What causes KUKA Robot alarm KRC0786?

Array index out of bounds or incorrect array dimensions specified during declaration. Structure or user-defined type instantiated with wrong number of elements or fields. Parameter passed to a function has incompatible dimensions compared to the function signature. Type casting or conversion attempted between incompatible data types with different dimensional properties. Global or local variable redeclared with different dimensions than originally defined.

How do I fix KUKA Robot alarm KRC0786?

1. Review the KRL source code and verify the object declaration matches all usage instances throughout the program 2. Check function signatures and ensure all function calls pass parameters with correct dimensional specifications 3. Inspect array and structure definitions to confirm indices and element counts are consistent with declarations 4. Compare the object definition in the header file or module against where it is being used in the main program 5. Clear all compiled program files and recompile the entire KRL project to eliminate cached dimension references 6. If error persists, export the program, create a minimal test case isolating the problematic object, and verify the declaration syntax is correct

KUKA Robot KRC0786 - INCORRECT DIMENSION 2122

This alarm indicates that a KRL program object has been declared or used with incorrect dimensional specifications. The dimension mismatch typically occurs when an array, structure, or complex data type is referenced with parameters that don't match its original declaration.
