I want to use the arduino to control a stepper driver, trouble is in the data sheet it is references different wiring for different types of motion controller (PNP,NPN, or differential).
I can't find any reference to the arduino being one of these types, can I still use it? If so which one is it? I don't particularly want to have to buy another motion controller as I have an arduino lying around.
Attached screenshot of stepper driver data sheet.

PUL-, DIR-, EN- to ground,
PUL+, DIR+ to Arduino pins, EN+ to 5V (if you want it permanently enabled).
The sheet shows how the inputs just go to opto couplers (LED + current limiting
resistor), you are just driving those LEDs.

Thanks for your reply.
That would correspond to the PNP diagram then? For the NPN, PUL+ and DIR+ go to 5V and the PUL- and DIR- go to the Arduino pins.
In effect yes. You could wire it the other way and then have your output pins
active low. Its easier to think of with the negative inputs at ground I reckon.
