What causes KUKA Robot alarm KRC0386?

Incorrect file path syntax using backslashes instead of forward slashes in COPY source or target specification. Mismatched data types between source and target modules, such as attempting to copy a .src file to a .dat file location. Missing or invalid module extension (.src, .dat, .sub) in either the source or target specification. Using relative file paths without proper WorkVisual project context or absolute paths with non-existent directories. Network path specifications that do not conform to KUKA file transfer conventions or contain invalid characters.

How do I fix KUKA Robot alarm KRC0386?

1. Verify the file path syntax in the COPY command matches KUKA conventions, ensuring forward slashes and proper drive letter formatting 2. Confirm both source and target file extensions are valid and compatible (e.g., .src to .src, .dat to .dat) 3. Check that the source file exists and is accessible from the KRC4 controller using file browser in KUKA smartPAD 4. Review WorkVisual documentation for correct COPY command syntax and consult example programs within the KUKA system library 5. Test the COPY operation with absolute file paths in the KRC project root directory to eliminate path resolution ambiguity 6. Validate the command syntax by compiling the KRL module in offline mode using WorkVisual before uploading to the controller
