Will this VFD and Electric Motor Work With ACORN (and each other)

[ChrisMe]

I'm going to start building a CNC mini lathe and no off the shelf motor will work and I'm not good with the electrical stuff so I was wondering if anyone can tell me if this VFD and motor are comparable with each other and Centroid Acorn. I need the motor to reverse (I have the lathe set up so parts will not unscrew themselves).

The VFD is the Schneider Altivar 12 ATV12H018M2-

This is the single phase small motor-

Will these work? I'm trying not to complicate things to much but if these will work can I add a braking resistor?

Thank for the help.

VFDs need a three phase motor not a single phase motor. You need to read up on VFDs

Thank you for the reply. It is appreciated. I don't have access to a 3 phase power supply I only have a standard wall socket. If I have a motor that plugs into a standard wall socked how do I control the speed of it?

Thanks.

The VFD converts single phase incoming power into 3-phase power to control the motor. The ability to change motor speeds is dependent on three phases. You will need to select a VFD that is rated for single phase input. The 3-phase motor voltage and the single phase supply voltage must be the same.

You cannot control the speed of a single phase AC motor.

I've had the pleasure and stress of setting up a few VFDs before on other controllers.
Firstly you must read the manual (to grasp how easy or difficult this is) and watch a few Youtube videos--there will be people who've done what you're wishing to accomplish.

(This guy might have some basic ideas and answers here on what to consider or look for. It may be a waste of time but does show a 3 phase motor and a vfd along with programming... To help you get an idea of what may be going. )

When you find the right setup you're stuck setting it up, navigating the menu, and programming it so it accepts 0-10v analog signal to control the frequency...

Realistically I think you only need 0-10V analog setup but you might want an enable to be setup so the drive can't turn on without a second signal. You may wish to program the VFD to only do a specific speed range according to motor or machine requirements.

You're going to want to consider a shut off switch, a fuse, and breaker (whatever the MFG suggests)--I've never used such measures but I'm told it's a wise idea, and I purposely have my VFD where a fire won't kill me or destroy the shop.
