Review the program block flagged in the alarm display. Identify if both ,C or ,R and ,Q parameters are present in the same G01 line.

Remove the taper command (,Q or ,Qn) from the block if chamfer/corner R is required, or remove the ,C or ,R command if taper cutting is required. These operations cannot coexist in a single block.

If both operations are needed, split into separate sequential blocks: execute the tapered move first in one block, then program the chamfer or corner rounding in the following block.

Reset the alarm with RESET button, restart the program from a safe position, and verify proper execution without alarm recurrence.

Access MDI/EDIT mode and navigate to the program line generating the alarm. Press SYSTEM > CURRENT screen to view the actual executed block syntax if using macro variables.

Check macro variables #100-#199 (common local variables) or #500-#999 (common variables) if they control ,C, ,R, or ,Q values. Verify logic prevents simultaneous assignment.

Modify the macro program to include conditional branching (IF-THEN-GOTO statements) that ensures ,C or ,R commands and ,Q commands are never output in the same block.

Dry run the program using SINGLE BLOCK and MACHINE LOCK to verify corrected macro output produces valid G-code blocks.

Ensure MACHINE LOCK (parameter 3003#3=1) is active during verification to prevent unintended machine movement.

Examine the posted G-code from the CAM system. Search for blocks containing both ,C or ,R AND ,Q parameters using a text editor with find function.

Contact the CAM software vendor or review post-processor configuration settings to ensure chamfer/corner rounding and taper operations are designated as mutually exclusive in the post logic.

As a temporary workaround, manually edit the posted G-code to separate conflicting commands into sequential blocks, ensuring geometric intent is preserved.
