    Can 1 phase to 3 phase VFD be Used with a Laser Cleaning Machine?

    I purchased a GK3000-CS0150G 15KW (20 hp) 1 phase 220VAC to 3 phase 380VAC VFD.
    My three phase 380VAC equipment machine has a Neutral Wire.
    Where do I wire this Neutral wire to the three phase 380VAC side in your 15KW VFD?

    This Neutral Wire cannot be connected to the VFD, but can be connected to the ground. Please refer to the attached picture.
    Note that the 15kw 220VAC single phase to 380VAC three phase VFD you purchased can only be used to connect three-phase 380V motors, and cannot be used to provide power to your equipment, otherwise the VFD will fail.

    If this VFD will not work for my purpose can you suggest what will work?
    My machine is a laser cleaning machine, so it has a laser power supply, a cooling pump, pc logic control boards, and an LCD display.
    It is the typical voltage for 380VAC three phase.
    I have 220vac single phase.
    I was informed this VFD would work. If this will not work can you explain why? And also suggest what will work.

    This is because VFDs are usually only used for motor load. If you use it as a power source to supply power to machines and equipment, it may be unstable and cause malfunctions.
    For your application, we recommend using a Single Phase to 3 Phase Converter, which can convert your single phase 220V to 380V. Please see the converter spec on: https://www.ato.com/phase-converter
    Please also let us know the total power, voltage, maximum starting current and other data like these of the laser cleaning machine you are using, so we can recommend an appropriate model.
    Of course, you can also use this VFD for testing now, but we do not guarantee that the VFD will run your machine properly. Anyway, you can try testing first.
