Cincinnatti arrow 750 kollmorgen acramatic 2100 retrofit was created by andrecorreia
Hello,
I'm from Portugal and i own two cincinnati arrow 750.
I register at this forum to find help in about the retrofiting i'm thinking to do.
My two machines are identical and from the same year.
They use kollmorgen bds4 drives with kollmorgen servomotors and acramatic 2100
One machine is mechanically perfect and all the eletronics are good but we are not being able to put it to work and my only support help is from usa ( i don't know anybody good at this machines in portugal) and we are reaching a point we waste so much money repairing the rt board, all the batteryes, hard drive etc, and the machine still not working.
And i love to work with acramatic!
The other machine have a burned spindle power supply but all the drives and control are good, and also have a lot more hours than the other one.
My idea is to retrofit the worst machine with linux cnc and to try repair the other one with original control.
What parts do you recommend to use to retrofit it maintaining the axis analog drives and motors?
I'm not any expert on this, the last 6 years i have my machine it was allways me who repairi them but i have my own limits, i know how to read eletrical diagrams and a little about c programing and also electrical conections and testing but i'm not a cnc service thecnician.
Thanks

Have you done a search for "Petefrom Tn "? He did a conversion to his Cincinnati Arrow . Never heard if he finished incorporating the tool changer but he did get the machine running , moved to Florida ( with his Arrow ) and is sometimes on the IRC net as Beachbum Pete..
Might be worth reading his conversion ,around 2013. Your biggest problem may be getting a computer board having low latency. My thought is download a " Linux CNC " live version an try various computer boards .
Keep us advised on how it is going. Photos are always great

3 Axis mills are ususally the easiest to retrofit. I have done a few.
mesa cards 7i92M and 7i77 if your drives are +-10 which I think they are. A 5v din rail power supply, 12 or 24vdc din rail power supply.
Some din rail terminals and some 12/24vdc relays and you should be all set.
An i5 computer works well.
It is much easier if you have the electrical schematic manuals for the machine.
Jon from Pico systems has some nice systems also, but I have never used them so I cannot comment on them.
Just my 2 cents,
Bob

Yes i read, but it's so many pages i get very confused.
So i need one pc. With low latency.
How do i test the latency?
I have one old pc.
This are the specs:
Motherboard Asus a8n-sli-premium
Ram: 4gb corsair extreme
2 ssd 200gb.
Processor: AMD Athlon x64 4.2 ghz
graphic card geforce gtx7800 xfx
would it be good for the cnc?

I have the schematic from both machines.
Is it possible to maintain all the wirings to the motors and limit switch?
