Andy,
I am guessing on this, but I don't think the jumper keeps the brake on when the controller is not powered. If that was the case, you wouldn't be able to push the robot with the wheels on the floor. Also, as I remember, IFI started including a varistor across the output. This was something we previously had to add to the output terminals. The device is designed to eat up spikes from brush noise and back drive so I think it limits the voltage to 40 or 50 volts. I am going to have to look back at the specs on the devices we had to add in the past.
