What causes KUKA Robot alarm KRC1029?

Excessive array or data structure allocation without proper deallocation. Memory leak caused by repeated object creation in loops without cleanup. Large data buffers or strings being created and retained in memory. Insufficient system RAM allocated to the KRC controller for program execution. Multiple concurrent programs consuming memory without proper resource management.

How do I fix KUKA Robot alarm KRC1029?

1. Review the KRL source code of the named object to identify large data structure allocations and optimize memory usage 2. Check for memory leaks by examining loops that create objects and ensure proper cleanup/deallocation 3. Reduce the size of arrays, buffers, or data structures where feasible without compromising functionality 4. Verify the robot controller has sufficient available system memory by checking system diagnostics 5. Split large programs into smaller modules and use local scope variables to minimize memory footprint 6. Restart the KRC controller to clear memory caches and reset the runtime environment if no code changes are immediately available

Alarm KRC1029

KUKA Robot KRC1029 - <object name> NO FREE PHYSICAL MEMORY 2714

This alarm indicates that the KRL program object (module, function, or variable) specified in the message has exhausted available physical memory during runtime execution. The system cannot allocate additional memory needed to continue program execution, resulting in a critical memory allocation failure.
