Abstract:
To suppress increase of manufacturing costs while discriminating whether a motor is in a state in which a gear connected with a shaft of the motor does not rotate or in a state in which a signal line connected with a sensor for detecting engine speed of the gear is disconnected in a motor controller which controls an operation of the motor.SOLUTION: A motor controller 1 is constituted by comprising: a sensor Se1 which outputs a signal S1; a sensor Se2 which outputs a signal S2; and a detection unit 3 which detects an abnormality that a signal line SL1 is disconnected when the signal S1 to be acquired via the signal line SL1 is at a zero level, and detects an abnormality that a signal line SL2 is disconnected when the signal S2 to be acquired via the signal line SL2 is at the zero level.SELECTED DRAWING: Figure 1
