The STG-II card is okay for your configuration. You just have to connect the
analog outputs of the STG-II card to your servo drivers. They will normally
take a current in the range 0 .. 10 V to set the desired speed. Also, you
will have to connect your encoders to the encoder inputs of the STG-II card.
You may want to tune your servo drivers (no integral value, maximum
proportional value) before you tune your system using the axis controller
(EMC).

Please correct me, if I am telling you crap and that's not your
configuration.
