(NEWBIE) How to use an (Fanuc) AC Spindle servo motor for an DIY CNC router

You are right, have found that. But the reason i thought to go for the Easy servo is also because i found some thread here in forum where someone had exactly that problem with the 0-10V / -10 ~ 10V.. Somehow i cant find that in my history any more, but he couldnt give them any more back and he wasnt very happy with that purchase. Have a bit fear that i will have some big problems later...

Ah, yes, I vaguely remember that now too. The manual clearly says that Bipolar Operation is possible.

Have a look at servostar 6 series, they look quite usefull with plenty of options and can be found for under 400 euro in Germany. I do not belive they can be used for induction motors, so please do check that. Pdf aplenty.

They are AC servo drives with plenty of options. If i decide to get them, i will use them for everything, meaning axis, spindle, rotary or whatever i might be building. I did not have time to study them thoroughly, but they do have everything i might need.

If on a budget, you could look at stmbl

Andy, i am very interested in that because, i have read something about "parts cost 70€", but i have never build boards by my own self and it sounds like you have to do it and buy every small piece of that board to create it..

Indeed, and when some parts come in reels of 100 or 4000 the price to build one is much higher than €70

I have seen stbl quite some time ago, but building one (or several) is not an option, from to much time invested to meesy wiring to way to expencive. I build everything for fun and testing and learning, but the case in point does not pay off.
I think i saw them assembled and tested for 149 somewhere, add a power supply, rectifier, capacitors, connectors and the price goes beyond a used servostar, ending up with a device that has one method of communication and ........you get the point.
I am using some PWM drives that cost 23 euro for 2 motors (11.5 for one, but two on same board), with Linuxcnc for smal servo motors and they do work, they can not replace a fully fledged servo drive.
Servostar 6 series takes 3X208 up to 3X480V so i can just plug them to 3 phase outlet at 3X380V and be done with it. Adjustable output voltage is also a very nice feature when mixing and matching to motors.
Bevins, on ebay.de is one seler that has 3 606 for 299 each and another has 1 603 i think for the same price. The rest is way north on price. Two night ago when i checked they where still there.
