Description
Defines the fault that can be automatically reset using
parameter 31.12 Autoreset
The faults are listed in chapter
Fault code.
Defines the maximum number of automatic resets that the
drive is allowed to attempt within the time specified by
Total trials time.
If the fault persists, subsequent reset attempts will be made at
intervals defined by 31.16 Delay
The faults to be automatically reset are defined by
Autoreset selection.
Number of automatic resets.
Defines a time window for automatic fault resets. The
maximum number of attempts made during any period of this
length is defined by 31.14 Number of
Note: If the fault condition remains and cannot be reset, each
reset attempt will generate an event and start a new time
window. In practice, if the specified number of resets (31.14)
at specified intervals (31.16) take longer than the value of
31.15, the drive will continue to attempt resetting the fault until
the cause is eventually removed.
Time for automatic resets.
Defines the time that the drive will wait after a fault (or a
previous reset attempt) before attempting an automatic reset.
