Abstract
A system is provided that can automatically calibrate or define a home or initial position of a moveable component of an industrial machine. During the calibration procedure, an actuator may be operated in a low speed and/or low torque mode to drive the component until the component contacts a mechanical stop. This provides a hard-stop of the component's movement while the actuator attempts to further drive the component, which creates a stall condition of the actuator. A control system monitors that actuator's performance characteristics and is configured to identify an anomalous performance characteristic(s) value that corresponds to the actuator's stall condition as a triggering event. When the control system identifies the triggering event, it defines the component's position as a null point and determines a zero point to define an initial operational position of the component as a function of the null point.
