TRIGGER PROFILE FOR A POWER TOOL

摘要

An improved method is provided for operating a power tool. The method includes receiving an input control variable from an input unit; determining a second derivative of the input control variable; selecting one of a plurality of control profiles based on the control input variable and the second derivative, each control profile correlating the control input variable of the input unit to a rotational speed at which to drive the output shaft; and driving the output shaft at a rotational speed in accordance with the selected control profile.
