| UV | DC bus undervoltage | Check grid voltage, shorten acceleration time, check input phase loss. |
| OC | Output overcurrent | Check insulation of motor and cables, reduce load, extend acceleration time. |
| OH | Frequency converter overtemperature | Check cooling fan, clean air duct, reduce ambient temperature. |
| PH | Input phase loss | Check input power supply, tighten wiring terminals, replace damaged fuses. |
| GF | Ground fault | Check insulation of motor and cables, eliminate ground fault points. |
VII. Installation and Wiring Key Points
- Antes da instalação, confirm that the power supply voltage matches the rated voltage of the frequency converter, disconnect the power supply and verify no voltage.
- Adopt 35mm DIN rail mounting or wall-mounted mounting to ensure sufficient heat dissipation space.
- Main circuit wiring: R/L1, S/L2, T/L3 are inputs; Você, V, W are outputs; PE is the grounding terminal.
- Control circuit wiring: Shielded wires should be used for analog input, with the shielding layer grounded at one end; digital input should avoid routing in the same slot as high-voltage electricity.
- Check parameter settings before power-on, especially basic parameters such as motor rated power, rated current and rated frequency.
