Alarm KRC0457

KUKA Robot KRC0457 - INTERRUPTUP: MAX. 10 ARGUMENTS ADMISSIBLE

This alarm indicates that an INTERRUPT function call in the KRC program has been invoked with more than the maximum allowable number of arguments. The KUKA KRC controller strictly limits INTERRUPT declarations to a maximum of 10 parameters, and this threshold has been exceeded in the current program logic.

KUKA Robot KRC0457 - INTERRUPTUP: MAX. 10 ARGUMENTS ADMISSIBLE

INTERRUPTUP: MAX. 10 ARGUMENTS ADMISSIBLE

This alarm indicates that an INTERRUPT function call in the KRC program has been invoked with more than the maximum allowable number of arguments. The KUKA KRC controller strictly limits INTERRUPT declarations to a maximum of 10 parameters, and this threshold has been exceeded in the current program logic.

Common Causes

  • INTERRUPT function declared with more than 10 formal parameters in the program source code
  • Incorrect nesting or stacking of multiple INTERRUPT calls with cumulative parameters
  • Copy-paste error when creating INTERRUPT declarations that duplicated parameter lists
  • Legacy code migration from another controller platform with different parameter limits
  • Misunderstanding of INTERRUPT syntax where data structures should be used instead of individual parameters

Troubleshooting Steps

  1. 1Review the INTERRUPT function declaration in the KRC source code and count the actual number of parameters specified
  2. 2Reduce the number of arguments to 10 or fewer by consolidating related parameters into structured data types (REAL arrays or custom data structures)
  3. 3Use global variables or local variable arrays to pass additional data to the INTERRUPT handler instead of function parameters
  4. 4Verify the correct INTERRUPT syntax in the KUKA KRC programming documentation for your controller version
  5. 5Test the modified program with the reduced parameter set and monitor the alarm logs to confirm resolution
  6. 6If structural changes are required, document the modification and perform regression testing on affected motion sequences
