If you're talking about when the robot is disabled, I'm pretty sure the PWM pins are left floating. We noticed a side effect of this last year when we ran some servo wires close to our RS232 for the camera, and when the robot was disabled the RS232 would generate enough noise on the (floating) PWM line to cause our camera servos to twitch. Actually, now that I think about it, if those PWM wires had been connected to a Victor, it could have been a dangerous situation. When the robot was enabled, the PWM output was being driven such that noise was not an issue.
