Servo Signal Transfer

Hey guys,I'm trying to retrofit a brake press and I need some advice on how to connect three servo motors. I want to use a MesaBoard, so I'm wondering what type of electronic connection and interface would be better.I've included some pics of the servo motors and drives I'm working with, so you can get a better idea of what type of stuff I'm dealing with. If anyone has any diagrams or schematics for the drives and encoders, that would be  helpful. I tried to find some online, but no luck so far.Any tips on how to connect all these components and get the functionality? Thanks for your help!

infranor is still live .... better to ask they datasheet .... seems a very old drive where PID is reuled from trimmer .... seems first '80 technology .... take one for your personal electronic museum ..... after these you would use that motors and drive? .... think some Lcnc friend here sell a more reliable and precise servodrive with little investment (500€/drive?) ... After these think you need change reducer too .... so non sense using old motor and drive. You work is more and more expansive than new servodrive+new reducer+professionl pc for Lcnc. Total amount can be 3000€ .... regards
