Re: [CAD_CAM_EDM_DRO] Encoder question

Ok, thanks i purchased the motors because of price and availability hoping i
could use the encoders. they draw 17 to 40 ma so should be ok on a Gecko
drive. the motors are 3 phase brushless and i havent seen but a few pricey
control drives for them with step and drive inputs.
1.5 amp motors that i wouldnt add a 350 dollar drive card for each one, i'd
get 700 ozin motors used and a gecko and be far ahead in the power
department. thanks, brian f.
