I have the need to build a test setup which I can control using an analog +/-10VDC signal for forward and reverse motion. A stepper motor could be a good way to do this if I could build/buy a driver the send the pulses proportional to the input signal. I've seen one that can use a 0-5V input, but if I could locate one that uses +/-10V by default, that would be nice. I'm OK with building electronic kits or following simple plans, so if there is a DIY solution, I would be OK trying that too.
The task is for a test apparatus, so accuracy and precision are not really a huge concern. I just like how my CNC machine has nice slow motion rotational control and thought a stepper would be adequate for the design. I'm open to other suggestions (servo etc) but I don't have a lot of experience with other options. As far as stepper size goes, a low power (50oz-in should be plenty) motor is all I think I should need.
I'll be glad to supply more information if needed. I'm not really sure how to tackle this yet, so I might be leaving out a critical piece of information or two.
Thanks for any help that you can provide.
