することを目的としている。 This invention was developed in view of the drawbacks of the conventional control device, in which when the motor is overloaded and the operation is stopped, the load current of the motor naturally becomes zero, and at this time the load ammeter does not operate. Not yet. Furthermore, when the electric motor is operating normally, the display device that displays abnormal conditions is not operating.
Therefore, the above-mentioned load ammeter and display device were designed with the focus on the fact that when one of them is operating, the other is not, and displays the load current when the motor is operating normally. It is an object of the present invention to provide a control device that is inexpensive and compact by providing a display device that has a function of displaying an abnormal location when an abnormality occurs.

During normal operation, the number of the light emitting diodes lit up corresponds to the magnitude of the load current flowing through the motor, and among the light emitting diodes that light up according to the magnitude of the load current during abnormality, only the light emitting diode corresponding to the content of the abnormality lights up. Since the structure is equipped with a display device that lights up, the multiple light emitting diodes used as level meters for the load current can also be used as light emitting diodes to display the abnormal location in the event of an abnormality. In a control device for an electric motor, the device can be made inexpensive, and the circuit space of the printed circuit board can be reduced, so that the device can be miniaturized.
