What causes KUKA Robot alarm KRC0890?

Missing or invalid numeric value in array declaration or initialization. Incorrect syntax in AXIS or FRAME declaration with missing positive integer. Invalid parameter passed to a function expecting a positive integer constant. Using a variable or expression instead of a literal positive integer where constant is required. Typo or formatting error in numeric constant definition.

How do I fix KUKA Robot alarm KRC0890?

1. Review the KRL source code at the line number indicated in the error message 2. Verify all array declarations have proper positive integer dimensions (e.g., INT array[10]) 3. Check that all function calls use literal positive integers for constant parameters 4. Ensure numeric literals are properly formatted without leading zeros or invalid characters 5. Compare the code syntax against KUKA KRL programming documentation for correct constant declaration 6.
