An actuator device having a motor driven cam, a follower coupled to an output member and driven by the cam, and a controller for controlling operation of the motor. The cam has a first cam surface, a second cam surface and a lift portion between the first and second cam surfaces. The controller is configured to identify a predetermined point on the lift portion as the follower is moved relative to the cam along the lift portion toward the second cam surface. The controller identifies the predetermined point based on a rate of change in the position of the output member along an output member axis as a function of the rotational position of the cam about a cam axis. The controller controls operation of the motor based on the predetermined point to position the follower on the second cam surface.
