EV200-0075G-T4: 7.5kW (10 HP) Heavy-Duty Industrial AC Drive
Why Choose This 7.5 kW (10 HP) 3-Phase VFD?
Cost-Effective Heavy Duty Control: Provides the robust performance required for 10HP motors without the high cost and bulk of larger cabinet drives. It effectively replaces contactors and soft starters while adding variable speed benefits.
Dynamic Braking Capability: The integrated braking unit makes it ready for dynamic loads immediately—just add a resistor. This eliminates the complexity and cost of sizing external chopper modules.
Energy Efficiency: For variable torque applications like 10HP ventilation fans or water pumps, the VFD adjusts motor speed to match demand, potentially reducing energy consumption by 30-60%.
Process Optimisation: With built-in PID control, it can automatically regulate pressure or flow in pumping systems. The Simple PLC function allows for automated cyclic operations in machinery like industrial washers.
Reliability: Comprehensive protection features, including Output Phase Loss, Overcurrent, Overvoltage, and Thermal Overload, ensure continuous operation and protect your expensive 10HP motors.

Frequently Asked Questions (FAQ)
1. Does the EV200-0075G-T4 have a built-in braking unit?
Yes. All EV200 models rated 3.7kW and above come with a built-in braking unit. You can directly connect a dynamic braking resistor to the PB and (+) terminals. This is highly recommended for high-inertia loads like centrifuges to prevent Overvoltage (FU06) faults during deceleration.
2. What size braking resistor do I need for 7.5kW?
A common specification for a 7.5kW drive would be around 800W 75Ω or similar. Please consult the specific braking resistor selection table in the user manual or contact support for exact sizing based on your braking duty cycle.
3. Can I use this VFD with a Single-Phase 220V input?
No. This is a Three-Phase 380V input drive. Connecting it to single-phase 220V will not work and may trigger under-voltage faults. For single-phase applications, you typically need a specialized drive or a phase converter, as standard single-phase input VFDs rarely go up to 7.5kW.
4. What protection features does it have?
It includes comprehensive motor and drive protection: Overcurrent, Overvoltage, Undervoltage, Output Phase Loss, Output Short Circuit, Overheat, and Motor Overload. These features ensure the safety of your 10HP motor and the drive itself.
Quick Start Guide (How-To)
Warning: High Voltage 380V! Disconnect the power and wait 10 minutes before wiring.
Step 1: Installation
Mount the VFD vertically on a sturdy metal backplate. Ensure sufficient clearance for the cooling fans to operate effectively.
Step 2: Wiring
Input: Connect 3-Phase 380V supply to R, S, T.
Output: Connect 10HP motor to U, V, W.
Braking (Optional): Connect braking resistor to PB and (+).
Ground: Connect PE to earth.
Step 3: Parameter Setup
Power on. Press PRG to configure motor data:
P1-01: Set to 7.5 (Motor Power).
P1-02: Set to 380 (Voltage).
P1-03: Set to 17.0 (Current – Check 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).
Press RUN. The drive will perform a static test to optimise torque.
Step 5: Operation
Set P0-02 = 1 for Terminal Control (Switch) or 0 for Keypad Control.
Set P0-03 = 2 to use the external potentiometer (AI1) for speed reference.
Core Features & Advantages
High Power Density (10 HP): Delivers full 7.5kW power in a compact chassis that saves valuable control cabinet space compared to traditional general-purpose drives. Supports side-by-side installation, optimizing panel layout for multi-drive systems.
Built-in Braking Unit: Standard on this model, the internal braking chopper allows for the direct connection of external braking resistors. This is essential for managing the regenerative energy from high-inertia loads like centrifuges or flywheels during rapid deceleration.
Powerful Vector Control (SVC): Features advanced current vector algorithms (P0-01=0) to provide 150% starting torque at 0.5Hz. This ensures a reliable startup for heavy-friction machinery such as loaded conveyor belts or crushers.
Independent Air Duct Cooling: The vertical straight-through air duct design physically isolates the cooling airflow from the electronic components. This protects the PCB from conductive dust and oil mist, making it highly durable in environments like textile mills and stone processing plants.
Robust 380V Input Handling: Designed for industrial grids, it accepts 380V ±15% input voltage and features Automatic Voltage Regulation (AVR) to maintain a stable output to the motor even during grid fluctuations.
Comprehensive I/O & Communication: Equipped with 4 Programmable Digital Inputs, 1 Analog Input, 1 Relay Output, and RS485 Modbus communication, facilitating seamless integration into PLC-controlled automation lines.
