Abstract
A sensor device, such as a torque sensor, of a motor control device or an electric power steering apparatus includes a sensor section that detects a quantity of state of a detection subject and outputs a detection signal corresponding to the detected quantity of state. When receiving a specific trigger transmitted from an external device, the sensor section outputs an abnormality diagnosis signal, which is configured by a predetermined waveform and used for determining whether there is an output abnormality of the sensor section, and then outputs the detection signal.
