Parameters 281
31.42 Overcurrent fault
limit
Sets a custom motor current fault limit.
The drive automatically sets an internal motor current limit
according to the drive hardware. The internal limit is
appropriate in most cases, but this parameter can be used to
set a lower current limit, for example, to protect a permanent
magnet motor from demagnetization.
Note: The limit defines the maximum peak current of one
phase.
With this parameter at 0.0 A, only the internal limit is in force.
0.00 A
0.00 … 30000.00 A Custom motor current fault limit. See par.
46.05
31.54 Fault action Selects the stop mode when a non-critical fault occurs. Coast
Coast The drive coasts to a stop. 0
Emergency ramp The drive follows the ramp specified for an emergency stop in
parameter 23.23 Emergency stop time.
1
31.55 Ext I/O comm loss
event
Selects how the drive reacts when the communication to an
I/O extension module fails.
Fault
No action No action taken. 0
Warning The drive generates a warning, A799 Ext I/O comm loss.1
Fault The drive trips on a fault, 7082 Ext I/O comm loss.2
31.120 LSU earth fault (Only visible when IGBT supply unit control activated by
95.20)

31.121 LSU supply phase
loss
(Only visible when IGBT supply unit control activated by
95.20)
