Overview

This section provides basic diagnostic information intended to resolve the most common problems
encountered when setting up an SI-Universal Encoder option module.
9.1.1 Drive trip display codes
If the option module detects an error during operation, it will force a trip on the drive. The exact
reason for the trip will be logged in the drive trip log (Pr 10.020 to Pr 10.029).
Table 9-1 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.

communicate with it due to a hardware fault.
User trip generated by the option module
This trip will occur if a drive slot was previously configured with an option
module but on power up, no option module was detected.
This trip will occur if a drive slot was previously configured with an option
module but on power up, a different option module was detected. Replacing
the option module with another one of the same ID number will not initiate this
trip.
The trip will also occur if an option module is installed to a previously un-used
slot.
