Common Causes

• Tool length offset (TLO) not properly defined or initialized before cycle execution
• Workpiece coordinate system (WCS) or machine zero reference not established
• F_SP_RP cycle called without proper tool engagement in retraction area
• Conflicting geometry definitions in part program causing ambiguous retraction path
• Previous cycle or manual operation left tool in undefined spatial relationship to workpiece

Troubleshooting Steps

1. 1Verify tool length offset values are loaded and match the physical tool setup; reload TLO table if necessary
2. 2Confirm machine reference point (machine zero) has been executed and active coordinate system is valid
3. 3Review part program block sequence leading to F_SP_RP cycle; ensure tool position and geometry are unambiguous before cycle call
4. 4Check workpiece coordinate system definition and verify WCS offset matches actual workpiece setup on machine
5. 5Execute manual retraction move in safe direction using manual jog controls, then reset alarm and re-attempt cycle with corrected geometry data
