KRC0740

Common Causes

• A numeric variable or parameter is assigned a value below the minimum required limit
• Incorrect initialization of loop counters, array indices, or dimensioning parameters
• A calculation result produces a value that falls below the acceptable range for the operation
• Configuration parameter or system setting is set to a value outside the valid minimum boundary
• Runtime value from sensor input or external source is below the minimum threshold required

Troubleshooting Steps

1. 1Review the KRL program code at the line where alarm KRC0740 is triggered and identify the numeric variable or parameter involved
2. 2Check the technical documentation for the specific function or object to determine the minimum allowable value requirement
3. 3Verify all variable initializations and ensure they meet the minimum value constraints before program execution
4. 4Add validation logic or conditional checks in the program to ensure values remain within acceptable ranges before operations
5. 5Test the program with known valid input values that exceed the minimum threshold to confirm proper operation
6. 6If using external input or sensor data, verify the data source is functioning correctly and providing values within the required range
