ABSTRACT:
A method is provided for controlling hydraulic flow to a hydraulic actuator in fluid communication with a pump. The method includes generating a signal representative of a speed of the pump and selecting a relationship from a plurality of relationships between valve commands and an operator input. The selection is based upon the speed signal. A valve is modulated to control the hydraulic flow to the hydraulic actuator based on the selected relationship and the operator input.
