Controlling 2 stepper motors using LabVIEW

$

Motors - 2 NI NEMA 23 stepper motors (780073-01 and 780077-01)

Motor Power Drive - NI MID-7604 

Motion Controller - NI PCI-7334

 

To begin with I checked that the driver can deliver the necessary power to the motors. The 780073 requires .40 amp/phase and the 780077 requires .67 amps/phase. The driver I selected supplies 1.4 amps so the motors should work with the driver. I will be using LabVIEW for the first time this upcoming week so I'm trying to do some studying on the program this weekend. I have seen some people use Boolean structures to control when specific phases turn on. I found this post on this forum to be very helpful, but I don't have LabVIEW on my laptop right now. Can anyone please explain to me the steps (specifically what each icon means) that this person is taking and whether or not this is something that I can use?

Thank you,
