KUKA Robot KRC0502 - Selection not possible
Selection not possible
The KRC0502 alarm indicates that file selection in the KRL editor has failed, typically due to the target file being unavailable, deleted, or marked with hidden file attributes in the WorkVisual environment. This prevents the editor from opening or accessing the specified program file for editing or execution.
Common Causes
- File does not exist in the specified directory path
- File has hidden attribute enabled in Windows file system properties
- File permissions restrict access from the KUKA controller
- Network path disconnected when accessing remote file locations
- File was deleted after initial program selection but before editor launch
Troubleshooting Steps
- 1Verify the file exists by navigating to the project directory using WorkVisual file browser
- 2Check file properties and disable hidden attribute if present in Windows Explorer
- 3Confirm read and execute permissions are granted for the controller user account
- 4Verify network connectivity if using remote file paths on mapped drives
- 5Reload the project in WorkVisual and attempt selection again
- 6Restore the file from backup if it was accidentally deleted or corrupted
