- Power Input (R, S, T): Connect the three-phase 380V AC power supply to the R, S, T terminals. Ensure correct phase sequence.
- Motor Output (U, V, W): Connect the three-phase AC motor to the U, V, W terminals.
- Grounding (PE): Connect the ground wire to the PE terminal. This is critical for safety.
- Control Terminals: Connect external control signals (e.g., start/stop, speed reference, fault reset) to the designated control terminals as per your application requirements. Refer to the detailed wiring diagram in the full product manual for specific terminal functions.
4.3 Initial Power-Up
After completing all wiring, double-check all connections for tightness and correctness. Apply power to the VFD. The digital display should illuminate. Do not connect the motor during the initial power-up if you intend to perform parameter settings without load.
5. Operating Instructions
5.1 Keypad Functions
The VFD features a user-friendly keypad for local control and parameter adjustment.

- RUN Button (Green): Initiates motor operation.
- STOP/RESET Button (Red): Stops motor operation and clears fault indications.
- Directional Arrows (Up/Down): Used to navigate menus and adjust parameter values.
- Rotary Knob: Used for fine-tuning frequency or selecting parameters.
- Digital Display: Shows operating status, frequency, current, voltage, and parameter values.
5.2 Basic Operation
- Start: Press the RUN button to start the motor. The motor will accelerate to the set frequency.
- Stop: Press the STOP/RESET button to stop the motor. The motor will decelerate and stop.
- Frequency Adjustment: Use the directional arrows or the rotary knob to adjust the output frequency, thereby controlling the motor speed.
5.3 Parameter Settings
The VFD has numerous parameters that can be configured to match specific motor and application requirements. Access the parameter menu using the keypad. Refer to the detailed parameter list in the comprehensive product manual for specific settings such as acceleration/deceleration times, motor parameters, and control modes.
6. Maintenance
Regular maintenance ensures the longevity and reliable operation of your VFD.
- Cleaning: Periodically clean the VFD's exterior and ventilation openings to prevent dust accumulation. Use a soft, dry cloth. Do not use liquid cleaners.
- Inspection: Regularly inspect the VFD for any signs of damage, loose connections, or discoloration. Check cooling fans for proper operation.
- Ventilation: Ensure that the VFD's cooling fins and fan are free from obstructions. Proper airflow is essential for heat dissipation and preventing overheating.
- Environmental Conditions: Verify that the operating environment remains within the specified temperature and humidity ranges.
