Common Causes

• Parameter _K was not initialized or was reset to 0 during cycle setup
• Incorrect cycle call syntax or missing _K parameter assignment before cycle execution
• Parameter _K value cleared by program error or manual parameter reset
• Cycle macro requires non-zero _K value for weighting factor calculation and was called with default/null value

Troubleshooting Steps

1. 1Verify the NC program block calling the cycle (CYCLE974, CYCLE977, CYCLE978, CYCLE979, CYCLE994, or CYCLE998) and confirm _K parameter is assigned a non-zero numeric value before cycle execution
2. 2Check cycle subroutine documentation for required _K weighting factor range and ensure assignment falls within valid specification
3. 3Review parameter list in the part program and machine configuration to confirm _K initialization; add explicit _K value assignment if missing
4. 4Reload the NC program or manually set _K parameter to appropriate weighting factor value (typically between 0.001 and 1.0 depending on cycle type) and restart block execution
5. 5If issue persists, verify machine parameter and cycle macro files are not corrupted by comparing against backup or manufacturer reference
