4. Installation and Wiring
4.1 Physical Installation
The VFD is designed for integrated installation. Ensure it is mounted in a location with sufficient space for ventilation and easy access to controls and wiring terminals. The dimensions are approximately 17 x 12 x 9 cm (L x W x H).
Image 4.1: Control Panel Dimensions.
4.2 Electrical Wiring
The Jadeshay VFD requires a single-phase 220V input and provides a three-phase 220V output. It is crucial to connect the motor correctly. If the original three-phase motor was configured for 380V, it must be reconfigured to a delta connection for 220V operation.

Image 4.3: Detailed Technical Wiring Diagram.
Image 4.4: Control Panel and Triangle Wiring Configuration.
Wiring Steps:
- Connect the single-phase 220V AC input to the 'AC' terminals on the VFD.
- Connect the ground wire to the 'FG' (Frame Ground) terminal.
- Connect the three-phase motor to the 'U', 'V', and 'W' output terminals.
- Ensure the motor is configured for 220V operation (typically delta connection for 380V motors).
- For external control, refer to the detailed wiring diagram for programmable input terminals (X1-X4, FWD, REV), analog input (AI), and relay output (FA, FB).
- A 5.1 kΩ 2W potentiometer is recommended for external speed control.
Note: The JH-100 series (which this model belongs to) does not provide FWD, REV, +10V DC, AI, AOUT, FA, and FB ports. Their corresponding functions and parameters are invalid. JH-100 also does not have RS485 function.
5. Operating Instructions
5.1 Powering On
After ensuring all wiring is correct and secure, apply single-phase 220V power to the VFD. The power indicator light will illuminate, and the digital display will show the default frequency or last set value.
5.2 Speed Adjustment
- Using the Potentiometer: Rotate the knob on the front panel to adjust the output frequency, thereby controlling the motor speed. The scale typically ranges from 0 to 10.
- Using Digital Keys: For precise adjustments or specific parameter settings, use the Up (▲) and Down (▼) buttons after entering the parameter setting mode via the PROG button.
5.3 Starting and Stopping the Motor
- Start: Press the RUN button to start the motor. The motor will accelerate to the set speed according to the configured acceleration time.
- Stop: Press the STOP button to stop the motor. The motor will decelerate and stop according to the configured deceleration time.
5.4 Forward and Reverse Operation
- Forward: After setting the desired speed, press the RUN button. The forward rotation indicator will light up.
- Reverse: Press the REV button to run the motor in reverse. The reverse indicator will light up.
5.5 Parameter Settings

7. Troubleshooting
This section provides solutions to common issues you might encounter with your VFD.
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start | No power, incorrect wiring, STOP button pressed, parameter error. | Check power supply. Verify wiring connections. Ensure STOP button is not active. Check motor parameters. |
| Motor speed is incorrect | Potentiometer setting, frequency parameter incorrect. | Adjust potentiometer. Check and set frequency parameters (e.g., maximum frequency, base frequency). |
| VFD displays an error code | Overvoltage, undervoltage, overcurrent, overload, short-circuit. | Refer to the VFD's specific error code list (if available in the full manual) for detailed solutions. Often, pressing the STOP button can reset the VFD after resolving the fault. |
| VFD overheats | Poor ventilation, excessive load, high ambient temperature. | Ensure proper airflow around the VFD. Reduce motor load if possible. Check ambient temperature. |
If the problem persists after attempting these solutions, please contact customer support.
