Common Causes

• Programmed parameter value exceeds the maximum or minimum limit defined by its data type (e.g., INTEGER, REAL, DWORD)
• Variable assignment receives a value outside the permissible range during program execution
• Incorrect scaling factor or multiplier applied to a constant in the part program
• Data type mismatch between source and destination variables in parameter assignment
• Overflow condition from arithmetic operations on variables with insufficient data type range

Troubleshooting Steps

1. 1Review the part program at the indicated block number and identify all constant and variable declarations, checking that values fall within their defined data type limits
2. 2Verify data type definitions in the program header or variable declarations—compare REAL, INT, DWORD, and other type ranges against the actual programmed values
3. 3Examine any arithmetic operations or calculations that produce the out-of-range value; confirm scaling factors and intermediate result ranges are appropriate for the data type
4. 4Check the CNC parameter settings and machine limits that may define upper/lower bounds for the affected variable or constant
5. 5Edit the part program to use appropriate data types with sufficient range, adjust constant values to be within limits, or split calculations to prevent overflow
