Yes. Is there a pulse output module available? The Yaskawa servo (Sigma2?) can close its own position loop, and provide a discrete 'in position' output.
Or, if my memory serves of overpriced, underperforming Logix5000, isn't there a motion control card (analog out, feedback encoder)
I suppose it boils down to what you want the servo to do - point ot point, camming, registration.
BTW, I've no idea what an auger is
