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, suitable for simple loads like fans. Sensorless Vector Control (SVC) is a more advanced algorithm that provides precise control over the motor’s torque without an encoder. It delivers high starting torque at very low speeds (150% at 0.5Hz) and better speed stability, making it ideal for machinery and conveyors.
2. How do I select the right VFD model for my motor?
The selection of a VFD primarily depends on your motor’s rated power, voltage, and application. For the model EV510A-0022G-T4, “0022” indicates it’s for a 2.2kW motor, “G” stands for general-purpose load (constant torque), and “T4” signifies a three-phase 380V input. Always ensure the VFD’s rated current (5.1A) is greater than or equal to your motor’s rated current.
3. What are the installation environment requirements for the inverter?
To ensure stable operation and a long service life, the inverter should be installed indoors in a well-ventilated area away from direct sunlight. The ambient temperature should be between -10°C and +40°C, with humidity below 95%RH and no condensation. The installation altitude should be below 1000 meters.
4. What happens if there is a momentary power outage?
This series of inverters features an “Instantaneous stop not stop” function (ride-through). In the event of a brief power grid voltage drop, the VFD can use the energy fed back from the motor to compensate for the voltage loss, allowing it to continue running for a short period and preventing production interruptions.
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. Ensure there is sufficient clearance around the unit for proper ventilation and heat dissipation.
Step 2: Main Circuit Wiring
- Connect the three-phase 380V AC power lines to the inverter’s input terminalsÂ
R,ÂS, andÂT(L1/L2/L3). - 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
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 terminalÂ
S1. - Connect the other end of the switch to the common terminalÂ
COM. - Set parameterÂ
P0-02(Command source selection) to “1” (Terminal command channel). - Set parameterÂ
P4-00(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 2.2kW)P1-02: Motor Rated Voltage (set to 380V)P1-03: Motor Rated CurrentP1-04: Motor Rated FrequencyP1-05: Motor Rated Speed
- For optimal vector control performance, perform a motor auto-tune. Set parameterÂ
P1-37(Motor auto-tuning method selection) to “2” (dynamic 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.
