PURPOSE:To make an operation capable for selection from auto to manual running only with a handling of controller, by means of a selection made operable with an agreement detected between a speed of motor and a reference of speed given by the controller. CONSTITUTION:In a state with a motor 1 not in motion, a relay R1 does not work. With an automatic start push button AUP handled, a relay K makes a self holding, and the motor 1 will be made into an automatic operation by a signal of automatic speed reference device 3. If handled a controller 6 during automatic operation, a contact B of the controller 6 is closed with a relay contact BX-al closed. A generation of signal of a motor speed detector 4, at this time, causes a relay R2 to be working, and a speed of the motor 1, if thereafter when a diviation comes to be zero between a signal of the speed detector 4 and the reference signal of the controller 6, will be controlled with a follow-up made to the reference of the controller 6. |
