Hi Sam,
Looks like the Stepnet motor driver is what we call a "communication-based" driver, it can accept commands coming from your PC/PLC via RS-232. Here's how I would get started:
1. Use the Copley Controls CME 2.0, and see if you can control the motor from this tool. This would be a good foundational check to see if all of the hardware is working properly. You don't want to go down the rabbit hole of LabVIEW, without knowing that the hardware is OK.
2. Refer to the Copley Controls documentation to see how to send commands to the motor driver via the RS-232 port. A good keyword to search for in the manuals is "ASCII". Anytime ASCII comes in documentation, it means you can send a string command to the motor driver. You'll probably need at least 2-3 basic commands, such as "move motor" and "stop motor". (I won't dive into the commands for Copley, as it's different for each vendor.)
3. Use the example finder in LabVIEW and find a VI called "Serial Read and Write.vi". For RS-232, make sure your baud rate settings are correct, and try to send a command from LabVIEW from the PC RS-232 port to the motor driver RS-232. If it works, great! Try out different commands and see if they all work as expected.
If everything is successful, you should have proved that you can send commands to the Copley driver from LabVIEW. From here, you can continue to develop your LabVIEW application, which is another field of discussion.
If the above doesn't work, the Stepnet driver also accepts I/O-based commands in the form of digital pulses. In this case, you'll need a motion controller or a PLC to produce these pulses. Check this out for a LabVEW-compatible motion controller: https://geco-lv.com/geco-motion.html
Hope this helps.
