Selection No.
From source selected by parameter 31.9 External event
5 source
External fault 5 b15
1 = 1 0000h…FFFFh
0 / uint32 Defines the fault that can be automatically reset using
parameter
31.12 Autoreset selection , bit 10.
The faults are listed in chapter Fault tracing (page 649) .
User selectable fault 31.13
1 = 1 Fault code. 0000…FFFFh
0 / uint32 Defines 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 trials 31.14
1 = 1 / 1 = 1 Number of automatic resets. 0...5
30.0 s / real32 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 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 time 31.15
10 = 1 s / 10 = 1 s Time for automatic resets. 1.0 ... 600.0 s
0.0 s / real32 Defines 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 time 31.16
10 = 1 s / 10 = 1 s Autoreset delay. 0.0 ... 120.0 s
Fault / uint16 Selects 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.
Motor phase loss 31.19
0 No action taken. No action
1 The drive trips on fault 3381 Output phase loss . Fault
Fault / uint16 Selects how the drive reacts when an earth fault or
current unbalance is detected in the motor or the motor
cable.

Earth fault 31.20
0 No action taken. No action
1 The drive generates an A2B3 Earth leakage warning. Warning
