controling four bipolar stepper motors using one DAQ

[polarmess]

hi all

      l've just started using  labview an i am looking to contorl Four bipolar motor  for a spine robot though four stepper motor driver using a NI USB-6211  DAQ each motor will be independent so i am wondering can this this be done with one Daq since there is only two counter outputs on the digtal and the same on the analog.the speed of the motor does not matter as they will be push and pull.

Hi polarmess,

Welcome to the NI Discussion Forums and LabVIEW. The USB-6211 has (among other functions) 4 digital outputs and 2 counters. If the digital outputs are not sufficient for your application (e.g. not quick enough) and you also want to control each of the 4 motors individually, then then USB-6211 would not be suitable for this application.

The NI sales team are always available to provide advise on hardware for specific applications, and I encourage you to call in to your local NI branch to discuss what the most appropriate hardware would be to control your robot. Our contact details are available via the contact link on ni.com.
