KUKA Robot KRC1028 - <object name> NOT ENOUGH MEMORY, FILE OPEN ERROR 2713

<object name> NOT ENOUGH MEMORY, FILE OPEN ERROR 2713

This alarm indicates that the KRL program object (module, function, or variable) named @P1@ cannot be opened due to insufficient memory allocation or a file system error. The controller's memory resources are exhausted or the file is corrupted, preventing proper loading of the specified KRL object.

Common Causes

  • Insufficient RAM available on the KRC controller for the program object size
  • Corrupted KRL source or compiled file preventing proper file reading
  • Too many programs or objects loaded simultaneously consuming available memory
  • File system errors or bad sectors on the controller's storage device
  • KRL object exceeds maximum allowable size limits for the controller model

Troubleshooting Steps

  1. 1Check available memory on the KRC controller via diagnostics menu and note current RAM usage
  2. 2Close or unload unnecessary KRL programs and objects to free up memory resources
  3. 3Verify the KRL source file (@P1@) is not corrupted by recompiling or replacing from backup
  4. 4Clear the controller's temporary memory cache by performing a soft reset if safe to do so
  5. 5Reduce the size of the problematic KRL object by splitting it into smaller modules or removing unnecessary declarations
  6. 6If issue persists, backup all programs and perform a complete system reset or contact KUKA service for memory diagnostics
