    Tips: Single phase 220V to three phase 380V VFD features

    • Product features

    1-phase 220V input to 3-phase 380V output VFD adopts AC-DC circuit structure and uses SPWM modulation control technology to convert ordinary 1-phase 220V power to industrial 3-phase 380V power. It is suitable for 3-phase asynchronous motors with an output phase angle of 120°, which fully satisfies the motor use standard and is suitable for all types of motor loads. The single phase to three phase VFD solves the inconvenience of production in some areas due to 3-phase power restrictions, and also solves the needs of some users who cannot apply to 3-phase power due to site restrictions.

    • Technical features
    1. Ordinary utility 220V input, eliminating the cumbersome procedures of applying for 3-phase power and various labor costs and various hidden costs.
    2. The output uses industrial 3-phase power, but is billed according to the civilian 1-phase power, which is economical.
    3. Core components are imported devices, stable performance, long service life.
    4. Safe and reliable, the input 1-phase power and output 3-phase power completely electrical isolation.
    5. Input wide voltage range design, to adapt to the work environment of the general low utility voltage in various regions.
    6. Output protection function is perfect, there are over voltage, overload, over temperature, short circuit, over current and other kinds of protection.

    This video is about how to use buttons to run single-phase VFD of three-phase motors.

    The video shows the parameter setting methods for the V/F control mode and vector control mode of single-phase to three-phase VFD.

    This video provides insights into the wiring process for converting single-phase to three-phase VFD, specifically from 220V to 380V.

    Existing reviews of 15 hp VFD, 1-Phase 220V to 3-Phase 380V VFD
    we have a new error code
    Now we have a new error code. E-01. Can you please give some direction on how to fix that?
    From: Owens | Date: 28/11/2023

    E-01 error code is VFD overcurrent protection, indicating that the motor is heavily loaded. Does this fault occur when the VFD is started or does it occur occasionally during operation? You can try to modify the acceleration and deceleration time P0.12=P0.13=20, P5.00=2 or 3 (V/F curve setting). If you still have problems, please provide us with a picture of the motor nameplate and a video for further confirmation.  You can send us the large video file via
    Do you have a wiring schematic?
    Now we have taken: single-phase 208V circuit: 25A*2.5=62.5A, and 45A*2.5=112A
    The ampacity is higher, but now its reading 760 Volts, Not 380 Volts like it was.
    Do you have a wiring schematic? Or do you know what is causing the higher voltage to occur?

    ATO Responded
    We do not think that the VFD input voltage will be 220V and the output voltage will reach 760V.  Could you use a multimeter to measure the actual voltage at the VFD input/output terminals and provide us with photos of the measurement readings for further confirmation? Of course, it would be better if you could provide a video of the measurement. You can send us the large video file via

    Regarding the wiring of the VFD, the 220V input voltage is connected to the R-T terminal (the terminal S with the screw removed is not used), and the U, V, and W terminals are connected to the three-phase motor.
    Used to power CNC Spindle
    Used one of these to power my 380V CNC spindle with variable speed controlled by the CNC computer via VI 0-10V signal on SVC. So far so good. Good when you have an imported machine that was wired for 380V three phase. Customer service was helpful as well.

    Why we are getting this error code?
    We recently hooked up 2 machines, and they are throwing error codes E26.
    we took a single phase 208V 25A and a single phase 208V 45A circuit to the one that calls for it. We don’t understand why we are getting this error code.

    E26 is a current limit fault code.
    First, we want to confirm whether the E26 code displayed by the VFD occurs when the motor is connected and running, or whether the VFD appears when running the VFD without load.
    Please confirm whether the VFD can display normally and start normally if it is powered alone.
    Note: For the 1-Phase 220V to 3-Phase 380V VFD you purchased, the input side current capacity of the VFD is required to be 2.5 times the rated output current of the VFD.
    This means that the single-phase 208V 25A and single-phase 208V 45A circuits you are using do Not have enough capacity.
    You must use a single-phase 208V circuit: 25A*2.5=62.5A, and 45A*2.5=112A.
    What is the correct way to ground the VFD?
    I recently purchased a GK3000-CS0110G and I'm wondering what's the correct way to ground the unit.
    The main earthing circuit terminal is not electrically connected to the earth plate at the back of the unit or to the PE grounding terminal on C2 terminal block on the PCB.
    I would have expected all three to be electrically connected. Is this a defect? If not a defect, what is the correct way to ground the unit?
    From: antony | Date: 20/07/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Regarding the correct grounding of the VFD, the grounding cable at the PE end must not borrow the grounding wire of other equipment and must be directly connected to the grounding plate.
    The PE grounding terminal is mainly to prevent the internal leakage current of the VFD and is not directly connected to the internal PCB board. This grounding design is not questionable.
    You just need to connect the VFDs and motor's grounds individually to the grounding panel.
    Hope my explanation is able to assist you. Please feel free to let us know if you have any further questions.
    How to use VFD?
    For my application I need to have maximal torque (that is why I chose to run in senseless vector control mode ). What settings do I need to get the maximum torque at low RPM for your 1-phase drives?
    From: Cookster | Date: 08/10/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Our 1-phase driver is not suitable for running a single-phase motor under low speed and low voltage, which will lead to heating of single-phase motor. Generally, we suggest that the starting frequency should be set above 40Hz.
    VFD products recommended by ATO
    I need a VFD recommendation. I have a 3 phase motor. I need to run off of 220v single phase and the motor name plate is listed as follows 1725 rpm 208-230/460 6.0/3.0 amps 60 hertz 2 HP. What do your recommend?
