EV210-0004G-S2: Compact High-Performance Vector VFD | 0.4kW, 220V
Why Choose This 0.4kW (0.5HP) 220V Compact Vector VFD?
Choosing the right drive is critical. This specific 0.4kW (0.5HP) VFD is the ideal solution when your application is too demanding for a basic mini-drive, but the installation space is too small for a full-sized vector drive.
- The “Compact Vector” Hybrid Advantage: This is the perfect hybrid drive. When a basic miniature AC drive (like the EV200, designed for “simple speed regulation” ) lacks the precision for your load, the EV210-0004G-S2 provides the advanced vector control you need in the compact form factor you want.
- Precision for Complex Micro-Machinery: This AC motor speed controller excels in applications beyond simple fans. Its vector control is essential for máquinas herramienta , bobinadoras textiles , o máquinas de envasado donde el motor debe mantener la velocidad y el par exactos bajo cargas variables.
- Quiet, Reliable Operation: The adjustable carrier frequency provides low noise operation , a critical feature for equipment installed in noise-sensitive environments like laboratories or small workshops.
- Cost-Effective Automation: By integrating PID and RS485 communication , this compact vector VFD can simplify your system design, eliminating the need for external controllers and reducing total system cost and complexity.

Preguntas más frecuentes (FAQ)
1. What is the main difference between the 0.4kW EV210 and the 0.4kW EV200 VFD?
The key difference is the control method and positioning. The EV200 is a “small inverter” designed for regulación sencilla de la velocidad. The EV210 is a “high-performance miniature inverter” that integrates advanced current vector control. Choose the EV200 for simple applications like small fans or basic conveyors. Choose the EV210 for applications needing precise speed, high starting torque, or stable control under load, such as machine tools or packaging.
2. Can I use this 0.4kW VFD for a CNC or machine tool spindle motor?
Yes, the EV210-0004G-S2 is an excellent choice for small machine tool spindles. Its sensorless vector control provides stable torque even at low speeds, which is crucial for cutting. Furthermore, its adjustable high-carrier frequency (up to 16.0KHz) ensures low noise operation , reducing the “whine” from the motor.
3. What is the benefit of the ‘speed tracking restart’ function?
This function allows the VFD to smoothly “catch” a motor that is already spinning (e.g., a fan coasting after a brief power outage) and return it to the set speed without a harsh start or tripping on overcurrent. This is critical for reliable, uninterrupted operation in automated systems.
4. How does the built-in PID controller work?
The built-in PID allows the VFD to automatically regulate motor speed to maintain a process variable. For example, you can connect a pressure sensor (as an analog input) and set a target pressure. The VFD will then speed up or slow down a small pump to perfectly maintain that pressure, all without needing an external PLC.
Guía de inicio rápido (How-To)
Advertencia: Los siguientes pasos son sólo una guía básica. Todos los trabajos eléctricos deben ser realizados por personal profesional cualificado. Antes de realizar cualquier cableado, asegúrese de que la alimentación principal esté completamente desconectada y espere al menos 10 minutos para que los condensadores internos del variador de frecuencia se descarguen por completo.
Paso 1: Instalación
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.
Paso 2: Cableado del circuito principal
- Conecte sus líneas de alimentación monofásicas de 220 V CA a los terminales de entrada S/L1 y T/L2 del inversor.
- Connect the three wires of your 0.4kW (0.5HP) three-phase asynchronous motor to the inverter’s output terminals U, V, and W.
- Conecte firmemente el cable de tierra al terminal PE (tierra de protección) del inversor.
Paso 3: Cableado del circuito de control (para arranque/parada básico de 2 cables)
- Conecte un extremo de un interruptor externo (o botón) al terminal de entrada digital X1.
- Conecte el otro extremo del interruptor al terminal común COM.
- (This setup uses X1 for a simple “Run” command in 2-wire mode).
Paso 4: Ajuste y configuración de los parámetros del motor
- Tras el primer encendido, ajuste los parámetros del variador de frecuencia para que coincidan con la placa de características del motor:
- Set P1-01 (Motor Rated Power) to 0.4 (kW).
- Ajuste P1-02 (Tensión nominal del motor) a 220 (V).
- Ajuste P1-03 (Corriente nominal del motor) según la placa de características de su motor.
- Ajuste P1-04 (Frecuencia nominal del motor) (por ejemplo, 50 ó 60 Hz).
- Ajuste P1-05 (Velocidad nominal del motor) (por ejemplo, 1440, 2800, etc.).
- Para activar el arranque/parada a 2 hilos del paso 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 performance, perform a motor auto-tune (set P1-37, see manual for details).
Paso 5: Prueba de funcionamiento
Después de confirmar todo el cableado y los ajustes, conecte la alimentación principal. Cierre el interruptor externo conectado entre X1 y COM. El motor debería arrancar y funcionar en dirección de avance. Abra el interruptor y el motor desacelerará y se detendrá.
