Yes Bert what you say it's true, UB1 needs only 24volts which converts it to 5 volt , with some restrictions,has on board 3 relays , from those you can control a sequence , powering up power relays etc.and other features.

My problem is that it is more complicated than the one and only 5$ bob I have ever install, at my previews cnc and also much more expensive, the last one makes me more nervous to experiment! I must be a 100% sure before power it up!

My parts are:
2x AM882H
2X AM882
1x78Volts PSU 7Amps
2x12 volt psu 330watt
HY VFD with 2.2kw water cooled spindle
water pump...etc.
I hope I did n't forget a major component , if i remember something I will edit my post.

Thanks,Nick.

1x78Volts PSU 7Amps

Do you really mean 78v with AM882 drivers !!

[Nickhofen]

Hi Clive.
If I recall right ,PSU is rated somewhere between 74 to 78volts,is the power too high?
Also I forgot to mention the 4x 4NM motors.

Alao I forgot to mention the 4x 4NM motors.

That is a little high for AM882 drive 68v is more realistic

Any home switches?

Do you want to control spindle speed by 0-10v?

Estop?

Air valves?

cooling pumps?

Right now I have the Estop ,NPN proximity switches and water pump.
I will add all the rest ,everything I can add and also a potentiometer for spindle speed control.

I can add and also a potentiometer for spindle speed control.

I posted this some time ago. #1 http://www.mycncuk.com/threads/7388-...se-Spindle-VFD

Try to make a diagram with the help of UB1 manual....

[Nickhofen]

This is what I come up untill now, no water pump or stepper motors yet added.
HY VFD is going to be connected according the second schematic.

Can you guys check the diagram to see if you find any issues, I add also the manual of UB1.
Also please suggest where to put fuses and relays.

Thanks,Nick.

One thing I see is that you seem to have fuses in the -ve line from the 72v PS that is NOT good practise and are not necessary. Also 5A may be a bit low
