Abstract
A control system for orienting a swing axis of a work machine is disclosed. The work machine includes a swing frame and a frame structure, and the control system includes an operator interface configured to receive operator inputs, wherein the operator inputs represent a desired orientation of the swing axis of the swing frame. The control system also includes a sensor assembly configured to determine an actual orientation of the swing axis of the swing frame and a controller configured to compare the desired orientation to the actual orientation of the swing axis to determine a swing angle. The controller is adapted to output the swing angle. The swing axis may be adjusted by adjusting the work machine frame or by adjusting a frame assembly independent of the work machine frame.
