What causes KUKA Robot alarm KRC0753?

Array index variable contains a value larger than the array dimension. Loop counter increments beyond the array size without proper boundary checking. Incorrect array dimension declaration in the program structure. Signal index parameter passed from external source exceeds valid range. Mathematical calculation of index value produces an unexpectedly large number.

How do I fix KUKA Robot alarm KRC0753?

1. Review the KRL program code to identify which array or signal object is referenced at the point of alarm occurrence 2. Verify the declared dimension size of the array or signal object matches the intended usage 3. Check all index variables and loop counters to ensure they do not exceed the array bounds 4. Add boundary validation logic before array access operations to prevent index overflow 5. Review any external parameter inputs or calculations that determine index values 6. Test the program with debug mode enabled to monitor index variable values during execution

Alarm KRC0753

KUKA Robot KRC0753 - SIGNAL INDEX TOO LARGE 2089

This alarm indicates that an array or signal index value exceeds the maximum allowed bounds for the referenced object in the KRL program. The system detected an attempt to access an array element or signal using an index that is larger than the defined size of that object, causing an out-of-bounds condition.
