Alarm KRC0175

KUKA Robot KRC0175 - NO MORE USER MEMORY AVAILABLE

This alarm indicates that the KRC controller's user memory has been exhausted and cannot allocate additional space for copying objects, such as programs, data structures, or workspace elements. The system cannot complete the requested copy operation because insufficient contiguous or total memory is available in the user memory partition. This typically occurs when working with large programs, extensive teach points, or complex data structures.

NO MORE USER MEMORY AVAILABLE

This alarm indicates that the KRC controller's user memory has been exhausted and cannot allocate additional space for copying objects, such as programs, data structures, or workspace elements. The system cannot complete the requested copy operation because insufficient contiguous or total memory is available in the user memory partition. This typically occurs when working with large programs, extensive teach points, or complex data structures.

Common Causes

  • User memory is completely full due to accumulated programs and data files
  • Attempting to copy very large program files or workspace configurations that exceed available free memory
  • Memory fragmentation from repeated creation and deletion of programs without defragmentation
  • Multiple large teach point sets or complex data structures consuming excessive memory
  • System cache or temporary files not being properly cleared after program edits

Troubleshooting Steps

  1. 1Check available user memory in the KRC controller via the System menu and verify total free space
  2. 2Delete unnecessary or obsolete program files and data structures to free up memory space
  3. 3Perform a memory defragmentation routine through the controller's maintenance utility if available
  4. 4Split large program files into smaller modular components and store them separately
  5. 5Clear the system cache and temporary workspace data by restarting the controller or using maintenance functions
  6. 6Verify that the copy operation parameters are correct and consider breaking the copy into smaller segments if possible
