1. A drive method for a production machine adapted to drive an actuator of the production machine by use of a power drive source, the method comprising the steps of:
- driving the actuator by use of the power drive source, while switching drive output of the power drive source among a plurality of different drive outputs;
detecting values of at least a physical quantity regarding an operation state of the actuator and a physical quantity regarding energy consumption corresponding to the operation state;
selecting one of the drive outputs on the basis of the detected values and in accordance with a predetermined selection method; and
driving the actuator with the selected drive output; and
wherein the power drive source is a hydraulic drive source, and the actuator is a hydraulic actuator driven by the hydraulic drive source,wherein the step of detecting values of the physical quantities includes performing detection processing in response to selection of a detection mode,wherein the detection mode is selected by use of an output selection screen displayed on a display, andwherein at least an electricity saving ratio with respect to electricity consumption at the time of the maximum drive output is displayed on the output selection screen.

Abstract
An actuator is driven by use of a power drive source, while drive output of the power drive source is switched among a plurality of different drive outputs. Values of a physical quantity regarding an operation state of the actuator and a physical quantity regarding energy consumption corresponding to the operation state are detected. One of the drive outputs is selected on the basis of the detected values and in accordance with a predetermined selection method, and the actuator is driven with the selected drive output.
