connecting stepper motor to the module 9512

[Jimmy_Page]

Hello,

I must do project in LabVIEW.

I use the compactRIO with module 9512 (Stepper Drive Interface Module with Encoder Feedback). I built a small program of this tutorial http://www.ni.com/white-paper/9666/en#toc10. Now I need connect stepper motor to the module and I would like to run my VI.

I want to connect small stepper motor (which once was in the 3.5-inch floppy drive - this is bipolar motor with four pins) with module 9512. I don't know which pins DSUB or MDR I must link with my inputs stepper motor. "In Getting started with NI 951x.pdf" written: "Connect the Step and Direction outputs to the stepper drive." and "Connect the Drive Enable output to the stepper drive."

Which outputs I should connect with my stepper motor?

Thank you in advance.

Hello Jimmy,

The 9512 is a CONTROL module which generates step/direction pulses that need to be interpreted by another piece of hardware, the stepper DRIVE (hence the name, stepper drive interface module).

A drive (such as our P7000) will take these step/direction pulses and convert them into the proper format for the stepper itself.

To run my motor I need additionally NI 9512 to P7000 connectivity bundle and stepper drives for example P70530 (something else)?

It's not possible to run motor without this elements?

[Edwin_Wise]

That is correct, these elements or their equivalent.  It is necessary to convert the control signals from the 9512 into motor drive signals.

The P7000 getting started gives an overview of all this:
