- Safety & Durability Redefined: Incorporates a 10-layer protection system against overcurrent, overload, overvoltage, and phase loss. The circuit board is treated with triple-proof paint for enhanced longevity.
- Efficient Heat Dissipation: Equipped with a powerful cooling fan and a multi-sided, multi-hole design to ensure optimal ventilation and low noise operation during extended use.
- Master of Versatility: Suitable for driving 3-phase motors in various machinery, including compressors, lathes, fans, and milling machines.
2. Safety Precautions
Adherence to the following safety guidelines is crucial to prevent injury, property damage, and ensure the proper functioning of the VFD:
- Always disconnect power before performing any wiring or maintenance. Failure to do so may result in severe injury or death.
- Never connect the U/V/W output terminals directly to an AC power supply. This will cause irreparable damage to the inverter.
- Do not install the inverter on flammable surfaces or near flammable materials to avoid fire hazards.
- Ensure the ground terminal of the inverter is properly and securely grounded.
- Avoid installing the VFD in environments with explosive gases to prevent the risk of explosion.
- Only qualified professionals should perform wiring and internal maintenance. The converter contains high voltage, and unauthorized opening of the shell is prohibited.

4. Setup and Installation
Wiring Instructions:
Proper wiring is essential for safe and correct operation. Refer to the diagram below for connecting the VFD.
Figure 4.1: Wiring diagram for the VEVOR AT1-2200X VFD.
| Terminal Label | Function Description |
|---|---|
| L, N | Single phase AC 220V input terminal |
| U, V, W | Output terminal connect to three phase motor |
| GND | Grounding terminal |
Important Considerations:
- Ensure all connections are secure and properly insulated.
- Verify that the input voltage matches the VFD's specifications (AC 220-240V single phase).
- The VFD does not support external braking resistors.
- For heavier motor loads, it is recommended to select a VFD with a higher power rating than the motor for optimal performance.
Mounting:
The VFD is designed for wall mounting. Ensure the mounting surface is stable and capable of supporting the unit's weight. Allow adequate clearance around the VFD for ventilation and heat dissipation.
5. Operation
Basic Controls:
- Starting the Motor: Press the RUN button to start the motor.
- Stopping the Motor: Press the STOP/RESET button to stop the motor.
- Adjusting Speed: Rotate the Speed Adjustment Knob to increase or decrease the motor's operating frequency.
- Changing Direction: Use the FWD/REV key to switch between forward and reverse rotation.
- Display Information: Press the DISP key to cycle through various display parameters such as output frequency, current, voltage, etc.
Programming Parameters:
The VFD offers extensive programming capabilities to fine-tune its operation for specific applications. To enter programming mode, press the PROG key. Use the Up/Down keys to navigate through parameters and the FUNC/DATA key to select and confirm settings. Refer to the detailed parameter list in the complete user manual for specific adjustments, such as setting the motor's rated frequency (e.g., 60Hz for US motors), acceleration/deceleration times, and other advanced functions.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your VFD.
- Cleaning: Periodically clean the exterior of the VFD with a soft, dry cloth. Ensure ventilation openings are free from dust and debris to prevent overheating.
