Good Day To Everyone

I attended seminar for yaskawa F7 drives in the past. I enjoyed it and would like to keep practicing at home. Since Ive been a machinist for the greater part of my life I have very little electrical experience. I am seeking help in building a trainer. What I have is a
CIMR F7U40P7 480v 2.1A drive
.25hp motor

Any help is very much appreciated.

Well, first of all, how can you provide 480V (and supposedly 3-phase) power at home?

Hi Sergei Troizky
The trainers that we used were run off 120vac. I was thinking of a step up transformer. But I am not sure of the wiring for the 3 phase.

Here is what I use to run my mill at my house but it isn't 480.

Most small VFDs can be run on single phase input power. If that is the case with the drive you have, then stepping up your shop's 115 or 230 volt single phase to 480 will be successful. I've done it with a small Fuji drive.

Most small VFDs can be run on single phase input power...

Typically, only 120V or 240V VFD are intended or may be configured for single-phase power.
The subject drive manual does not mention single-phase power possibility even for 240V units.
Sorry, Don, but you've stolen a wrong one (joking ).
