I recently came across a wiring schematic of a ub1 board that included clearpath servos on the forum. Got a copy of the schematic, but not the attendant explanation. Now I can't find it, searches turn up nothing. Of specific interest is that the HLFD signal from the clearpath was wired into the system. A couple of BOB makers have suggested leaving this connection out on their products. I want to know if this is the "channel" that sends an alarm when there's an issue at the servo and, if so, how do I implement this into my system (I'll be using a MB3/ESS system). Any assistance is greatly appreciated.
