Re: Resetting Encoder
We're not 100% certain of this, but our experience with using an indexed encoder with the Jaguar closed-loop control has been pretty bad. We're very likely going to disconnect the index pin tomorrow. The basic issue here is that it doesn't seem that a scheme where the encoder count is reset by the index works very well, the PID control seems to get really confused by the wrapping that happens when you go from 0 to full-count (for one revolution) and then back to zero -- this proably holds in either direction of rotation.

Has anyone gotten this to work? I think if you were to use some type of switch connected to the index pin you might be OK, as long as you either aren't using closed-loop control, or only reset the index once (not once per
revolution). What I'm wondering is if anyone has gotten closed-loop control with a real index encoder to work.
