Zusammenfassung:PROBLEM TO BE SOLVED: To detect the abnormal rotation of a turret, and also, to present an operating state to an operator. SOLUTION: When a power source is turned on, a stepping motor 20 is driven so as to rotate the turret. When a toggle changeover switch 11 is operated by a positioning pin 10, the rotation of the stepping motor 20 is stopped, then, the initial position of the turret is decided. Thus, the open-loop rotation of the turret is controlled. In the case the turret does not reach the initial position after a lapse of prescribed time, the warning is given to the operator.
