I'm not sure about the Mesa 7I30 board, but running servo power cables and the encoder cables long distances are generally not a problem if you use differential encoders. I installed some 1 KW servos with 60 foot power and encoder cables this past summer. I just quoted some Siemens servo drives and motors that have 120 foot cables.
