Identify the exact line number from the alarm display or program cursor position where execution stopped.

Check for common syntax errors: missing spaces between addresses, decimal point errors (e.g., X1.2.3), invalid characters (special symbols where not allowed), or improper use of parentheses in comments.

Verify address letter and number combinations follow proper format (e.g., G01 not G1.0, X10.5 not X10.5.0). Check that all addresses have valid numeric values.

Correct the syntax error, re-verify the corrected line against programming manual specifications, and reset the alarm to test the program.

Review the flagged program line and identify all G-codes and M-codes present. Cross-reference with the Fanuc programming manual for required parameters.

Check for missing feed rate (F) with G01/G02/G03, missing spindle speed (S) when required, or missing coordinate values for motion commands.

Verify no conflicting G-codes from the same group exist on the same line (e.g., G00 and G01, G90 and G91 together inappropriately).

Add missing parameters or separate conflicting commands to different program lines, then reset and test.

Identify the control model and software version from the system configuration screen to determine supported functions.

Check if the program was written for a different control system or contains non-standard addresses (e.g., using an address letter not available on this machine).

Verify that optional functions required by the code (like canned cycles or special G-codes) are enabled via parameters and actually purchased with the control.

Do not modify system parameters without proper documentation and authorization.

Modify the program to use only supported functions for this control, or contact machine builder to verify if additional software options need to be enabled.
