ABSTRACT:
A test unit is electrically coupled between a motion controller and each of first and second redundant brakes. The test unit is responsive to the motion controller for automatically selecting one of the brakes to be tested. A microcontroller receives a signal from the motion controller that identifies one of the redundant brakes for activation, or deactivation, by an associated microcontroller output. The microcontroller outputs may be coupled respectively to activation terminals of respective brake switches connected in parallel to a brake activation voltage.
