What is this???

I know this isn't really CNC related, but the knowledge on this site is unparalleled.

I scored a dead Aqua Massage table. Some of the parts were already removed and tossed, but what remains is a gold mine of electronics.

The link has pictures of all the various parts and pieces, but I'm mostly wondering about is the Unidrive, Model SP2201. Is there any way to test it? Is there any value in it?

Looks like an Emerson product. Also looks like there is documentation available.

Here is the product brochure.

Looks like you hit the electrical lottery there.
