1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of the Huanyang HY Series Variable Frequency Drive (VFD). This VFD is specifically designed to convert single-phase 110/120V AC power into three-phase 110V AC power, enabling the efficient operation of three-phase motors and spindles from a single-phase electrical supply. The 3kW (4HP) model is covered in this document.
For comprehensive information, please refer to the official Installation Manual (PDF).
2. Safety Information
WARNING: Electrical shock hazard. Improper installation or operation can result in serious injury or death.
- Ensure all power is disconnected before installation, wiring, or maintenance.
- Installation and wiring should only be performed by qualified personnel.
- Proper grounding is essential for safe operation.
- Do not touch internal components immediately after power-off, as residual voltage may be present.
- The VFD output terminals are for three-phase motors only and should not be connected to other devices or used as a three-phase power source.

4. Setup and Installation
4.1. Wiring Diagram
Careful attention to wiring is critical for the safe and correct operation of the VFD. Always ensure power is disconnected before making any connections.
Figure 4.1.1: Basic connection diagram for the Huanyang VFD, showing input (R, S, T, E), output (U, V, W to three-phase electric appliance), control terminals (Potentiometer Control, Multi-input, Rs485), and optional Braking Resistor connection. Note: The diagram is for reference; refer to the actual product and detailed manual for precise wiring.
4.2. Connection Examples
Below are examples of how to connect the VFD to different types of three-phase motors.
Figure 4.2.1: Example wiring for connecting the VFD to a 400Hz spindle motor. The 110V AC input is connected to R and T, and the U, V, W outputs are connected to the spindle motor.
Figure 4.2.2: Example wiring for connecting the VFD to a standard three-phase asynchronous motor. The 110V AC input is connected to R and T, and the U, V, W outputs are connected to the motor.

5. Operation
5.1. Control Panel Functions
The VFD features a control panel for direct operation and parameter adjustment.
Figure 5.1.1: Labeled control panel showing the 5-digit display, Run key, Stop/Reset key, FOR/REV Switch, Shift key, Speed controller (rotary knob), Function key, Set key (Enter), Ascending key, and Descending key.
- RUN Key: Initiates motor operation.
- STOP/RESET Key: Stops motor operation or clears error codes.
- FOR/REV Switch: Changes the direction of motor rotation (Forward/Reverse).
- Shift Key (>>>): Moves the cursor or shifts digits during parameter setting.
- Speed Controller (Knob): Adjusts the output frequency/motor speed.
- PRGM Key (Function Key): Enters or exits the parameter programming mode.
- SET Key (Enter): Confirms parameter settings.
- Up/Down Keys (▲/▼): Adjusts parameter values.
5.2. Basic Operation Steps
- Ensure all wiring is correct and secure.
- Apply single-phase 110/120V AC power to the VFD input terminals (R, T).
- Use the PRGM key to access parameter settings if initial configuration is required. Refer to the manual for specific parameter codes (e.g., PD001 for source of run command, PD003 for main frequency, PD005 for maximum frequency).
- Press the RUN key to start the motor.
- Adjust the motor speed using the Speed Controller knob or the Up/Down keys.
- Press the STOP/RESET key to halt motor operation.
6. Maintenance
Regular maintenance ensures the longevity and reliable operation of your VFD.
- Cleaning: Periodically clean the VFD's exterior to prevent dust accumulation, especially around ventilation openings. Use a soft, dry cloth. Do not use liquid cleaners.
- Ventilation: Ensure adequate airflow around the VFD. The internal cooling fan operates continuously when the unit is powered on to maintain optimal operating temperatures. Do not obstruct air vents.
- Connections: Regularly check all wiring connections for tightness and signs of wear or corrosion.
- Environment: Operate the VFD within its specified environmental conditions (temperature, humidity, dust level) to prevent damage.
7. Troubleshooting
If you encounter issues with your VFD, consider the following common troubleshooting steps:
- No Power: Check the input power supply and all power connections. Ensure the VFD is properly connected to a single-phase 110/120V AC source.
- Motor Not Running: Verify that the RUN command is active. Check motor wiring (U, V, W) and ensure it is a three-phase motor. Confirm that VFD parameters are correctly set for your motor.
- Error Codes: If an error code appears on the display, consult the detailed PDF manual for the specific meaning of the code and recommended corrective actions.
- Incorrect Speed: Check the speed control input (potentiometer or digital setting) and relevant frequency parameters.
- Overload/Overcurrent: Ensure the motor's power rating does not exceed the VFD's capacity. Check for mechanical issues with the motor or load.
If you encounter an error code or are unable to resolve an issue, please contact customer service for assistance.
