31 AUTOMATIC
RESET
Automatic fault reset. Automatic resets are possible only for
certain fault types and when the automatic reset function is
activated for that fault type.
3101 NUMBER OF
TRIALS
Defines the number of automatic fault resets the drive
performs within the time defined by parameter
3102 TRIAL
TIME .
If the number of automatic resets exceeds the set number
(within the trial time), the drive prevents additional automatic
resets and remains stopped. The drive must be reset from
the control panel or from a source selected by parameter
1604 FAULT RESET SEL .
Example: Three faults have occurred during the trial time
defined by parameter 3102 . Last fault is reset only if the
number defined by parameter 3101 is 3 or more.
