    7.5 hp Single Phase to Three Phase VFD Details

    Tips: Difference between VSD, VFD, ASD, AFD

    The most correct term - according to IEEE and IEC - is ASD (Adjustable Speed Drive). This refers to the electronic equipment used to regulate the operating speed of the motor and driven equipment by controlling the frequency and voltage applied to the motor.
    NOTE that other terms in common use include (but are not limited to): VSD (Variable Speed Drive), AFD (Adjustable Frequency Drive), and VFD (Variable Frequency Drive), they are referring to the same motor drives, just different names.
    There is no difference between a VSD and VFD in terms of what it is designed to do. There MAY be differences based on specific internal components/construction and how it achieves that goal.

    Please recommend a suitable VFD
    I have a 220v 3 phase 5hp table saw at high rpm but only have a 220 single phase main power. I usually cut 4x4 or 2x6' lumber and would like to know hat VFD will be enough to handle my application. Thank you.

    Please send us a picture of your 5HP table saw nameplate label to sales (at) ato.com, and they will confirm the appropriate VFD model for you.
    Do I need a bigger VFD?
    The VFD does not seem capable of running the motor & pump. I tried increasing the acceleration time to 10 seconds and increased the torque percent to 20%, but it doesn't help. Please advise do I need a bigger VFD?

    We believe that this situation is due to the instantaneous overcurrent of the motor starting. Please follow the steps below to test again: Your motor wiring is three-phase 220V/440V, three-phase 230V/460V, please confirm whether your motor wiring is connected according to three-phase 220V or three-phase 230V? Please refer to the motor manual and double check the wiring of the motor.
    Please check what is the VFD starting current?
    Please check what is the starting current?
    Are you starting the compressor on no load or on load?

    Are you starting the compressor on no load or on load?
    What VFD settings do I need to change?
    Okay. Installed new gk3000, it ran the compressor and built up 150 lbs when pressure drop and try to restart got error E03 ?
    What settings do I need to change?

    ATO Responded
    When error E03 occurs, is it started with load or no load?
    Will it report error E03 if it runs without load?
    What is your starting current?
    The compressor has a set of start-stop loading logic.
    If the loading logic does not cooperate well with the inverter, it will fail.
    Please check the start-stop loading logic of the compressor.
    Hope my explanation is able to assist you.
    Look forward to your reply.
    5kW Aircon Application
    Here's my problem; I bought a 5 kW 220V aircon which is 3 phase but the power provision is single phase; Can I use VFD for converting single phase into 3 phase? Any recommendation or suggestion is highly appreciated. thanks

    Yes. 7.5 hp VFD meets your application.
    Do you provide reactors for 1-phase VFD?
    We are looking forward to using your 1-phase VFD for a wall pump application. The pump motor will be about 180 meters from the VFD and your VFD manual says to use line reactors if the motor is more than 100 meters away. Please advise if you provide reactors for 1-phase.
    VFD.

    Yes, we provide, and usually when the distance between the VFD and the motor is more than 100m, a reactor is required to be installed at the output.
    Recommend a suitable VFD
    We are looking for single phase input and output VSD for single phase fan 230VAC, 0.4kW. Could you please advice.
