DELAY 1, whichever is the longer), or after a successful manual or remote trip reset, or by removing the Run signal, or by
setting the ENABLE input to this block FALSE.
