BDC-Comm "Gate Fault"

[DesignFlaw06]

We decided to use CAN this year, using the RS-232 to CAN bridge inside the Black Jaguar. Had it working just fine earlier in the season. Of course it gets close to ship date, and now we can't get it working.

Using BDC-Comm, we get a red rectangle that says GATE FAULT in the upper right corner on two of the jags (we've got a total of six, and the other four run perfectly). We've tried each Jaguar individually, different computers, new cables, different configurations, etc and can't get anything to work consistently.

On Jag #2, we get the gate fault only when trying to drive the motor with a positive voltage value, it'll go the opposite way all day, but as soon as we try to go the other direction, it stops and we get a gate fault. Jag #5 gives the gate fault error as soon as we choose that Jag from the drop down list, although the error will occasionally timeout long enough for the wheel to spin for a second or two.

Any help would be greatly appreciated. Thanks!
