The hardware and procedures described here constitute a technique for measuring the failure modes of step motors. A DC motor and optical encoder are mechanically connected to a system being driven by the step motor. Control logic senses when the step motor turns on and gates signals from the optical encoder into an up/down counter in the control logic.
