Hi Ulf

That's what I'm trying to figure out. At present state I do not really 
know how much EMC might save me, probably 20k EUR. Depending on how 
difficult the conversion would be this could be worth it or not.

I'll certainly lose a lot of nice features of the professional 
controllers, but mostly features that I don't need. But it would 
certainly take a few weeks to do the conversion.

That's a good point, I have to make sure it's possible to link the 
digital servo drives to EMC. I didn't think of this problem yet, because 
I never worked with these new digital servo controllers.

Do you have any details on that?

Would be an option indeed, I'll try to figure out how much that would be.

I thought about that, but having the machine under the manufacturer 
warranty is a good thing. Of course I will lose warranty as soon as 
starting the conversion, but I could wait for a few month and use the 
new machine in its original 3+2 set-up at first.

See you
Flo
