2. Safety Information
WARNING: Risk of electrical shock. Improper installation or operation can lead to serious injury or death.
- Read the user manual before operation.
- Risk of electrical shock. Wait 10 minutes after removing power before servicing. This allows capacitors to discharge.
- Wiring Matching: Connect the power and motor wires strictly according to the nameplate. Ensure that the phase sequence, voltage, and current do not exceed the standard ratings, and that grounding is firm.
- Parameter Setting: Before starting, adapt the rated parameters of the motor (power, speed, rated current) and adjust protection values (overcurrent, overheating, undervoltage) as needed.
- Start-up Operation: Avoid frequent start/stop or forward/reverse rotation with high carrier frequency. Use soft start/stop functions. Do not overload the VFD or operate at excessive speeds.
- Environmental Protection: Keep the VFD away from dust, oil stains, and water. Operate within the rated temperature range and ensure adequate ventilation and heat dissipation. Regularly clean filter screens.
- Fault Handling: If an alarm occurs, power off the unit first. Troubleshoot the wiring, motor, or load, then reset. Do not operate the VFD if it is faulty.
- Maintenance Operation: Always cut off power and discharge the VFD before performing any maintenance. Do not plug/unplug wiring or remove the cover while power is on. Regularly check wiring terminals for looseness or erosion.
- Adaptation Protection: For outdoor or corrosive environments, use a protective controller with waterproof cable seals to prevent foreign objects from entering the housing.

5. Setup
5.1. Wiring
Correct wiring is crucial for the safe and proper operation of the VFD. Refer to the diagram below and ensure all connections are secure and match your motor and power supply specifications.
Figure 5.1: Wiring diagram for the AE200 VFD.
- Power Input (R, S, T): Connect your main AC power supply here. For single-phase 220V input, typically connect to terminals R and S, leaving T unused. For three-phase 380V input, connect all three phases to R, S, and T respectively.
- Motor Output (U, V, W): Connect these terminals directly to the corresponding three-phase terminals of your AC motor.
- Brake Resistance (+PB): If your application requires dynamic braking for rapid deceleration, connect an appropriate braking resistor between the + and PB terminals.
- Ground (GND): Connect the ground terminal to a reliable earth ground. This is essential for safety and to prevent electromagnetic interference.
5.2. Mounting
Mount the VFD vertically on a flat, stable surface. Ensure there is sufficient space around the unit for proper ventilation and heat dissipation, especially above and below the VFD where cooling air flows. Avoid mounting in areas subject to excessive vibration, direct sunlight, or high humidity.

6.2. Basic Operation
- Power On: After ensuring all wiring is correct and secure, apply power to the VFD. The display will light up.
- Frequency Setting: Use the rotary knob to adjust the desired output frequency. The display will show the set frequency. Alternatively, frequency can be set via parameters.
- Start Motor: Press the RUN button. The motor will accelerate to the set frequency.
- Stop Motor: Press the STOP button. The motor will decelerate and stop according to the set deceleration time.
- JOG Operation: Press and hold the JOG button for momentary motor operation at a preset jog frequency. Release to stop.
6.3. Parameter Settings
The VFD has numerous parameters to customize its operation. To enter parameter programming mode, press the PROG button. Use the Up/Down arrows to navigate through parameter groups and individual parameters. Use the DATA button to select a parameter for editing, then use the arrows or knob to change its value. Press DATA again to confirm, and PROG to exit.

| OCD | Deceleration Overcurrent | Adjust the deceleration time appropriately (increase it). |
| OCN | Constant Speed Overcurrent | Check if the machine is normal and the input voltage is stable. |
| OU | Over-voltage | Adjust acceleration/deceleration time, check utility power. |
| LU | Undervoltage | Check if the utility power is normal (should be within 180V-240V for 220V units). |
| OH | Inverter Overheat | Check if the inverter's heat dissipation is normal (clean fan, clear vents). |
| EF | External Fault | Check if external sensors and inputs are normal. |
9. User Tips
- Frequency Range Verification: While the manual indicates an output frequency range of 0-400Hz for many parameters, some users have reported units operating within a 0-50Hz range. Always verify the actual operational frequency range of your specific model by checking the unit's display and detailed specifications upon receipt.
- Voltage and Phase Matching: Before powering on, double-check that the VFD's input voltage (Single Phase 220V or Three Phase 380V) and phase configuration correctly match your power supply and motor. Incorrect voltage or phase can damage the unit and motor.
- Grounding is Key: Always ensure a proper and secure earth ground connection for safety and to minimize electrical noise.
