Abstract: An electric actuator motor drives an actuator leg between inner and outer limits of an actuator stroke relative to an actuator base. A controller detects when the actuator leg is at one of the inner and outer stroke limits by monitoring and comparing actuator motor power draw to known actuator motor power draw values associated with the operation of an electric actuator when its leg has reached an actuator leg stroke limit. A position sensor senses changes in the position of a monitored actuator component and provides corresponding signals to the controller. The controller calculates the position of the monitored actuator component relative to the position that the monitored actuator component was in when the actuator leg was in a predetermined home position. The controller recognizes and records the concurrent position of the monitored actuator component as indicating that the actuator leg is in the home position whenever the leg reaches a stroke limit.
