Eliminating the cause for TRIP error message
After eliminating the cause for a TRIP error message the error message must be reset with the “TRIP
reset” order. Only then the drive will start again.
)
Manual or automatic TRIP reset
You can select whether errors occurred are to be reset manually or automatically. Mains
disconnection always carries out a TRIP reset independent of the settings under C0170.

Troubleshooting and fault elimination
Note!
A TRIP error message can have several causes. The TRIP reset can only be carried
out after all causes for the TRIP have been eliminated.
Note!
If the controller carries out more than eight automatic TRIP resets within ten
minutes, the controller will set TRIP rST (Counter exceeded).
TRIP reset also resets the auto TRIP counter.
