Drive trip display codes
If the option module detects an error during operation, it will force a trip on the drive.
However, the trip string displayed on the drive will only indicate which slot initiated the
trip. The exact reason for the trip will be indicated in the drive trip code parameters
(Pr
10.020
and Pr
10.070
).
The table below shows the possible trips that will be displayed on the drive when a
problem is detected with the option module or when the option module initiates a trip.
