摘要: A rotation control system may be provided for a material handling machine. The rotation control system may include a boom and a work tool attached to the boom. A swing motor may be capable of swinging the boom and the work tool. A work tool motor may be capable of rotating the work tool relative to the boom. An input device may generate a first signal indicative of a desired swinging of the boom and a second signal indicative of a desired rotation of the work tool. A controller may be in communication with the input device, the swing motor, and the work tool motor. The controller may be capable of actuating the work tool motor based only on the second signal during a first mode of operation and may be capable of actuating the work tool motor based on swinging of the boom during a second mode of operation.
