KRC0746

Common Causes

• Passing a variable of wrong data type (e.g., REAL instead of POS) to a function expecting POS, FRAME, or AXIS
• Missing or incomplete position/frame declaration in a function call or instruction parameter
• Using uninitialized variables in position or frame assignments
• Incorrect syntax when defining or referencing axis-specific parameters
• Attempting to use a non-position variable (such as INT or CHAR) where a POS, FRAME, or AXIS type is required

Troubleshooting Steps

1. 1Review the KRL source code line referenced in the alarm message to identify the problematic function call or instruction
2. 2Verify that all function parameters match their expected data types (POS, FRAME, or AXIS) in the function definition
3. 3Check variable declarations to ensure POS, FRAME, and AXIS variables are properly initialized before use
4. 4Confirm correct syntax for position and frame definitions (e.g., {X 100, Y 200, Z 300, A 0, B 0, C 0})
5. 5Validate that all arguments passed to movement commands (e.g., PTP, LIN) use the correct data types
6. 6Compile the program to generate detailed error messages showing the exact parameter at fault, then correct the data type or variable reference
