I purchased a used machine that has a 4th axis drive installed but, came without the rotary. I would like to install a rotary and would like to know if it's possible that a SMW 4th axis with a 22pin and 17pin connector will work? Is there any way to see in the parameters or ladder for the type of previous rotary installed? The previous owner does not know since it was purchased used through a machine dealer.

You could buy the Fanuc manuals for the specific servo drive the machine has. That will tell you exactly what servos are compatible with it. Then I'd shop for a rotary of similar vintage based on what servo motor it has. Once I had the rotary the real work will begin to get the two to play nice together.

If you need a 4 axis machine it's best to buy one or you can do what most people do and use the 4th to index. This is easy to do with any machine and indexer.
