Help with NI 9501 C-Series Stepper Motor Drive

[TurboM]

Hi NI community

I need to drive and control a stepper motor, with time and money being obvious constraints.I have a cRIO 9073 and LabVIEW 2011 Academic License at my disposal. Could someone please advise me on the following options:

1) NI 9501 C-series stepper drive. (good value for money but not to sure about examples, support and scan engine compatibilty)

or

2) NI 9512 stepper controller and P70530 drive. (most expensive option, yet it seems to be the most easily implemented)

or

3) Arduino board, generic controller (L297) and motor drive (L298N). (cheapest option, but then again not sure about implementation)

I need urgent advice as my project deadline is due at the end of this year...

Any advice will be greatly appreciated

Regards

TurboM

Hello TurboM

Thank you very much for getting in touch with us!  Here is my take on your options.

1)  The NI 9501 is not scan engine compatible.

2)  This option would garner you the greatest support amoung our service centre and the NI community.

3)  If you are interested in using the Arduino board, we actually have a toolkit available for it in LabVIEW.  You can learn more about it at the following link:

Thank you very much for choosing National Instruments.  I may be able to assist you more if you describe your application in detail.  I am happy to help and am committed to your success.

hey I want to enable the drive of my c series module 9051..how can i do that..please help me its urgent..because I can detect it in my project explorer but there is no physical indication that its connected no leds etc i mean..however I have connected external supply as well as motor with my c series module

There's example code already included in LabVIEW that you can use to control a stepper motor's velocity or displacement with the 9501. There's an invoke node used to enable the drive, that could be what you're missing. I've got similar hardware and it took a couple of tries with the example code to get our motors spinning, which required me to make a couple of tweaks in the VIs.

What version of LabVIEW are you using? I could forward you the code I've been working on so far so that you can try it out with your own hardware.
