4.1 Terminal Block Overview
Figure 4.1: VFD Terminal Block.
The VFD features clearly labeled terminals for input power, motor output, and control signals. Refer to the detailed wiring diagram for specific connections.
4.2 Power Input Wiring (220V AC)
The Huanyang VFD supports both single-phase and three-phase 220V AC input.
Single-Phase Input:
Connect the single-phase 220V AC input to the 'R' and 'S' terminals of the VFD. The 'T' terminal remains unused for single-phase input.
Figure 4.2: Single-Phase Input Wiring to VFD.
Three-Phase Input:
Connect the three-phase 220V AC input to the 'R', 'S', and 'T' terminals of the VFD.
Figure 4.3: Three-Phase Input Wiring to VFD.
4.3 Motor Output Wiring
Connect the three-phase motor to the 'U', 'V', and 'W' output terminals of the VFD. Ensure correct phase rotation for your application. If the motor rotates in the wrong direction, swap any two of the U, V, W wires.
4.4 Control Wiring (Optional)
The VFD supports external control options such as remote potentiometers for speed control and external switches for start/stop functions, as well as RS-485 communication.
Figure 4.4: Basic Connection Diagram with Control Options.
For detailed control wiring, refer to the specific parameters (e.g., PD001, PD002, PD070) in the programming section.
5. Operating Instructions
After completing the wiring and ensuring all safety precautions are met, you can power on the VFD and begin operation.
5.1 Initial Power-On and Basic Operation
- Power On: Apply power to the VFD. The digital display should illuminate.
- Start Motor: Press the RUN button on the control panel. The motor should start and accelerate to the set frequency.
- Adjust Speed: Rotate the speed controller knob on the control panel to adjust the motor's operating frequency (speed).
- Stop Motor: Press the STOP/RESET button to stop the motor.
- Reverse Direction: Press the REV button to change the motor's rotation direction while running or before starting.
5.2 Parameter Programming
The VFD's behavior can be customized through various parameters. The unit is factory-set to 400Hz. If your motor is rated at 400Hz, direct connection is possible. Otherwise, adjust parameters according to your motor's specifications.
General Programming Steps:
- Press the PRGM button to enter programming mode.
- Use the UP or DOWN arrow keys to navigate to the desired parameter (e.g., PD001).
- Press the SET button to select the parameter for editing.
- Use the UP or DOWN arrow keys to change the parameter value. Use the SHIFT button to move the cursor for digit selection.
- Press the SET button to save the new value.
- Press PRGM again to exit programming mode.
