Triggering a user-defined fault
The "User-defined fault 1" and "User-defined fault 2" functions serve to set the inverter from
the process to the error status.
Details
If, for instance, sensors or switches are provided for process monitoring, which are designed
to stop the process (and thus the drive) under certain conditions, these sensors/switches can
be connected to free digital inputs of the inverter. The digital inputs used for the sensors/
switches then have to be assigned to the error triggering functions as triggers.
Parameter
Name / value range / [default setting]

(PAR 400/043)
Function assignment: User-defined fault 1

Assignment of a trigger for the "User-defined fault 1" function.
Trigger = TRUE: trigger user-defined fault 1.
Trigger = FALSE: no action.
Notes:
•
When the fault has been triggered, the inverter changes to the "Trou-
ble" state.
•
After resetting the fault, a new enable/start command is required to
restart the drive.
00 Not connected
No trigger assigned (trigger is constantly FALSE).
