SMC EMY2 Stepper Motor Control

[Spiderman156]

Hi,

I am trying to set up a stepper motor to run with labview 8.2. I am pretty sure that the code I have written should work so I am trying to figure out if I have wired everything correctly, I hope this is the right place for this. I have added the description and manual for the SMC EMY2 stepper motor (page 22 is where I am looking mainly for the wiring, I am using the 5-point Stoppable Type) and manuals for the two NI DAQs I am using, NI9474 for the control singals to the motor and NI9423 for receiving signals from the motor. I am using an external power supply with these that is set to 24V. I have the NI 9474 in slot 5 of the cDAQ-9172 and the NI 9423 in slot 6. I have attached to the power supply cable wires wires as described in the EMY2 manual to the power supply and the motor runs fine when using the attached controller, then I have attached the I/O wires as follows:

Brown - Vsup of the NI 9474

Blue - Com of the NI 9474

Pink - line 0 of the NI 9423

Orange - line 1 of the NI 9423

Yellow - line 2 of the NI 9423

Red - line 3 of the NI 9423

Green - line 4 of the NI 9423

Purple - line 3 of the NI 9474

Gray - line 7 of the NI 9474

Black - not attached

White - line 2 of the NI 9474

I can get the NI 9474 to output a signal but the stepper motor does not seem to react at all. I had a colleague recommend that I connect the - terminal of the power supply to the ground terminal, is that a good idea. If anyone can think of something to help that would be great and if you need more information just ask and I'll try to get it.

Thanks.
