I can't find that motor on the japan servo website. What are your plans to connect it to? Have you selected a driver? If you are wanting to use a Gecko drive then you better hope that your servo is a "DC Brush" type servo. The motor needs only two connections + and -. The encoder will need to have 4 connections and be compatable with the drive. The connections are +5vdc, -, A, and B.

Are you sure you have a servo motor and not a stepper motor?
