KUKA Robot KRC0937 - ARRAY INVALID 1 2274
ARRAY INVALID 1 2274
This alarm indicates an invalid array operation or access in the KRL program at the specified object. The system detected an attempt to access an array element that violates the array's defined bounds, structure, or initialization state.
Common Causes
- Array index out of bounds - attempting to access an element beyond the declared array size
- Array not properly initialized before use - accessing an uninitialized or null array
- Incorrect array dimension specification - mismatch between declared and accessed dimensions
- Type mismatch in array element assignment or comparison
- Dynamic array size exceeded or memory allocation failure
Troubleshooting Steps
- 1Review the KRL source code at the specified object name to identify the array operation causing the error
- 2Verify array declarations match their usage - check array dimensions, data types, and initialization
- 3Validate all array index calculations to ensure they remain within bounds (0 to size-1)
- 4Confirm arrays are properly initialized before any read or write operations
- 5Add bounds checking and error handling logic around array operations using conditional statements
- 6Recompile the KRL program and test with valid input data to confirm the fix
