Need Help!- I'm confused

[FUBAR62172]

Hi all, I'm in the process of starting a small hobby shop in my garage. I have a Anilam 3300mk control miller and I'm trying to get it power. I have bought a Hitachi AC Inverter from driveswarehouse.com( http://www.driveswarehouse.com/advan...32141&x=11&y=8 ). Has anybody here set one of these up that could possibly give me some pointers?Thanks

Will you just be driving the spindle motor with the Hitachi unit? What part number is the Hitachi unit? (the link just went to a search page) What power do you have available?

I have model #SJ200-022NFU, it's only purpose is to drive the motor and I have 220 power availiable. I thought I could just wire it up and go but I guess I was mistaken. Thanks for any help

I am assuming you have the instruction manual http://www.driveswarehouse.com/docum...chi/SJ200M.pdf
and have looked it over. You will probably want the EMI filter at the power input to the drive to keep electrical noise from feeding back down the input power line. There will be some programing of the drive required to get it to operate with your motor. The example diagram on page 4-5 of the manual shows the gereral connection scheme. For remote on/off (run forward only), the simplest connection to the terminals PCS and 1-6 would be a switch from the PCS terminal to terminal 1. A relay contact from your machine controler could be used in place of the switch ( the original spindle motor contactor for instance ). You should be able to program fairly rapid acceleration and deceleration rates for your application. If you plan on controlling the spindle speed from the controller, things become a bit more complicated. Not knowing the specific output available from your controller precludes me from advising further at this point.

Do you think I should hire a electrician or something, or do you think a machinist with basic electrical knowledge could figure it out??

Most VFD's will run out of the box, there are a few minimum parameters that should be set, e.g. 2 or 4 pole motor, voltage etc, you have not mentioned how far you have got with it?
If you can operate a computer, you should be able to make headway with a VFD, although obviously you have to be capable of hooking up the basic wiring requirements, which are not that complicated.

What everybody has failed to tell you so far is that a VFD only powers an electric motor.

To control a complete machine you need a ROTARY PHASE CONVERTER

The downside is while the ROTARY PHASE CONVERTER is running and not running the machine you are destroying the planet wasting electricity and wasting money.

Post #3 mentions he is controlling the motor ONLY.

Opps missed that

The controls on the machine run on 110v only the motor is 3 phase.I have the machine tied into the VFD just like it was pluged in.however when I tried to start the machine by my machine controls nothing happened. I'm guessing there's more complicated wiring involved to make it right but I'm not sure

It sounds like you are trying to integrate it into the controller analogue output for spindle control?
First get it going and set it up by placing a pot across the speed input terminals, the manual will show how to do this, once you have it set up manually then you can progress to hooking it up to the controller.

Al, not sut what you mean by "pot". also do I just need to hook up the FWD and RVS relays to the inverter? thanks
