KUKA Robot KRC0669 - “DEFDAT” EXPECTED 2005

“DEFDAT” EXPECTED 2005

This alarm indicates that a DEFDAT (default data) structure or declaration in the KRL program was expected to conform to the 2005 KUKA software version specification but does not match. The system detected incompatible data format, missing fields, or incorrect structure definition in <object name> that prevents proper initialization or execution.

Common Causes

  • DEFDAT structure definition uses outdated or non-2005 compatible syntax
  • Missing or incorrectly named required fields in the DEFDAT declaration
  • Data type mismatch between the expected 2005 specification and actual definition in <object name>
  • KRL program was created or modified in a different KUKA software version and not properly converted
  • Corrupted or incomplete DEFDAT initialization data in the program file

Troubleshooting Steps

  1. 1Verify the KUKA software version matches 2005 specification requirements for the project
  2. 2Locate <object name> in the KRL source code and review the DEFDAT structure declaration for syntax errors
  3. 3Compare the DEFDAT definition against official 2005 KUKA documentation to ensure all required fields are present and correctly typed
  4. 4Re-declare the DEFDAT structure using the correct 2005 format, ensuring proper field names, data types, and initialization values
  5. 5If the program originated from a different software version, use KUKA's program conversion tools or manually update the structure to match 2005 specifications
  6. 6Recompile the KRL program and download it to the robot controller to verify the alarm is resolved
