Alarm KRC1005

KUKA Robot KRC1005 - INT. CONSTANT NOT EQUAL 0 EXPECTED 2342

This alarm indicates that an internal constant in the KRL program has an unexpected value at runtime. The system expected a constant to equal 2342, but it was found to have a different value (not equal to 0), suggesting data corruption or an incorrect constant definition in the program object.

KUKA Robot KRC1005 - INT. CONSTANT NOT EQUAL 0 EXPECTED 2342

INT. CONSTANT NOT EQUAL 0 EXPECTED 2342

This alarm indicates that an internal constant in the KRL program has an unexpected value at runtime. The system expected a constant to equal 2342, but it was found to have a different value (not equal to 0), suggesting data corruption or an incorrect constant definition in the program object.

Common Causes

  • Corrupted or modified constant definition in the KRL source code
  • Incorrect initialization value assigned to the internal constant during compilation
  • Memory corruption affecting the constant storage area
  • Mismatched KRL program version or incompatible module compilation
  • Invalid constant redefinition or shadowing by a global variable with the same name

Troubleshooting Steps

  1. 1Review the KRL program source code and verify all internal constant definitions match expected values
  2. 2Recompile the affected KRL module to regenerate the constant definitions
  3. 3Check the program's .src and .src.bak files for any unexpected changes or corruption
  4. 4Clear the robot controller cache and reload the program from source
  5. 5If using multiple program versions, verify the correct version is loaded on the controller
  6. 6Contact KUKA support with the program object details and a backup of the affected source files if the issue persists
