The Gecko 320 and 340 can deliver up to 20 A, but only at 80 V.
Above that voltage, you need the Rutex or other drive. But, running
at 80 V, all you lose is top speed. That may not be a problem in your
particular application. You have to calculate out the torque and
speed parameters of the particular motor, and combine it with the
mechanical setup (leadscrew pitch and drive ratio, if any) to figure
out whether you will get the required performance or not.
