Hello

Can help wiring single phase motor 220vac to VFD? thank you

Your picture is not showing. Unless you have a special VFD designed for a single phase motor you can't connect a single phase motor to a VFD.

Also 1ph induction motors have a bad record when used on an appropriate VFD made for 1ph, they have been known to drop out of run at low rpm especially with a load.
This is one reason why the 3ph is much more popular.

i saw this link but not clear wiring 2 cable motor to UVW.

My milling motor 1000w 3phase failed need to replace two choice by single phase motor or use stepper motor 86 12NM,

i have tested this step motor by this control Pulse / PWM generator for stepper motor drivers - Hobby Components running well +DM860H
what you think?

That motor is a simple shaded pole motor, you can also control them with a Triac controller, any other 1ph motor you would be lucky to get away with it with a VFD.

There are some VFD drives that can run a single Phase motor, here is ( 1 ) I had on file, I have not looked at it, but it has single phase in and out

The gamble is with 1ph motors on a VFD is to whether or how your 1ph motor will perform, even at all, this the VFD manuf. cannot guarantee, with a 3ph motor there is seldom the same concern.

If the stepper motor has enough speed for your milling, then yes, that will turn the motor. You might be able to see about 1200 RPM out of the motor, but probably less, but not much torque at that speed.
