Stepper motor control using NI MYDAQ

Well, it depends on the drive connected to the stepper. The myDAQ cannot control a stepper directly. There has to be some components (drive) in between. The drive could has an Ethernet, serial, PROFIBUS, etc., interface. It could have a couple of TTL inputs (e.g., go forward, go reverse). The stepper motor itself doesn't matter but the drive controlling the stepper does.

You've asked the equivalent of 'how do I build a bridge?'. There's a lot more information and work that goes into that question than we can really go into here.

 

Your local suppliers for motors and drives can help you with selecting components appropriate for the task. The individual supplier will route you toward their product line. I normally don't get involved with motor selection, but you'll need information on physical envelope, worst case pressures, the type of valve you're using, etc, to calculate how much horsepower you need (what is the metric equivalent for motors?) and what speed you need to run at. The more you've clarified what you need the system to do the better (well, any) supplier can help you.
