PNO Parameter Descriptions
1507
AR Active
Indicates that the AR feature will reset the trip source once all trips have become inactive, (following a delay time if the AR feature
has been configured to also restart the motor).
1508
AR Restart Pending
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.
1509
AR Restarts Remaining
Indicates the number of restart attempts remaining before the AR feature disables itself.
This count is reset to 1471 AR Max Restarts following 5 minutes of trip free operation, or after a successful manual or remote trip
reset.
1510
AR Time Remaining
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:
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.
1470 AR Mode 1:
Caution: when Auto Restart is selected the motor may run unexpectedly.
In Auto Restart mode, once the AR feature becomes active it monitors all possible trip sources. Once all trip sources are inactive the AR feature
starts the programmed delay. Once the delay timer expires the AR feature attempts to reset the trip and to restart the motor.
The AR feature will not restart the motor if it was not running at the time of the trip, nor will it restart the motor if the run signal has been removed
at any time since the trip, (even if it is subsequently re-applied). When a motor restart will not be attempted the AR feature will act as if it had
been configured for Trip Reset only. If a motor restart will be attempted the parameter 1508 AR Restart Pending is set TRUE.
Each time a restart is attempted the value in 1509 Restarts Remaining is decremented. Once this value reaches zero, any further trip selected
for auto restart will cause the AR feature to disable itself.
