Re: PIDs out of control

We noticed this past weekend that every so often, one of our drive motors will just start spinning at a high speed, even though we had a 0 hard-wired into the Set Motor Output VI. We still haven't figured out the cause yet. The speed controller (a Talon from last year) was green, which signifies that it thinks it is getting a valid speed command. We didn't find any short circuits of any type. We just stopped the code and restarted it, and the problem went away. This makes us a bit nervous. I'm wondering if it could be related.
