KRC0522

Common Causes

• Uninitialized or zero-valued variable used as divisor in arithmetic expression
• Sensor input or feedback value is zero when expected to be non-zero
• Incorrect conditional logic allowing division by a calculated value that evaluates to zero
• Parameter or offset value not properly initialized before use in division operation
• Tool offset, payload, or kinematic parameter contains zero value in denominator calculation

Troubleshooting Steps

1. 1Review the KRL program source code and identify the line number where the division operation occurs
2. 2Add conditional logic (IF statements) to validate that the divisor is non-zero before performing the division
3. 3Verify all variables and parameters used as divisors are properly initialized with non-zero values at program start
4. 4Check sensor inputs and feedback values that feed into divisor calculations for validity and expected ranges
5. 5Implement error handling using conditional branches or exception handling to safely handle cases where division by zero might occur
6. 6Clear the alarm, correct the program logic, and perform a full program validation and test run in manual mode before resuming automatic operation
