Hi Nick.

Can you list the parts you have and want to hook up to the ub1?

UB1 eliminates some stuff like the need for multi psu's and make things a little more straight forward.

So when you list parts people can start helping you.



Grtz Bert.

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.

Damnit! Dont have the ub1 so I can't help you. Hate running into trouble so I hope you can get this party started!

Hi Robert!
With all the helpful guys at this forum I am sure that something good is going to come up!

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.

Finish the power supply, thanks everyone for the help.

Clive,my mistake,psu delivers lower voltage than this i mention.
Thanks for watching my back.
