Frequently Asked Questions (FAQ)
1. Do I need an external braking module for this 5.5kW VFD?
No. The EV200-0055G-T4 comes with a built-in braking unit. You do not need a separate chopper module. You only need to connect an external dynamic braking resistor to the PB and (+) terminals to enable fast braking for high-inertia loads like saws or centrifuges.
2. Can I run a 5.5kW motor on single-phase 220V with this drive?
No. This model (T4) requires a Three-Phase 380V input. It cannot step up single-phase 220V to 380V. If you only have single-phase power, you would need a specific single-phase input VFD (usually limited to lower horsepower) or a rotary phase converter before the drive.
3. What is the “Narrow Body” advantage?
The 85.5mm width is significantly slimmer than standard 7.5HP drives. This allows for side-by-side mounting with zero clearance, meaning you can fit more drives into a smaller, less expensive control cabinet. This is ideal for multi-motor machines like textile or packaging lines.
4. How do I set up PID control for a water pump?
Connect your pressure sensor (e.g., 4-20mA) to the AI1 terminal (ensure Jumper J4 is set to Current). Set P0-03=8 (PID Control). Set PA-01 to your desired pressure setpoint (as a %), and PA-02=0 (AI1 Feedback). The VFD will automatically adjust the 7.5HP pump speed to maintain constant pressure.
Quick Start Guide (How-To)
Warning: 380V is lethal. Disconnect the power and wait 10 minutes before wiring.
Step 1: Installation
Mount the VFD vertically on a DIN rail or backplate. Ensure the cooling fans at the bottom are not blocked.
Step 2: Wiring
Input: Connect 3-Phase 380V supply to R, S, T.
Output: Connect the 7.5HP 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 enter the menu:
P1-01: Set to 5.5 (Motor Power).
P1-02: Set to 380 (Voltage).
P1-03: Set to 13.0 (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).
Press RUN. The drive will energise the motor to measure resistance.
Step 5: Operation
Set P0-02 = 1 (Terminal Control) for external switches or 0 for the Keypad.
Use the potentiometer or external signal to adjust speed.
Core Features & Advantages
Built-in Braking Unit: Unlike smaller drives that require external modules, the 5.5kW model integrates the braking chopper. You can directly connect a braking resistor to terminals PB and (+) for rapid deceleration of heavy loads like centrifuges or saw blades, improving safety and cycle times.
Ultra-Narrow High-Density Design: At just 85.5mm wide, this 7.5HP drive allows for high-density side-by-side installation. This critical space-saving feature enables engineers to fit more drives into standard control cabinets, reducing enclosure costs for multi-axis systems.
High-Torque Sensorless Vector Control (SVC): Delivers 150% starting torque at 0.5Hz, ensuring powerful, stall-free startups for heavy friction loads such as loaded conveyors or extruders.
Independent Air Duct Cooling: The vertical straight-through air duct isolates cooling air from the PCB. This protects sensitive electronics from conductive dust and oil mist found in textile mills, woodworking shops, and stone fabrication plants.
Robust 380V Grid Adaptability: Designed to handle industrial voltage fluctuations (380V ±15%) with built-in AVR (Automatic Voltage Regulation), ensuring consistent motor performance even on unstable power grids.
Advanced Process Control: Features a built-in PID controller for closed-loop pressure or flow regulation, and a Simple PLC for automating multi-step speed cycles (e.g., wash/spin cycles in laundry machines) without external PLCs.
