Thanks for your continued support Andy it's much appreciated
I haven't bought any motors yet, I was going to buy the matching motor for the drive from RS, here's a link if you feel like checking it out (
uk.rs-online.com/web/p/servo-motors/7701485/
). They are quite expensive at ~ £2,300 for 3x axis (I'll add the 4th at a later date) but it was the higher performance that attracted me to them. The Servo motors use 20 bit encoders 1,280,000 cpr and the drives have dynamic auto tuning which alters the servo tuning in real time based on the machining conditions, I thought this would be useful for when I have real heavy parts on the table.
I've searched for servos quite a bit and the best alternative that I could find were the DMM Servos (
www.dmm-tech.com/index.html
) they're ~£800 cheaper for a similar system but at a lower performance. If you know of any good sources for servos I'd love to hear them!
I've never seen the General Mechatronics stuff before, they can run on CAN bus and utilise the linear encoder feedback too! Their systems look real neat. I'll do some digging, do you know if they have a good reputation?
I did look into ±10V analogue velocity control but I was under the impression digital commands offer greater performance?
Cheers,
