- 1
Review the NC program and PMC ladder logic for any sequences that could lead to an invalid or unexpected command execution.
- 2
Check for any conditional logic (e.g., IF statements, GOTO commands) that might lead to an unintended program flow.
- 3
Verify the machine's current operational mode and state transitions (e.g., manual to auto, program restart) for any irregularities.
- 4
Examine any recently modified programs or macros for logical errors or unsupported commands.
- 5
Perform a step-by-step execution of the program in single-block mode to pinpoint the exact point of the illegal sequence.
