KUKA Robot KRC0810 - “ENDWHILE” MISSING 2146
“ENDWHILE” MISSING 2146
This alarm indicates a syntax error in the KRL program where an ENDWHILE statement is missing or improperly placed. The parser encountered the end of a WHILE loop structure without finding the required ENDWHILE keyword to properly close the loop block.
Common Causes
- Missing ENDWHILE statement at the end of a WHILE loop block
- Incorrect nesting of WHILE loops with mismatched ENDWHILE statements
- Typo in ENDWHILE keyword (e.g., 'END WHILE', 'ENDWH', 'ENDWHILE;')
- ENDWHILE placed at wrong indentation level or in wrong scope
- Missing or extra braces/keywords disrupting loop structure syntax
Troubleshooting Steps
- 1Open the KRL program file and locate the line number referenced in the error message
- 2Review all WHILE loops in the program and verify each has a corresponding ENDWHILE statement
- 3Check for proper spelling and syntax of ENDWHILE - ensure no extra spaces or characters
- 4Verify correct nesting of loops by matching each WHILE with its corresponding ENDWHILE at the proper indentation level
- 5Use the KRL editor's bracket/brace matching feature to identify unmatched loop structures
- 6Correct the syntax error by adding the missing ENDWHILE statement or fixing the existing one, then recompile and test the program
