Need Help!- Reversing Stepper Drive

[FeldWill]

I'm testing a motor setup on SloSyn2000 and when I apply a 1khz frequency on step node and straight +5 volts on direction the motor turns in one direction. How do I simulate low signal for direction to get motor to turn in reverse.

Thank you
William

Apply 0V (gnd) to the direction pin.

Doesn't work. I even tried to get voltage down to 2V to mimic low signal on printer port. Is it posible to wire motor wrong so it can rotate one way but no the other.

My motor is "#23-205-DS8 285oz-in bipolar rating, 205oz-in unipolar rating. 3v, 3A, 200 S/R, 2.2mH, Size #23, Dual Shaft, 8 wire" from hobby CNC

Your problem should have nothing to do with the motor. It is a driver issue. If it goes one direction when you feed pulses in to the driver with the "direction" pin held high, then it should go the reverse direction when the "direction" pin is held low.

I am not sure what you mean when you say you even tried to get the voltage down to 2 volts. That is not the same as 0 volts or ground.

Make sure that you are in fact feeding the pulses in to the "step" pin and not the "dir" pin.
