Have you tried using the following example program for the sinusoidal output?

There isn't a known, easy way to use the onboard PID algorithms of the 7344 board with an external wave generator, as you do not have access to input the wave data to the algorithm.
You can use the DAQ board with the MID drive, you will have to create a custom cable to connect the proper signals however. A PID loop in LabVIEW will be software timed - if this is an issue for you, you may want to look into using the LabVIEW PID toolkit with LabVIEW Real-Time, which guarantees deterministic
behavior.
