ALARM 4998 M-SAF SYSTEM ERROR2 YRC1000

  • Hello, I am attempting to get servos on but I receive this alarm in the process:

    "If the sub-code 1nxx is displayed..." My sub code is 2101 so I am unsure how to proceed.


    Any help would be appreciated.

  • This has been solved.

    The FSU was configured to use the ASF02 expansion board however that board was not actually installed in the cabinet. Setting the Safety IO board to "Not use" fixed the issue.

  • In Maintenance mode. In Safety security level. SYSTEM, SETUP, OPTION FUNCTION, SAFETY I/O BOARD. Press SELECT on DETAIL. In this screen it will display NOT USE if no board is being used or ASF02 if using the board.

    I know a thing or two, because I’ve seen a thing or two. Don't even ask about a third thing. I won't know it.
