| Fault Code | Name (as per manual) | Common Solution | | :--- | :--- | :--- | | | Overcurrent | Check for short circuits, excessive load, or aggressive acceleration (C1-01). | | OV | Overvoltage | Deceleration too fast (C1-02) or regenerative energy from fan windmilling. | | PF | Input Phase Loss | Loose wire on L1/L2/L3; blown input fuse. | | LF | Output Phase Loss | Broken wire between drive and motor. | | bUS | Option Card Communication Error | Loose connector on the RS485/Modbus card. | | CPF06 | EEPROM Error | Parameter corruption. Try initializing with A1-03 (Initialize). |

Note: Autotuning is required for Vector Control modes to ensure proper performance. | Fault Code | Name (as per manual)
If you need high performance, use the Auto-Tuning function (usually under the T1 parameter group) to let the drive measure your motor's characteristics automatically. 4. Troubleshooting Faults | | LF | Output Phase Loss |
Manuals dictate proper mounting (often vertical for heat dissipation) and electrical grounding to prevent interference and equipment failure. Operational and Parameter Setup
