Abstract
A motor control system, in some embodiments, comprises: a voltage divider circuit having an output node, a voltage on said output node representing a desired motor rotation direction; control logic configured to receive an indication of said voltage; and a motor controller coupled to the control logic, wherein, if said indication of the voltage on the output node falls outside of a predetermined range, the control logic is configured to issue a motor stop signal to the motor controller indicating that at least one resistor of the voltage divider circuit is defective or is missing from the voltage divider circuit.
