6.4.1.4 AUTO RESTART
Auto Restart (or Auto Reset)
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. This function is inhibited in
Remote Sequencing Comms mode. MMI Menu Map

Parameter Descriptions Parameter Descriptions
ENABLE ENABLE Range: FALSE / TRUE
Enables operation of the auto restart feature.
ATTEMPTS
ATTEMPTS Range: 1 to 10
Determines the number of restarts that will be permitted before requiring an external
fault reset.
INITIAL DELAY 1
INITIAL DELAY 1 Range: 0.0 to 600.0 s
Determines the delay for the first restart attempt when the trip is included in
TRIGGERS 1 .
The delay is measured from all error conditions clearing.
ATTEMPT DELAY 1
ATTEMPT DELAY 1 Range: 0.0 to 600.0 s
Determines the delay between restart attempts for a trip included in TRIGGERS 1 .
The delay is measured from all error conditions clearing.
TRIGGERS 1
TRIGGERS 1 Range: 0000 to FFFF
Allows Auto Restart to be enabled for a selection of trip conditions.
Refer to “Hexadecimal Representation of Trips” at the beginning of this chapter for an
explanation of the four-digit code.
INITIAL DELAY 2
INITIAL DELAY 2 Range: 0.0 to 600.0 s
Determines the delay for the first restart attempt when the trip is included in
TRIGGERS 2
The delay is measured from all error conditions clearing.
ATTEMPT DELAY 2
ATTEMPT DELAY 2 Range: 0.0 to 600.0 s
Determines the delay between restart attempts for a trip included in TRIGGERS 2 .
The delay is measured from all error conditions clearing.
TRIGGERS 2
TRIGGERS 2 Range: 0000 to FFFF
Allows Auto Restart to be enabled for a selection of trip conditions.
If a trip is included in both TRIGGERS 1 and TRIGGERS 2, then the times associated
with TRIGGERS 1 will take priority.
Refer to “Hexadecimal Representation of Trips” at the beginning of this chapter for an
explanation of the four-digit code.
