EV210-0015G-S2: High-Torque Miniature Single Phase VFD | 1.5kW, 220V
Why Choose This 1.5 kW (2HP) 220V Single Phase VFD?
When panel space is as critical as performance, this specific 1.5 kW (2HP) VFD is the superior choice. While other 1.5kW drives (like the EV510A) offer more I/O, they are significantly larger. This 72mm-wide VFD is the solution for machine builders who must fit full vector control power into the tightest control cabinets.
- Better Low-Speed Performance: This drive isn’t just small; it’s powerful at low speeds. It delivers 150% torque at 0.25Hz , offering finer and more stable control for high-inertia starts (e.g., small grinders, textile machines) than standard general-purpose drives that only promise 0.5Hz.
- Cost-Effective for OEM Integration: For machine builders, the EV210’s focused feature set (built-in PID, Modbus)  and miniature footprint reduce total system cost. It provides the essential vector control and automation features without the expense or footprint of a larger, more complex inverter.
- Run a 2HP Motor from Your Wall: This is the perfect single phase VFD for 3-phase 1.5kW motor control, allowing you to run 2HP (or smaller) 220V 3-phase motors from a standard 220V single-phase supply.
Typical Application Fields
Machine Tools
Ideal for small grinders, lathes, and drilling machines as a compact machine tool VFD where the 72mm width allows for easy panel integration.
Textile & Wire Drawing
An excellent textile machine VFD or for wire drawing, where the high starting torque (150% at 0.25Hz) is critical for handling material tension and inertia from a near-stop.
Pumps and Fans
A smart choice for fan and pump VFD applications up to 1.5kW, using the built-in PID to maintain constant pressure or flow, all within a minimal footprint.

Frequently Asked Questions (FAQ)
- What is the main difference between the EV210-0015G-S2 and the EV510A-0015G-S2?The key difference is size and application focus. The EV210 is a miniature VFD (only 72mm wide)  designed for space-critical OEM applications. The EV510A is a larger general-purpose drive (112mm wide)  with more extensive I/O (e.g., 7 Digital Inputs vs. the EV210’s 4).
- Which 1.5kW drive has better low-speed torque: EV210 or EV510A?The EV210 series is optimized for high-torque starts at very low speeds, offering 150% torque at 0.25Hz. This is superior for high-inertia loads compared to the EV510A’s excellent 150% at 0.5Hz rating.
- How do I select the right VFD model for my 1.5kW motor?Selection depends on power, voltage, and application. In the model EV210-0015G-S2, “0015” indicates it’s for a 1.5kW motor, “G” stands for general-purpose load (constant torque), and “S2” signifies a single phase 220V input. Always ensure the VFD’s rated output current (7.0A 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 EV210-0015G-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 (at least 100mm) for ventilation. This drive’s 72mm width allows for tight installations.
- 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: Motor Rated Power (set to 1.5kW)
- P1-02:Â Motor Rated Voltage (e.g., 220V)
- P1-03: Motor Rated Current (e.g., 6.8A, use your motor’s value)
- P1-04:Â Motor Rated Frequency
- P1-05: Motor Rated Speed. For optimal vector control, perform an auto-tune. Set parameter P1-37 (Motor auto-tuning method) to “2” (dynamic) or “3” (static) and start the inverter.
- Step 5: Test RunAfter confirming all settings, turn on the main power. Close the external switch (X1 to COM). The motor should start. Open the switch, and the motor will stop.
Core Features & Advantages
