Frequently Asked Questions (FAQ)
What is the main difference between the EV210-0055G-T4 and the EV210-0022G-S2?
The key difference is the input power. The T4 model is for Three-Phase 380V industrial power. The S2 model is for Single-Phase 220V power, typically used to run 3-phase motors where only single-phase 220V is available.
How does this 5.5kW VFD compare to the EV510A-0055G-T4?
The EV210 is the specialist for compact spaces and low-speed torque. It is significantly narrower (87mm wide) than the 112mm EV510A and offers superior starting torque (150% at 0.25Hz) compared to the EV510A’s 0.5Hz. The EV510A offers more I/O terminals (7 DI vs 4 DI) for more complex general-purpose applications.
What is the output current of the EV210-0055G-T4?
The rated output current for this model is 13.0 Amps, designed to match a 5.5kW (7.5HP) 380V motor.
Can I use this VFD for a hard-starting load like an extruder or industrial mixer?
Yes. This drive is ideal for such applications. Its advanced sensorless vector control produces 150% of the motor’s rated torque at just 0.25Hz (a near-standstill) , providing the power needed to start constant-torque loads smoothly.
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 fully discharge.
Step 1: Installation
Mount the inverter vertically on a sturdy, non-flammable surface, such as a metal mounting plate inside a control cabinet. Ensure there is sufficient clearance (at least 100mm) for ventilation. This drive’s 87mm width allows for compact industrial installations.
Step 2: Main Circuit Wiring
Connect the Three-Phase 380V AC power lines to the inverter’s input terminals R, S, and T (L1, L2, L3). Connect the three wires of the three-phase asynchronous motor to the inverter’s output terminals U, V, and W. Securely connect the ground wire to the inverter’s PE (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 terminal X1. Connect the other end of the switch to the common terminal COM. Set parameter P0-02 (Command source selection) to “1” (Terminal command channel). Set parameter P4-00 (X1 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 5.5kW)
P1-02: Motor Rated Voltage (set to 380V)
P1-03: Motor Rated Current (e.g., 12.5A, use your motor’s value)
P1-04: Motor Rated Frequency
P1-05: Motor Rated Speed. For optimal vector control performance, perform a motor auto-tune. Set parameter P1-37 (Motor auto-tuning method) to “2” (dynamic) or “3” (static) and start the inverter.
Step 5: Test Run
After confirming all settings, turn on the main power. Close the external switch (X1 to COM). The motor should start. Open the switch, and the motor will stop.
