Best Drive for Fanuc AC servos

[Ross77]

I had a dig around today and found the kolmorgen Goldline XT servo motors on another project and they are nema 34. If they work then they would get me started and maybe replace later.

That said Granite devices sell motors so If the Fanucs did pack up.

Are the ones from Ali express good quality?

I just had a search and the Goldline XT are shown as discontinued.

The Granite drives do look quite versatile, so using another motor shouldn't be too much of a problem.

DaveK used the Chinese drives on his Bridgeport conversion, and I'm pretty sure Jazz has used them.

I'm going to use Allen Bradley drives for my triac with fanuc reds
I've bought a few for around £100
I've been testing them with various motors up to 3kw off single phase and step/ direction. They are very versatile when you work out how to set them up!
I know fanuc use strange comutation but these can commutate without halls etc.
Probably the most versatile drives I've ever tested.
