Hello Guys

I have a Wasino CNC lathe that is rated at 2.2Kva and I only have single phase 220 in my shop. I need to know what size VFD would work with this lathe. Thanks in advance for your input.

You would need at least a 3Kw VFD, and capable of using a Braking Resistor, larger the VFD for a lathe the better, usually go by the spindle motor Hp, you want the VFD to be at least 2Hp larger than your lathe motor

Thank you for the information, what is a good manufacturer

I have a Huanyang 10HP VFD and it keeps kicking the vfd off, I have a rotary phase converter but was told that if I hook it up to the CNC it would blow the computer in it and this VFD keeps kicking out

You can only use a VFD to power the Spindle Motor, it can not be used for any other electronics or to supply power to any other part of the machine, a VFD can only supply Power to a 3 PH AC Motor
