Abstract
A system and method for correcting position of a pusher member after power loss to a motor controlling the pusher includes a pusher transport having at least one pusher member mounted to belt and a controller for controlling the pusher transport. A motor is coupled to the belt for controlling the movement of the pusher transport. The motor is driven by a driver coupled to the controller. An encoder is coupled to a shaft of the motor and operatively coupled to the controller, wherein the controller is programmed for using encoder counts representing pusher member position at power loss and at power restored to determine whether the pusher member is past or before an expected position at power loss. The controller is also programmed for determining the distance and direction the pusher member must move to be at the expected position, the controller causing the driver to drive the motor at a specific motor profile to move the pusher member to the expected position.
