Motor using Encoder as Limit Switch?

[randalcr]

So our team wants to use an encoder as a limit switch. Meaning we want to stop a motor from going so far forward, and prevent from going too far backward while still being able to move anywhere in between. The issue is that none of our programmers have enough experience with using encoders nor the know how to make them function as limit switches. Any suggestions on how to do this?

Thanks.
