Second Processor Run-time Error Codes
If the Second Processor detects an error during operation the error code will be placed
in the following parameter:
For certain errors the user may select if the drive should trip as well. This is configured
with the Global Run-time Trip enable parameter:
If set to 1 (On), the drive will trip on ALL run-time errors.
The table below shows the error codes and their meaning as well as if the drive will trip,
the User program will stop and whether the DPL ERROR task will run.
Notes:
•
“May”
under Drive Trip indicates that the drive will only trip if the global run-time trip
enable parameter is set
•
“Not Run”
under Program Halted indicates that the error occurs at Initialization and
the program will not be started.
