| Fault Code | Description | Likely Cause | Solution from Manual | | :--- | :--- | :--- | :--- | | | Overcurrent | Short circuit, ramp too fast, motor too small. | Increase P01/P02. Check motor windings. | | OU | Overvoltage | Regenerative braking. | Increase decel time (P02). Add braking resistor. | | LU | Undervoltage | Input voltage drop. | Check mains supply. Check L1/L2 connections. | | OL | Overload (Motor) | Motor exceeds rated current >60s. | Reduce load. Increase P05 (within motor limits). | | OH | Overtemperature | Fan blocked or ambient too hot. | Clean heatsink. Improve ventilation. | | SC | Short Circuit | Dead short at T1/T2/T3. | Check motor cable. Replace drive if persistent. | | CE | Communication Error | RS485 issue. | Check wiring. Verify protocol settings. |
