AC Servo's

HI guys!

I have a knee mill BP (clone)10 X 50 table that I would like to
convert to CNC.
The decision has been made : the controler (software ) will be Mach 3
( or Mach 4). I have three AC servos geared (100 to 1), 0.55 Kw, 3000
RPM, 230 V that I would like to use.
My question is how I link the software to the AC Servo's? Seen that
all the details are for DC STEPPERS not AC SERVO'S I couldn't find
anything in that respect.

I appreciate any inputs !

Best regards,

Marius
