| Fault Code | Description | Probable Cause | Corrective Action | | :--- | :--- | :--- | :--- | | | Following Error Exceeded | Motor cannot keep up with commanded position. Load jammed or tuning too aggressive. | 1. Check mechanical drive train for jams. 2. Reduce acceleration/speed. 3. Retune servo loop gains (Kv, Tn). | | F4100 | Position Limit Switch Tripped | Axis moved beyond soft or hard limits. | 1. Manually jog axis back into range. 2. Check limit switch wiring (if hard switch). | | F4200 | Drive Enable Missing | Hardware enable signal removed unexpectedly. | 1. Check safety circuit (E-Stop, Light curtains). 2. Check 24VDC supply to enable inputs. | | F5001 | PLC Program Error | Runtime error in the user logic (e.g., division by zero). | 1. Check PLC logs for specific line number. 2. Debug logic code. |
