KUKA Robot KRC0468 - MEMORY REQUEST FOR PARAMETER LIST TOO LARGE

This alarm indicates that the parameter list required for program transfer exceeds the available memory allocation in the KRC controller. The system cannot allocate sufficient memory to store all transfer parameters needed for the current program execution, which prevents proper program initialization and execution.

KUKA Robot KRC0468 - MEMORY REQUEST FOR PARAMETER LIST TOO LARGE

MEMORY REQUEST FOR PARAMETER LIST TOO LARGE

This alarm indicates that the parameter list required for program transfer exceeds the available memory allocation in the KRC controller. The system cannot allocate sufficient memory to store all transfer parameters needed for the current program execution, which prevents proper program initialization and execution.

Common Causes

  • Program contains excessively large or numerous local variables and parameters
  • Transfer parameter data structure exceeds controller memory capacity limits
  • Multiple programs loaded simultaneously consuming available RAM
  • Insufficient memory remaining due to other running processes or cached data
  • Parameter list includes large array declarations or complex data structures without optimization

Troubleshooting Steps

  1. 1Review and reduce the number of local variables and parameters in the program, consolidating where possible
  2. 2Break the program into smaller subroutines to distribute parameter memory usage across multiple calls
  3. 3Clear controller memory cache and restart the KRC system to free available RAM
  4. 4Unload unused programs or background tasks consuming memory resources
  5. 5Optimize data structures by using efficient variable types and removing unnecessary array declarations
  6. 6Contact KUKA support if memory requirements are legitimate and consider controller upgrade or additional memory modules
