56040000 hex

CNC Multi-execution Disabled

Omron · NJ/NY-series NC Integrated Controller

What does 56040000 hex mean?

This minor fault occurs when multiple CNC functions that cannot run concurrently are attempted for the same target, such as a CNC coordinate system. It is detected at instruction execution within the CNC Function Module, affecting CNC common or a specific CNC coordinate system. The relevant instruction will not execute, and the CNC coordinate system will stop immediately if it is moving.

Common Causes

  • Multiple CNC instructions, specified as non-simultaneously executable, were triggered for the same CNC coordinate system.
  • The `CNC_LoadProgramFile` instruction was executed while any CNC coordinate system was in an `Executing` or `Hold` state.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Review the CNC program to identify instances where multiple instructions are executed simultaneously targeting the same CNC coordinate system.

  2. 2

    Consult the instruction specifications to determine which instructions cannot be executed concurrently.

  3. 3

    Modify the program logic to ensure that instructions identified as non-concurrent are not executed at the same time for the same CNC coordinate system.
