2M2280N High Voltage Stepper Driver

Parallel will give you more speed / mechanical power, but will also run a lot hotter.
My suggestion is to try it in series and if it works for you leave it there.
If you find you need more speed, connect it in parallel.
Dont forget to set the correct currents.
If it is the FL86STH156 or SY85STH156 it is 3A in series and 6A in parallel.

Parallel or series? Would it make any noticeable difference to the top speed or just generate unnecessary heat?

Hi Gary

It goes fine and dandy but it's running the motors hotter than I feel comfortable with. If I put a drop of suds on the motor, it boils.

I can't reduce the currrent because 3.18A is as low as it goes.

I can switch to paralell and, effectively, run less current. When you say, "A lot hotter" do you mean the motor or the driver?

You can try in in parallel and monitor the temps.
With this driver the motors will run hot, but they shoud be ok.
