Claims

[Scope of utility model registration request]

(1) In a motor control device that includes a timed start circuit that delays the start of the motor for a certain period of time after detection of a motor start signal, and an indicator light that displays the operating status of the motor, when the timed start circuit is activated, an indicator light is provided. The device is equipped with a timed start operation display output circuit that outputs a timed start operation display signal that controls the lighting state of the indicator light so that it can be distinguished from the lighted state of the indicator light in the steady operating state, and the timed start operation display output circuit outputs a timed start operation display signal that controls the lighting state of the indicator light so that it can be distinguished from the lighted state of the indicator light in the steady operating state. A control device for an electric motor, characterized in that the two are identified by a common indicator light.

(2) While the timed start circuit is operating, the timed start display signal output to the indicator light is an intermittent signal at fixed time intervals, the indicator light flashes, and furthermore, the timed start operation is completed and steady operation resumes. The electric motor control device according to item (1), characterized in that the control device for an electric motor according to item (1) is characterized in that the indicator light is continuously lit by outputting a continuous signal.

(3) Utility model registration The control device according to claim (1) is characterized in that a timer circuit, a timer display circuit, and a switching control circuit of the timer are incorporated into the controller and provided with an IC. A control device for an electric motor.
