Illegal G/M Code Combination in Block

Hva betyr PS5074 ?

This alarm indicates an error in the NC program block due to invalid G or M code usage. It can be caused by specifying more than three M codes in a single block, using G codes belonging to the same group in one block, or by combining absolute and incremental programming for the same axis when G code system A is active on a lathe system.

• The CNC program contains an invalid combination of G-codes and M-codes that the control system cannot interpret or execute.
• A specific M-code (e.g., M06 for tool change) is being used in a block where a G-code (e.g., G01 for linear interpolation) is not permissible.
• The control's internal logic for sequence verification has detected a conflict between motion commands and miscellaneous function codes.
• The PLC logic or custom macro program has generated a command sequence that violates the machine's programmed syntax rules.

1. 1

   Review the NC program block that triggered the alarm. Ensure that no more than three M codes are specified in a single block.

2. 2

   Inspect the NC program block for G codes. Verify that all G codes belong to different groups; re-program the block if G codes from the same group are found.

3. 3

   If G code system A is in use with a lathe, check the NC program block for simultaneous absolute and incremental programming commands applied to the same axis.
