NOTE: Automatic reset is allowed for certain faults only. By giving the parameters M3.10.6 to
M3.10.13 the value 0 or 1 you can either allow or deny the automatic reset after the respective

UMBER OF TRIALS
The Automatic reset function keeps resetting the faults appearing during the time set with this
parameter. If the number of faults during the trial time exceed the value of parameter M3.10.5
a permanent fault is generated. Otherwise the fault is cleared after the trial time has elapsed
and the next fault start the trial time count again.
Parameter M3.10.5 determines the maximum number of automatic fault reset attempts during
the trial time set by this parameter. The time count starts from the first autoreset. The maximum
number is independent of the fault type.
