INTERNAL ERROR WHEN ACCESSING <object name>

An internal system error occurred while the KRC4 controller attempted to access or manipulate a specified file or object, preventing the requested operation from completing successfully. This error typically indicates a file system issue, permission problem, or corrupted data structure within the robot control system.

Common Causes

  • Corrupted file system on the KRC4 compact flash card or solid state storage device
  • Insufficient storage space available on the robot controller memory
  • File permissions or access rights are incorrectly configured in the KRC system
  • Interrupted file write operation due to power loss or emergency stop during program save or update
  • Defective storage hardware such as failing compact flash card or faulty storage interface

Troubleshooting Steps

  1. 1Note the specific object name mentioned in the alarm message and document the current system state
  2. 2Perform a basic system reboot by cycling the KRC4 controller power off and on to clear transient errors
  3. 3Verify available free storage space using the file manager in the KRC4 system and delete unnecessary files if needed
  4. 4Attempt to reload the affected program or configuration file from a known good backup copy
  5. 5Use WorkVisual to perform a system diagnosis and check the file system integrity for logical errors
  6. 6If the error persists, contact KUKA service for advanced diagnostics or storage device replacement
