SV500 servo drives

[eman5oh]

I am considering buying 3 sv 500's for my router project. I picked up 3 Electro craft E543 with 1024 line encoders. Any one have this combo, if so how well does it work for you? I am also interested if you have a different set up with these drivers. Are they easy to tune? Would you recomend them? The price is great if they work well or would I be better off with holding out and buying gecko's. Thanks

Thanks

Hi eman5oh,
the driver cards look ok but are only rated to 30 volts, from the information I have gathered about the E543 motors (I have some and intend using them on my project) they are rated at 60 volts which means the SV 500 cards will work but you wont be able to acheive maximum torque or rpm from your motors. For me the jury is still out on which cards to use but I am leaning toward the Rutex r990h.
Cheers

I tested the servos in the lab and at 30 volts I should be able to get 200 IPM on my setup and they feel to have way more torqe than the steppers that they will replace. The sv500 would be maxxed out in this aplication but would provide way better preformace than the steppers i have now. I can buy the sv500 now but will have to wait a few months to buy geckos or rutex cards.

hi, i'm about to buy some sv500's to put up a cheap CNC router, anyone tried those drivers already?
my servo's will probably be 12V 3 or 4amps, do you know a cheaper servo driver than the sv500 ($65 each when buying 3 of em)?
regards, Max.
