Abstract
A method for controllably moving a work implement attached to a work machine. The method includes the steps of inputting a velocity command, determining a plurality of desired cylinder positions as a function of the desired velocity command, and comparing the desired cylinder positions to allowable cylinder positions. The allowable cylinder positions are a function of a combination of the plurality of desired cylinder positions. The method also includes the steps of moving the work implement to a desired work implement position as a function of the desired cylinder positions, and stopping the movement of the work implement in response to at least one desired cylinder position being at a limit defined by a corresponding at least one allowable cylinder position.
