1 = 10000h…FFFFh
0 / uint32Defines the fault that can be automatically reset using
parameter 31.12 Autoreset selection, bit 10.
The faults are listed in chapter Fault tracing (page 547).
User selectable fault31.13
1 = 1Fault code.0000…FFFFh
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
10 = 1 s / 10 = 1 sAutoreset delay.0.0 ... 120.0 s
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.
