MorganS:
I suggest you register at Sanyo Denki and download the manual for the driver.It looks like quite a capable driver with many functions. You probably only need a basic setup with the STEP and DIRECTION wires hooked up to your Arduino. Don't forget to connect the grounds.
Then any of the AccelStepper library examples should work.
Thank you for the reply, have the manual downloaded, and wired correctly for CW and CCW rotation it seems the step and direction wiring is catching me out at the moment
Thank you
