How to Send PWM signals to a Motor Controller through DAQ?

So i recently started with labview... and part of my first project on it requires that i use a motor controller to control a fuel pump.

 

During my searching for a compatible fuel pump and motor controller, i have found the Crytron 30A 5-30V DC Motor Driver, and the Aeromotive 11101 fuel pump.

 

However, while trying to work on how i plan to make connections and control these, i have run into the problem that he motor controller runs off of PWM signals, and the DAQ i have (9474) doesn't seem to output any voltage other than digital output. Im not sure if this makes sense, but i think it may be the problem i am running into.

fuel pump: https://www.aeromotiveinc.com/product/a1000-fuel-pump/

 

the motor controller specs are listed, but as for those of the fuel pump:

"Aeromotive A1000 Electric Fuel Pump
This is the pump that started it all. Durable, reliable, good looking, and it supports high horsepower. Perfect for the daily driver that doesn't run like a daily driver. For up to 1500hp carbureted. ORB -10AN inlet and outlet ports.

Hi ShamtejRana711,

 

For future reference, questions about using DAQ devices would be better suited to the Multifunction DAQ forums that can be found here.

 

Using the DAQmx drivers in LabVIEW we should be able to generate a PWM signal to be able to communicate with his motor controller. I have included an article that discusses how this can be done and provides some examples. 

 

Pulse Width Modulation (PWM) Using NI-DAQmx and LabVIEW: http://www.ni.com/tutorial/2991/en/  

 

Because it sounds like you are just getting started with LabVIEW, I have included an extra helpful article about getting started with DAQmx below as well. 

 

Learn 10 Functions in NI-DAQmx and Handle 80 Percent of Your Data Acquisition Applications: http://www.ni.com/product-documentation/2835/en/ 

 

Using both of these resources together should put you in a great position getting started with your project. 

 

Thanks,
