What causes KUKA Robot alarm KRC0453?

BREAK statement placed inside a loop without proper conditional logic to exit. Recursive function calls resulting in repeated BREAK execution. Incorrect program logic causing continuous re-entry into BREAK statement. BREAK statement used outside of a valid loop or switch structure context. Program structure error where BREAK is not properly nested within control flow statements.

How do I fix KUKA Robot alarm KRC0453?

1. Review the program source code and locate all BREAK statements to verify they are within valid loop or switch structures 2. Check the conditional logic preceding each BREAK statement to ensure loops can properly exit before BREAK is executed 3. Verify that BREAK statements are not being called recursively or repeatedly without proper exit conditions 4. Validate program syntax using the KRC IDE compiler to identify structural errors in control flow 5. Test the program in manual mode or with reduced velocity to observe execution flow and identify where repeated BREAK statements occur 6. Restructure the program logic to ensure proper loop termination conditions and remove any unintended BREAK command repetitions

Alarm KRC0453

KUKA Robot KRC0453 - ABORTED

The KRC0453 alarm indicates that a BREAK statement in the robot program has been executed repeatedly or continuously, causing the program execution to be aborted. This typically occurs when a BREAK command is placed in a loop without proper conditional logic to exit the loop, or when the BREAK statement is being called in an unintended manner that prevents normal program flow.
