You do have to set the resolver reader unit for the proper transformer ratio of the resolver, but that is about all there is to it. Tamagawa resolvers with wound rotors also work fine.
Now, some of the newer Tamagawa variable reluctance resolvers need a lot more drive current than my resolver converter can provide. Also, they usually have a very high number of poles, which makes it impossible to have a one-per-rev index pulse. Kirk may have meant that the thing reading the resolver needs to be set for the characteristics of the resolver, but it should be a standard practice to set that.
