running brushless servos with emc

I am the very lucky owner of a 3axis setup that has brushless servos.
Draw back is that control system was via delta-tau cards.
Amplifiers are copely 10v+- signals. I need help/advice on what I
need to add so I can use EMC for control.
I have two of these machines and one is part way thru a conversion
to steppers. Seems a waste to do this to the second one.
The motor/encoder/amplifier/power supply connections are all intact
omly my inexperience is keeping me from having a very cool servo
20x20x12 machine.
I have investigated the delta-tau setup[thanks for the advice on
that] I quickly came to the conclusion that I have neither the skill
or money to use them.

thanks
