I've read through most of the posts here and one of them talks about not reading encoders.  I'm not getting feedback, and I'm not sure why.

I have a DMC-2143 card.  I can see the encoders are working with a TPA command in GalilTools, and if I spin the motor, I can see the Units/min register report the speed in Mach.  But, if Mach reads the encoders to report the speed, why doesn't it display position in the position DRO?  Is there a special type of DRO box for this?
