You've got Hood here, Terry Can't think of someone with more experience with AB drives around here.

They are AC.

Serious beasts indeed at 220Amps... Sounds more like a TIG welding machine spec than a servo's  Continuous current was probably around 70Amps and hence the power in access of 6kW... WOW! Probably were high RPM and low torque.

I see. I have a 1990 Cincinnati Falcon lathe awaiting retrofit. Mechanically and cosmetically it's almost new despite its age. Problem with it is that the motors have resolvers, but keeping the original Kollmorgen drives is something I want to avoid as I heard they tend to fail. On the other hand getting rid of the motor is a shame as they are in an excellent condition.

Hood,

Doesn't really look so good, but I am sure it's going to be a great machine after your magic touch

May I ask why you decided not to use the original motors? My guess is they have resolver feedback? Then why not use the original drives? Or their condition isn't good? Or you afraid of future failures with them?

Hi Terry,

Open Ultra Master Help file and look for "Setting Ultra Master Advanced Mode". This will tell you how to access the advanced features of Ultra Master. Custom motor creating is one of them.

Regarding the sensors, the Chiron has them on the cylinders, there is a cylinder for each tool, each having a prox sensor top and bottom and then two more cylinders either side that lower and raise the basket.  It looks at first a very complex set up but  when you study it is actually quite simple and seems reliable as the only thing my friend has had to do in the 15 or so years he has had it is replace pipes as the originals started splitting.

Heres a vid of the style on the Chiron.

That's one cool tool changer. Definitely the fastest I have seen.

If the basket can't rotate then setup is not an easy task, trying to reach the tools on the rear.

Thanks, Hood. That sounds really good! Got two Cincinnati machines (a mill and a lathe) awaiting retrofit and I am quite convinced now that the CS Lab controller is the way to go. Although the delayed pullout in threading would a be a problem on the lathe. Hope it gets sorted by the time I get to it.

Yes. Just remove that part.
