Safety

  • Refer to Siemens documentation
  • Ensure qualified technician performs repairs

Causes and Fixes

  1. 1

    Identify the exact machine data or parameter being accessed in the NC program or PLC code at the time of alarm. Check the alarm detail buffer for the specific MD number.

  2. 2

    Review Siemens documentation for the identified machine data to confirm it is a reset-only parameter. Check SINUMERIK 840D parameter manual for bit definitions.

  3. 3

    Modify the program logic to use RESET command instead of SET, or remove the SET instruction entirely if clearing the bit is the intended action.

    Ensure you understand the function of the machine data before modifying - some parameters affect critical system behavior.

  4. 4

    Test the modified program in single block mode to verify the alarm no longer occurs and the intended function is achieved.
