Parameter Name No.
AR Restart Pending 1508
Indicates that the AR feature will reset the trip source and attempt to restart the motor once all trips have become inactive and the
relevant delay timer has expired.
AR Restarts Remaining 1509
Indicates the number of restart attempts remaining before the AR feature disables itself.
This count is reset to 1471 AR Max Restarts after a successful manual or remote trip reset. The count is also reset after a period of
trip free operation. This period is the longer of 5 minutes, or 5 * AR Repeat Delay B.
AR Time Remaining 1510
Indicates the time remaining before a restart attempt will be made. This value starts to count down once all trip sources are inactive.
Functional Description
The AR feature can be configured to operate in one of three modes via the parameter 1470 AR Mode.
In all modes the AR feature becomes active when the drive trips on one of the trips selected by parameter 1472 AR Trip Mask. If the drive trips due
to a trip not selected in 1472 AR Trip Mask the AR feature will remain in the idle state.
Setting parameter 1469 AR Enable to FALSE will disable the AR feature regardless of its current state.
1470 AR Mode 0: Trip Reset
In Trip Reset mode, once the AR feature becomes active it monitors all possible trip sources. Once all trip sources are inactive the AR feature will
attempt to reset the trip event, moving the Sequencing State from the FAULTED state, (see Appendix B: Sequencing Logic). The AR feature resets
the trip as soon as possible, it does not wait for either 1505 Initial Delay or 1506 AR Repeat Delay.
In this mode the AR feature will not attempt to restart the motor.
This mode may be used when an external supervisiory system is monitoring the Faulted bit in 0661 Status Word. This bit will be cleared once all trip
sources are inactive and the trip has been successfully cleared, indicating that the drive may be started.
