EV200-0004G-S2: Compact Single Phase VFD | 0.4kW, 220V
Why Choose This 0.4 kW (0.5HP) 220V Single Phase VFD?
Choosing the right drive is crucial for performance and reliability. This specific 0.4 kW (0.5HP) VFD is the ultimate space-saver and the ideal choice for straightforward applications.
Designed for Tight Spaces: Its key feature is the ultra-compact narrow body design, which is 45% smaller than previous models. It also supports side-by-side installation, making it perfect for crowded control cabinets where space is a premium.
Simple and Efficient: While the EV510A series offers complex, high-count I/O, the EV200 is designed for simple speed regulation. Its streamlined 4 DI / 1 AI / 1 Relay setup provides all the necessary control for small automated machinery without unnecessary complexity or cost.
Reliable Vector Performance: Despite its small size, it delivers true vector control performance, providing excellent low-speed high-torque (150% at 0.5Hz)  for reliable startups, far surpassing simple V/F control.
No Braking Unit: This model does not include a built-in braking unit, as it is part of the 0.75-2.2kW range, which is designed without them, making it a cost-effective choice for applications that do not require rapid deceleration.

Frequently Asked Questions (FAQ)
1. What is the difference between V/F control and Sensorless Vector Control (SVC)?
V/F control is a basic method for motor speed regulation. Sensorless Vector Control (SVC) is more advanced, providing precise speed and torque control. The EV200 uses SVC to deliver high starting torque (150% at 0.5Hz), which is much better for starting loads than basic V/F.
2. Does the EV200-0004G-S2 have a built-in braking unit?
No. The EV200 series states that models from 0.75kW to 2.2kW do not have a built-in braking unit, and this 0.4kW model follows that design. An external braking resistor would be required for applications needing fast deceleration.
3. What is the key difference between the EV200 and EV510A series?
 The EV200 is designed for simple speed regulation and ultra-compact size, featuring a narrow body that is 45% smaller and allows side-by-side installation. Its I/O is simplified (4 DI, 1 AI, 1 Relay). The EV510A series is a higher-performance drive with a much larger, more flexible I/O (7 DI, 2 AI, 2 AO, 2 Relay)  for more complex automation tasks.
4. Can this VFD be installed in a small cabinet with other drives?
Yes. The EV200 features independent air ducts for efficient cooling and is specifically designed to be installed side-by-side with other units, making it ideal for saving space in power distribution cabinets.
Quick Start Guide (How-To)
Warning: 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 discharge fully.
Step 1: Installation
Mount the inverter vertically on a sturdy, non-flammable surface, such as a metal mounting plate. Ensure there is sufficient clearance for heat dissipation. Side-by-side installation is permitted.
Step 2: Main Circuit Wiring
Connect the single-phase 220V AC power lines to the inverter’s input terminalsÂ
R/L1Â andÂS/L2.Connect the three wires of the three-phase asynchronous motor to the inverter’s output terminalsÂ
U,ÂV, andÂW.Securely connect the ground wire to the inverter’sÂ
PEÂ (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 terminalÂ
S1.Connect the other end of the switch to theÂ
COMÂ terminal.Set parameterÂ
P0-02Â (Command source selection) to “1” (Terminal command channel).Set parameterÂ
P4-00Â (S1 function selection) to “1” (Forward run).
Step 4: Motor Parameter Setting & Auto-tuning
Upon first power-up, accurately enter the following parameters from your motor’s nameplate:
P1-01: Motor Rated Power (set to 0.4kW)ÂP1-02: Motor Rated Voltage (set to 220V)ÂP1-03: Motor Rated Current (e.g., 2.3A)ÂP1-04: Motor Rated FrequencyÂP1-05: Motor Rated SpeedÂ
For optimal vector control performance, perform a motor auto-tune. Set parameterÂ
P1-37Â (Motor auto-tuning) to “2” (dynamic auto-tuning) or “3” (static auto-tuning) and start the inverter.
Step 5: Test Run
After confirming all wiring and parameter settings are correct, turn on the main power. Close the external switch connected between S1 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.
