What causes KUKA Robot alarm KRC0975?

Declared parameter type is not a valid KRL data type (e.g., misspelled INT, REAL, BOOL, etc.). Using unsupported or deprecated data types in function/module definitions. Incorrect syntax when defining array or structure parameters. Mixing incompatible type declarations with AXIS or FRAME parameters. Parameter declared with reserved keywords or system-protected type names.

How do I fix KUKA Robot alarm KRC0975?

1. Review the function/module definition in the source file and identify parameter @P1@ 2. Verify the parameter type is a valid KRL primitive type (INT, REAL, BOOL, CHAR, etc.) or supported complex type 3. Check KRL language documentation for correct parameter declaration syntax 4. Correct any misspelled type names and ensure proper spacing and formatting 5. If using custom types or structures, confirm they are properly defined before use 6. Recompile the program and verify the alarm is resolved; if persists, contact KUKA support with the specific parameter declaration
