Re: PWM

If you do a direct replacement of Open 4 Motor for Open 2 Motor where the PWM constants have already been defined, then the PWMs can end up wired to the wrong spots (and there may not be enough of them, or too many).
This is also true if you use the speed controller pull-down selector to change from a PWM to a CAN type of control. You need to remove the old PWM constants and create->constant new inputs.

When you replace a vi with another, it's safest to also delete any input constants and recreate them, so they end up correctly wired to their new input spots.
