My web page has a screen shot of an earlier version of the EMC screen,
it still looks much like this : http://pico-systems.com/EMC.html

There are two ways to do this. The simple method has the encoders ONLY
feeding back to the servo drive, not the computer. The fancier method
requires a card of some sort added to the computer to count encoder
pulses. There is a stepper version (I'm not absolutely sure it is on the
BDI
CDROM) that accepts encoder feedback. With this version, then you DO
get what you are asking for.

You can also run a full servo system, where the encoders feed back ONLY
to the computer, and the servo amps only try to match motor velocity
to the velocity commanded by the computer. There, the computer can
always display the actual position, both with motors on or off.
