EV210-0022G-S2: High-Torque Miniature Single Phase VFD | 2.2kW, 220V
Why Choose This 2.2 kW (3HP) 220V Single Phase VFD?
When panel space is as critical as performance, this specific 2.2 kW (3HP) VFD is the superior choice. While other drives offer this power rating, the EV210-0022G-S2 is engineered for machine builders and retrofitters who need full vector control performance in the smallest possible package.
- Maximum Power, Minimum Space: The EV210-0022G-S2 provides 2.2kW (3HP) of power in a slim 72mm chassis. It’s the perfect solution for running 3HP (or smaller) three-phase motors from a 220V single-phase supply in crowded control cabinets.
- Superior Low-Speed Control: While many compact drives only offer basic V/F control, this model provides advanced sensorless vector control. This is essential for applications like machine tools, wire drawing, and small conveyors that need high torque from a standstill (150% at 0.25Hz).
- Integrated & Cost-Effective: By integrating features like a PID controller and RS-485 Modbus, this drive saves you money. You can automate simple pump or fan systems without needing an external PLC, reducing hardware cost, simplifying wiring, and saving space.
- Reliable Protection:Â The EV210 series features advanced overcurrent and overvoltage suppression algorithms, preventing nuisance trips during operation and keeping your machinery running reliably.

Frequently Asked Questions (FAQ)
- What is the main difference between the EV210 and EV510A series?The EV210 series is a miniature VFD, designed specifically for applications where installation space is extremely limited. This 2.2kW model is only 72mm wide. The EV510A is a high-performance general-purpose drive that is physically larger (the 1.5kW model is 112mm wide) and typically offers a more extensive set of I/O terminals (e.g., 7DI/2AI/2RO vs. the EV210’s 4DI/1AI/1RO).
- What does 150% torque at 0.25Hz mean for my application?This is a key feature of the EV210’s sensorless vector control (SVC). It means the drive can generate 1.5 times the motor’s rated torque when the motor is turning at only 0.25Hz (a near-standstill). This is critical for starting high-inertia loads (like a loaded conveyor or machine tool) smoothly and powerfully, without the motor stalling or the drive tripping on overcurrent.
- How do I select the right VFD model for my motor?Selection depends on your motor’s rated power, rated voltage, and application load type. In the model EV210-0022G-S2, “0022” indicates it’s for a 2.2kW motor, “G” stands for general-purpose load (suitable for constant torque applications like machine tools and conveyors), and “S2” signifies a single-phase 220V input. Always ensure the VFD’s rated output current (9.6A for this model) is greater than or equal to your motor’s nameplate rated current.
- Can I connect this VFD to a PLC or HMI?Yes. The EV210-0022G-S2 comes standard with a built-in RS-485 communication interface that supports the Modbus RTU protocol, allowing it to be easily integrated into a larger automation system for centralized control and monitoring.
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: InstallationMount the inverter vertically on a sturdy, non-flammable surface, such as a metal mounting plate inside a control cabinet. Ensure there is sufficient clearance around the unit (at least 100mm recommended) for proper ventilation and heat dissipation.
- Step 2: Main Circuit WiringConnect the Single Phase 220V AC power lines to the inverter’s input terminals R and S(L1). Connect the three wires of the 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 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. Set parameter P0-02 (Command source selection) to “1” (Terminal command channel). Set parameter P4-00 (X1 function selection) to “1” (Forward run).
- Step 4: Motor Parameter Setting & Auto-tuningUpon first power-up, accurately enter the following parameters from your motor’s nameplate :
- P1-01:Â Motor Rated Power (set to 2.2kW)
- P1-02:Â Motor Rated Voltage (e.g., 220V)
- P1-03:Â Motor Rated Current
- P1-04:Â Motor Rated Frequency
- P1-05: Motor Rated Speed. For optimal vector control performance, perform a motor auto-tune. Set parameter P1-37 (Motor auto-tuning method) to “2” (dynamic auto-tuning) or “3” (static auto-tuning) and start the inverter.
- Step 5: Test RunAfter confirming all wiring and parameter settings are correct, turn on the main power. Close the external switch connected between X1 and COM. The motor should start rotating in the forward direction. Open the switch, and the motor will stop according to the set deceleration time.
