KRC0482

KUKA Robot KRC0482 - Line selection beyond buffer: Next start deletes buffer.

Line selection beyond buffer: Next start deletes buffer.

This alarm occurs when a line selection command references a program line that exceeds the available buffer memory or trace boundaries in the KUKA KRC controller. The next program start execution will overwrite and delete the current buffer contents, potentially causing loss of stored program data or trace information.

Common Causes

  • Program line number selection exceeds the maximum buffer capacity of the controller
  • Attempting to jump to a line number beyond the currently loaded program range
  • Corrupted or incomplete program file loaded into controller memory
  • Buffer overflow caused by excessive program data or trace logging
  • Attempting to access a line in an external program file that is not properly referenced or linked

Troubleshooting Steps

  1. 1Verify the target line number in the program does not exceed the total number of lines in the loaded program
  2. 2Check the program buffer size settings in the controller configuration and ensure sufficient memory allocation
  3. 3Reload the complete program file to the controller to ensure all lines are properly indexed and buffered
  4. 4Review the program trace or debug log to identify which line selection command triggered the alarm
  5. 5Clear the controller buffer and cache by performing a controlled restart or memory reset operation
  6. 6Contact KUKA support with the program file and detailed reproduction steps if the issue persists after verification
