Controlling motor driver using Labview and SC2345?

[JimboMcJambo]

Hello,

I am trying to control a motor driver using labview and I am lost as to what the process would be. I want to use a motor driver like this one https://www.sparkfun.com/products/9457 and I am not sure if I can directly interface it with my equipment. I am using a NI USB-6251 connected to a SC2345. Which pins would I use to control the pins on the driver? Also how would I go about creating a program to do this? I want to be able to start the motor and control the speed of it using PWM. Any help would be greatly appreciated.

Thank you,

Hi!

Have you worked with LabVIEW before? You need LabVIEW along with the NI DAQmx driver to control the USB DAQ-6251. the NI SC2345 will only route the DAQ outputs. You basically only need digital signals to control the drive and you have enough in your DAQ. However, you will need a separate power supply for the motor(s). For the PWM signals that control the velocity of the motor, I would recommend using a DAQmx Counter Output task so the PWM is generated hardware-timed. You could also use Digital Output task and generate the PWM software-timed, but it is going to be less stable. For the rest of the signals that the drive requires you can use Digital Output tasks.

Regards!
