One big gotcha we ran in to on a Mazak machining center was the
velocity servo amps need a tachometer feedback, and this was
provided by the CNC control. You may well have the same
situation on that machine. Your choices, if you want to retain
the Fanuc servo amps, are to install tachometers on the motors,
or to get a device that converts encoder signals to a velocity
signal.
