Latest and Greatest Labview Driver to Control Velmex Vxm Stepper motor

[CRivett]

Or does anyone know what generally causes these types of hangups in labview?? So that I can try and modify the Velmex driver?

thanks again

Hi CRivett,

NI provides drivers for two Velmex devices, but I don't think that either of these are the device you're currently using. If you need newer drivers for your device, you can try contacting Velmex to see if they've developed newer drivers since this thread was originally started.

Driver communication is complicated, and could lead to many different difficulties working with your machine or other applications. Unfortunately I can't narrow down any specifics on what could be causing this driver to hang up from LabVIEW.

I suggest you try contacting Velmex for more information, and try doing basic VISA communication with your device to see if you run into similar issues. You could also create a new forum thread, since newer posts tend  to get more responses.

I hope this helps!

Had the same problem with the controller freezing up. I used the VxmDriverLV8.vi to send "K" immediate command and then the "res" immediate command if the controller didn't respond with an "^" within a certain amount of time.
