I use a complete pc-based motion-control which generates step / direction outputs. For controlling small dc-motors with attached encoders, I need a small interface, which counts the steps from the MoCo-System on one hand and the encoder steps from the motor on the other hand to generate an analogue or digital reference output. The motors need to be positioned precisely. The interface may be a stand-alone part or a complete unit together with a motor driver. Because I already have the pc hard- and software I do not want another part which have to be build into the computer. The interface should be not too complex (and too expensive). Does anyone have an idea what solution is possible?

it's posible. But my model have error in time.
With my program impose the reference in position and the time who want to arrive at this refernce.

Describe the error.
My time to arrive is time you want to arrive plus 0.7secundes.
After this 0.7 secondes you have the position wanted.

This value is generated with the matlab simulink.
If you arre interested send me a replay.
Thanks for your time to read this mail.
