4. Installation and Wiring
Proper installation and wiring are critical for the safe and effective operation of the VFD. Refer to the following instructions and the provided video for a visual guide.
4.1. Wiring Connections
The VFD features clearly labeled terminal blocks for input power, motor output, and control signals. Ensure all connections are secure and correctly polarized.
Figure 4.1: Detailed view of the VFD's wiring terminals.
- Input Power (Single-Phase): Connect the single-phase 220V AC power supply to any two of the R, S, T input terminals.
- Motor Output (Three-Phase): Connect the three-phase motor to the U, V, W output terminals.
- Grounding: Connect the ground wire to the FG terminal.
- Control Wiring (Optional): For external control devices (e.g., RS485 communication, potentiometer, switches), connect RS485+ and RS485- for communication. If the control device requires power, connect GND and 24V.

The control panel includes buttons for 'PROG' (Program), 'FUNC/DATA' (Function/Data), 'UP/DOWN' arrows, 'OK', 'RUN', and 'STOP/RESET'. The rotary knob is used for frequency adjustment.
5.2. Parameter Setting
To ensure optimal performance, set the VFD parameters according to your motor's nameplate specifications. The following example demonstrates setting parameters for a 380V motor. Adjust values as per your motor's requirements.
- Press the 'PROG' button to enter the parameter setting mode. The display will show 'F0.00'.
- Use the 'UP/DOWN' arrows to navigate to the desired parameter group (e.g., F1-xx for motor parameters).
- Press 'ENTER' to select the parameter group.
- Use 'UP/DOWN' arrows and 'SHIFT' to adjust the parameter value.
- Press 'ENTER' to save the new value.
- Press 'PROG' to exit the parameter setting mode.
Example Motor Parameter Settings (Refer to Video 4.1 for demonstration):
- F1-01 (Power): Set to 2.2 (for a 2.2 KW motor).
- F1-02 (Voltage): Set to 380 (for a 380V motor).
- F1-03 (Amperage): Set to 7 (for a 7A motor).
- F1-04 (Frequency): Set to 60 (for a 60 Hz motor).
- F1-05 (RPM): Set to 3450 (for a 3450 RPM motor).
5.3. Starting and Stopping
- Press the 'RUN' button to start the motor.
- Press the 'STOP/RESET' button to stop the motor.
- Adjust the frequency using the rotary knob during operation to control motor speed.
