342 Parameters
Autoreset Fault on high priority faults (except STO related faults) with
automatic fault reset and run. See the list of high priority faults
above.
See parameter
70.21 Override auto reset trials .
1
70.21 Override auto reset
trials Defines the number of automatic fault resets the drive
performs during override operation When the parameter is set
to 0, reset trials are made continuously during the override
operation. A value of 1…5 defines a specific number of
automatic reset trials. 5
0...60 Number of automatic reset trials. 1 = 1
70.22 Override auto reset
time Defines the time the drive will wait after a fault before
attempting an automatic fault reset. 5.0 s
0.1...120.0 s Auto reset delay time. 10 = 1 s
