Important: Parameters 14 and 85 require two-wire control to allow an
auto restart sequence to occur. 1336VT two-wire control requires that
Logic Interface Option L1, L2 or L3 be installed in the drive.
With the exception of F13-F18 and F33, this parameter sets the number of
times the drive will attempt to restart after a drive fault occurs. Drive
restart attempts may be programmed from 0-9, but must be enabled by
setting Parameter 14 to 1 (on).
When a fault occurs, an internal counter in drive logic is set to Restart
Tries. Two timers will then start –– A 20 second restart time delay and a 4
minute restart period.
When a fault occurs, the 20 second timer is started. When the 20 second
delay is complete, an attempt to clear the fault is made. The internal
counter is decremented 1 restart attempt, while the 4 minute period is
decremented for the total restart time taken.
If the fault clears, the drive will restart. If more faults occur or the same
fault reoccurs before the 4 minute timer expires, the 20 second timer is
reset and the drive will again attempt to clear the fault.
This process will continue for the number of restart tries programmed until
the 4 minute period expires. Once expired, fault F33 (Retries Exceeded)
will occur and the drive must be reset manually.
