What causes KUKA Robot alarm KRC0828?

FOR or WHILE loop with insufficient or missing exit conditions. Counter variable not being properly incremented or reset between iterations. Infinite loop or recursion depth exceeding system limits in @P1@. Array indexing or list traversal without proper boundary checking. Logic error in loop condition causing more iterations than intended.

How do I fix KUKA Robot alarm KRC0828?

1. Review the KRL source code in object @P1@ and locate all loop structures (FOR, WHILE) 2. Verify that loop exit conditions are logically correct and will eventually become true 3. Check that counter variables are properly initialized before use and incremented/decremented correctly 4. Add explicit loop iteration limits or breakpoint conditions to prevent excessive iterations 5. Test the program logic offline using KRC simulation mode with debug breakpoints to trace execution flow 6. If recursion is involved, check the recursion depth and add base case conditions to prevent stack overflow

Alarm KRC0828

KUKA Robot KRC0828 - COUNT EXCEEDED 2164

This alarm indicates that a counter or loop iteration has exceeded its maximum allowed value of 2164 in the KRL program object @P1@. This typically occurs when a FOR loop, WHILE loop, or internal counter operation surpasses the system's predefined threshold, causing the program execution to halt as a safety measure.
