EV200-0040G-T4: High-Power 4.0kW (5.5 HP) Industrial Vector AC Drive
Why Choose This 4.0 kW (5.5 HP) 3-Phase VFD?
Simplified Braking Setup: For applications like saw mills or flywheels where coast-to-stop is too slow, the built-in braking unit allows you to add braking capability cheaply and easily, improving cycle times and safety.
Maximize Cabinet Space: Engineers can fit more 4.0kW drives into a standard electrical cabinet compared to traditional wide-body inverters. This is ideal for retrofit projects where space is tight.
Precision Motor Control: Whether driving a 4kW spindle on a CNC router or a high-pressure water pump, the vector control algorithm ensures speed stability and rapid torque response to load changes.
Energy Efficiency: For fan and pump applications, the VFD optimizes motor speed to match demand, potentially reducing energy consumption by 30-60% compared to valves or dampers.
Protective Features: Offers a full suite of protections, including Phase Loss, Overcurrent, Overvoltage, Overheat, and Motor Overload, ensuring your critical 5.5HP motors are safeguarded against electrical faults.

Frequently Asked Questions (FAQ)
1. Does the EV200-0040G-T4 require an external braking chopper?
No. Unlike the smaller EV200 models, the 4.0kW model has a built-in braking unit. You do not need to buy a separate braking module. You can wire a dynamic braking resistor directly to the terminals labeled PB and (+) to enable fast stopping.
2. Can I use this VFD with a single-phase 220V input?
No. The T4 in the model number indicates Three-Phase 380V Input. Connecting it to single-phase 220V will result in an Undervoltage (FU09) fault, and the device will not function. For single-phase applications, please check if a 220V model is suitable for your motor.
3. What size braking resistor should I use?
For a 4.0kW application, a typical braking resistor specification would be approximately 400W 100Ω or 500W 75Ω. Please consult the user manual’s specific recommendation table or your detailed engineering requirements based on the braking duty cycle.
4. How do I set up the VFD for a 4kW Spindle?
For a high-speed spindle (e.g., 400Hz):
Set P0-10 (Max Frequency) to 400.00Hz.
Set P0-03 (Frequency Source) to 1 (Keypad) or 2 (Analog Potentiometer).
Set P0-02 (Command Source) to 1 (Terminal) if using external switches.
Crucial: Set P1-01 to 4.0kW, P1-02 to 380V, P1-04 to 400Hz (or spindle rated Hz), and P1-05 to the spindle’s rated RPM (e.g., 24000). Run Auto-tuning (P1-37).
Quick Start Guide (How-To)
Warning: 380V is lethal. Disconnect the power and wait 10 minutes before wiring.
Step 1: Mechanical Installation
Mount the VFD vertically in your cabinet. Ensure at least 100mm clearance above and below for airflow. Side-by-side mounting is permitted.
Step 2: Main Circuit Wiring
Input: Connect 3-Phase 380V supply to R, S, T.
Output: Connect 3-Phase 4.0kW motor to U, V, W.
Braking (Optional): Connect braking resistor to PB and (+).
Ground: Connect PE to earth.
Step 3: Parameter Setup.
Power on the unit. Press PRG to access parameters:
P1-01: Set to 4.0 (Motor Power).
P1-02: Set to 380 (Voltage).
P1-03: Set to 9.0 (Current – Verify on Motor Nameplate).
P1-04: Set to 50.00 (Frequency).
P1-05: Set to 1440 (RPM).
Step 4: Auto-Tuning
Set P0-01 = 0 (Vector Control).
Set P1-37 = 1 (Static Auto-tuning) or 2 (Rotary Auto-tuning, if motor is disconnected from load).
Press RUN. The drive will measure motor characteristics to optimise torque.
Step 5: Run Test
Set P0-02 = 0 (Keypad Control).
Use the potentiometer or Up/Down keys to set a low frequency (e.g., 5Hz).
Press RUN and check motor rotation direction.
Core Features & Advantages
Built-in Braking Unit: A key upgrade from smaller models, this 4.0kW drive integrates the braking chopper IGBT internally. You can simply connect an external braking resistor to terminals PB and (+) to achieve fast, controlled stopping of high-inertia loads, saving cost and panel space.
High Power Density (Narrow Body): Despite its 5.5HP capacity, the drive retains the book-style narrow body design. This allows for high-density side-by-side installation in control cabinets, significantly reducing the enclosure size required for multi-axis systems like textile machines or packaging lines.
Advanced Sensorless Vector Control (SVC): Capable of outputting 150% rated torque at 0.5Hz (P0-01=0), ensuring powerful low-speed performance for demanding machinery like extruders or mixers that need to start under load.
Independent Air Duct Cooling: The straight-through vertical air duct design completely isolates cooling air from the electronic components (PCB). This is crucial for longevity in dusty environments like woodworking shops or ceramic factories, preventing short circuits caused by conductive dust.
Robust 380V Grid Adaptability: Engineered for industrial stability, it handles input voltage fluctuations (380V ±15%) and includes Automatic Voltage Regulation (AVR) to ensure the motor receives constant voltage even if the grid is unstable.
Comprehensive I/O & Control: Features 4 Digital Inputs, 1 Analog Input (0-10V/0-20mA), and 1 Relay Output, along with RS485 Modbus communication for seamless integration into PLC-controlled industrial automation networks.
