| Fault Code | Description | Common Cause | Immediate Action | | :--- | :--- | :--- | :--- | | | Output Overcurrent (Instantaneous) | Short circuit in motor cables; defective motor winding. | Disconnect power. Megger test motor insulation. | | F102 | Ground Fault | Phase-to-ground short inside motor or cable. | Check all cable glands and terminals for moisture or chafing. | | F103 | Overload (I²t) | Mechanical jam; extended stall condition. | Manually rotate driven load. Check gearbox bearings. | | F110 | Dynamic Braking Overload | Regenerative power exceeds braking resistor capacity. | Increase deceleration time; check resistor for open circuit. | | F112 | Short Circuit on Output Phase U | Power transistor (IGBT) failure in U-leg. | Replace PPCR221 power module. Do not reset without repair. |
