I'm not 100% sure what you're wanting to achieve with the axis 90 but if you're planning on using them as a return pump, I would advise against it. These pumps are underwhelming for use as a return pump. I would consider them for supplying flow through media reactors but something that requires water to overcome head pressure, I would say axis isn't the right pump.
with that being said, the axis can be controlled via Fusion with the help of MXM. You'll have the basic function of controlling the pumps output based on time as well as what apex has to offer as a controller by setting feed modes and alike.
I use my axis 90 to circulate water in my salt mixing bin. It's a simple set up but here's how it looks in fusion.
As for the cor15, that's more of a traditional return pump. In fusion the programming is the same as axis, but it offers a widget that provides some novelty data.
And as you said, they can be connected via a 1link cable directly into an eb832 or a 1link module.
