In case you want to know which COMs are connected to the motors you can run a COM analysis.
Select from the Tools menu COM analyzer
A window will show all the available motors, select the one you are interested of or all (clicking on Select all). FlyControl will run the analysis.
You can add a new motor in Management which is below the Motors node.
If you have already some motors configured in FlyControl you should get this screen:
Click on New and add all the information about the new motor. Then select Save.
Description (where you can write whatever you want)
Type of motor (linear, Z, rotary)
NB If you have no motors configured you just have to add the same information and save.
