What type of motors, and what are their specs? What condition are the servo amps in, and what type are they, what signals do they take? What type of position feedback does it have, and what are the specs there?

If you need more digital I/O, just plug in more boards. It has 4 axes of analog output per board, and 4 axes of encoder counter per board.
