That forum discussion pretty much solves all my doubts. It seems the driver uses tacho generation to close the speed loop within itself, and the only signals I need to replace are the analog voltage for the velocity command and some of the ready and fault signals to make it work. Also the pin information is a great help to start testing. I'm not sure about one thing in the pictures of my drivers and it's the fact that there's a connection between the two of them, I'm going to see if I can find out something on my PDFs but I'm not sure about what that might be for. I'm planning on use the resolvers as you suggested since they work really great and also everything is already mounted so practically I don't have to touch anything of the mechanical units. I hope I can do some testing soon because replacing the original control will give me a lot of new functionalities.
