What causes KUKA Robot alarm KRC0877?

Label referenced in GOTO or CALL statement does not exist in the current program scope. Label name is misspelled or contains incorrect syntax in the reference statement. Label was declared in a different module or function but referenced without proper module prefix. Label declaration was accidentally deleted or commented out during program editing. Label is defined in an included file that was not properly loaded or has incorrect syntax.

How do I fix KUKA Robot alarm KRC0877?

1. Review the KRL source code and locate the line number where the undefined label is being referenced 2. Search the entire program file for the label definition to verify it exists and matches the reference exactly 3. Check label spelling and ensure it follows KUKA KRL naming conventions (case-sensitive) 4. If the label should be in another module, verify proper module qualification syntax is used in the reference 5. Verify all included files or dependencies are properly declared and accessible in the program structure 6. Recompile the program after making corrections to ensure the label is now properly declared in the local scope
