AC890PX AC Drive
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.
Parameter Descriptions
ENABLE
PREF: 93.01 Default: FALSE Range: FALSE / TRUE
Enables operation of the auto restart feature. TRUE = enabled.
ATTEMPTS PREF: 93.02 Default: 5 Range: 1 to 10
Determines the number of restarts that will be permitted before requiring an external fault reset.
INITIAL DELAY 1 PREF: 93.03 Default: —.x s Range: 0.0 to 600.0 s
Determines the delay for the first restart attempt when the trip is included in TRIGGER 1 WORD 1.
The delay is measured from all error conditions clearing.
ATTEMPT DELAY 1 PREF: 93.04 Default: —.x s Range: 0.0 to 600.0 s
Determines the delay between restart attempts for a trip included in TRIGGER 1 WORD 1. The delay is measured from all error conditions clearing.
TRIGGER 1 WORD 1 to
TRIGGER 1 WORD 6 PREF:93.05, 93.06, 93.15, 93.16,
93.19, 93.20 Default: 0000 Range: 0x0000 to 0xFFFF
Allows Auto Restart to be enabled for a selection of trip conditions. Refer to TRIPS STATUS, page D-159, for an explanation of the four-digit
