PROBLEM TO BE SOLVED: To reduce power consumption as much as possible, while taking account of a state where a current is fed continuously in order to keep the stop position, even in the stop state of each servo motor concerned in a prescribed work for mounting an electronic component on a substrate.SOLUTION: A controller 20 determines whether or not the mounting of an electronic component on a printed board P can be started, and if a determination is made that the mounting cannot be started, determines whether or not Y1 motor 11A, Y2 motor 11B, Y3 motor 11C, Y4 motor 11D, X1 motor 12A, X2 motor 12B as the servo motor, are in the servo state. If a determination is made that the servo motors are in the servo state, the controller 20 controls not to feed a current to each motor, by stopping the position loop control for keeping the command position of each of the motors as the servo motor. |
