EV210-0007G-T4: High-Torque Compact 3-Phase 380V VFD | 0.75kW, 1HP
Why Choose This 0.75kW (1HP) 380V 3-Phase VFD?
This specific 0.75kW 380V VFD is the specialized solution for low-power industrial applications that demand high performance, not just basic speed control.
- Precision for Small Industrial Motors: While many VFDs focus on high horsepower, the EV210-0007G-T4 is optimized for 0.75kW (1HP) 3-phase 380V motors. It provides advanced sensorless vector control, offering precision torque regulation far superior to basic V/F control.
- Better Low-Speed Performance: This model provides 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.
- Space-Saving 87mm Industrial Chassis: Its compact 87mm width saves valuable DIN rail space in crowded industrial panels, allowing for higher-density machine designs compared to bulkier drives.
- Integrated & Cost-Effective: Use the built-in PID  for simple, standalone fan or pump control, or connect it to your central PLC using the standard RS485 Modbus. This integration reduces hardware cost and simplifies system design.

Frequently Asked Questions (FAQ)
- What is the difference between an S2 and a T4 model VFD?The model code indicates the input power supply. S2 models (like the EV210-0015G-S2) are for Single-Phase 220V power. T4 models, like this EV210-0007G-T4, are designed for Three-Phase 380V industrial power.
- What is the output current of the EV210-0007G-T4?The rated output current for this model is 2.1 Amps, designed to match a 0.75kW (1HP) 380V motor.
- Does this VFD have high starting torque for a 1HP motor?Yes. This drive features advanced sensorless vector control, allowing it to produce 150% of the motor’s rated torque at just 0.25Hz (a near-standstill). This is ideal for starting high-inertia loads.
- Can I use this 0.75kW VFD for a simple fan or pump?Absolutely. This model includes a built-in PID controller , making it perfect for simple, standalone fan or pump applications to maintain a constant pressure or flow without needing an external PLC.
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 87mm width allows for compact industrial installations.
- Step 2: Main Circuit WiringConnect the Three-Phase 380V AC power lines to the inverter’s input terminals R, S, and T (L1, L2, L3). 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 0.75kW)
- P1-02: Motor Rated Voltage (set to 380V)
- 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) 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
- Superior Low-Speed Torque: Implements advanced sensorless vector control (SVC) to achieve 150% rated torque at just 0.25Hz. This provides more powerful and stable control for high-inertia startups (like small grinders or textile winders) than standard drives rated at 0.5Hz.
- Compact 380V Industrial Design: With a width of only 87mm, this compact 380V VFD is ideal for saving panel space in industrial control cabinets, allowing for high-density machine designs.
- Robust Overload Capacity: Built for tough G-type (general purpose) loads, this 0.75kW 380V VFD withstands 150% of rated current for 60 seconds and 180% of rated current for 3 seconds, handling demanding industrial cycles.
- Integrated Automation Features: Includes a built-in PID controller for automating simple process control (like pumps and fans) and 16-segment multi-speed operation for complex programmed sequences.
- Flexible Industrial I/O: Standard on this 3-phase 380V VFD are 4 digital inputs, 1 analog input (V/I selectable), 1 relay output, and built-in RS485 Modbus VFD communication for easy system integration.
- Optimized Motor Matching: Features a motor parameter self-learning (auto-tune) function (P1-37) to precisely match the drive’s advanced control algorithm to your specific 0.75kW asynchronous motor, maximizing torque and efficiency.
