DescriptionName / Range /
Selection
No.
0 / uint32Defines the maximum number of automatic resets that the
drive is allowed to attempt within the time specified by
31.15 Total trials time.
If the fault persists, subsequent reset attempts will be made
at intervals defined by 31.16 Delay time.
The faults to be automatically reset are defined by 31.12
Autoreset selection.
Number of trials31.14
1 = 1 / 1 = 1Number of automatic resets.0...5
30.0 s / real32Defines 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 trials.
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.
Total trials time31.15
10 = 1 s / 10 = 1 sTime for automatic resets.1.0 ... 600.0 s
0.0 s / real32Defines the time that the drive will wait after a fault (or a
previous reset attempt) before attempting an automatic
reset.
See parameter 31.12 Autoreset selection.
Delay time31.16

Fault / uint16Selects how the drive reacts when a motor phase loss is
detected.
Note: The drive may not be able to reliably detect a phase
loss in a multimotor application: a separate protection
method (eg. a motor protection switch) should be installed
for each motor.

Fault / uint16Selects how the drive reacts when an earth fault or current
unbalance is detected in the motor or the motor cable.
