Frequently Asked Questions (FAQ)
1. What is the difference between the 0.75kW EV210 and the 0.75kW EV200 VFD?
The key difference is the control method. The EV200 is a “small inverter” designed for simple speed regulation. The EV210 is a “high-performance miniature inverter”  that integrates advanced current vector control. Choose the EV200 for simple applications like small fans. Choose the EV210 for applications needing precise speed, high starting torque, or stable control under load, such as machine tools or packaging.
2. Why is the Rated Input Current (8.2A) so much higher than the Output Current (4.0A)?
This is normal for a single-phase input VFD. The drive draws power from a single AC phase (creating 8.2A of input current) and uses it to create a balanced three-phase output (at 4.0A per phase) for the motor. Always size your input-side wiring and breakers for the 8.2A input rating.
3. Does this 0.75kW VFD require an external braking resistor?
It depends on your application. If you need to stop a high-inertia load quickly, you will need one. The recommended specification for the EV210-0007G-S2 is an 80W, 150Ω resistor. This connects to terminals P+ and PB. For light-duty applications, DC braking (parameter P6-11)  may be sufficient.
4. Can I use the built-in PID to control a 1HP water pump?
Yes. The built-in PID controller is perfect for this. You can connect a 0-10V or 0-20mA pressure sensor to the analog input (AI)Â Â and set a target pressure. The VFD will automatically adjust the pump’s speed to maintain that pressure, which is also highly energy-efficient.
Quick Start Guide (How-To)
Warning:Â The following steps are a basic guide only. All electrical work must be performed by qualified professional personnel. Before any wiring, ensure the main power is completely disconnected and wait at least 10 minutes for the internal capacitors of the VFD to fully discharge.
Step 1: Installation
Mount the VFD vertically on a sturdy, non-flammable surface (like a metal backplate) or a DIN rail in a well-ventilated cabinet. Ensure sufficient clearance for airflow. The compact 72mm width allows for high-density, side-by-side installation.
Step 2: Main Circuit Wiring
- Connect your Single Phase 220V AC power lines to the inverter’s input terminals S/L1 and T/L2.
- Connect the three wires of your 0.75kW (1HP) three-phase asynchronous motor to the inverter’s output terminals U, V, and W.
- Securely connect the ground wire to the inverter’s PE (Protective Earth) terminal.
Step 3: Control Circuit Wiring (for Basic 2-Wire Start/Stop)
- Connect one end of an external switch (or button) to the digital input terminal X1.
- Connect the other end of the switch to the common terminal COM.
Step 4: Motor Parameter Setting & Configuration
- Upon first power-up, set the VFD parameters to match your motor’s nameplate :
- Set P1-01 (Motor Rated Power) to 0.75 (kW).
- Set P1-02 (Motor Rated Voltage) to 220 (V).
- Set P1-03 (Motor Rated Current) based on your motor’s nameplate.
- Set P1-04 (Motor Rated Frequency) (e.g., 50 or 60 Hz).
- Set P1-05 (Motor Rated Speed) (e.g., 1440, 2800, etc.).
- To enable the 2-wire start/stop from Step 3:
- Set P0-02 (Command source) to “1” (Terminal command channel).
- Set P4-00 (X1 function selection) to “1” (Forward run).
- For optimal vector control, perform a motor auto-tune (set P1-37, see manual for details).
Step 5: Test Run
After confirming all wiring and settings, turn on the main power. Close the external switch connected between X1 and COM. The motor should start and run in the forward direction. Open the switch, and the motor will decelerate and stop.
