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.

Parameter Descriptions

ENABLE

Range: FALSE / TRUE

Enables operation of the auto restart feature.

ATTEMPTS

Range: 1 to 10

Determines the number of restarts that will be permitted before requiring an external fault

reset.

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

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 and 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 codes.

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

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 and 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 codes.
