Abstract
In an embodiment, a method of controlling a step motor system includes operating the step motor system in a normal mode. In the normal mode, the step motor is advanced upon receipt of a step pulse. If a failure event is detected, the step motor is operated in a failure mode. In the failure mode, a failure counter is incremented upon receipt of the step pulse, and the step motor is not advanced.
