  • Patent number: 11728711
    Abstract: A numeric value control unit outputs a connection diagnostic signal to a target position switching unit to place the three-phase motor in a position at an angle that causes no torque generation upon application of a diagnostic current to the three-phase motor, and thereafter, outputs a connection diagnostic signal to a current instruction switching unit to apply a diagnostic current. Then, in order to apply a diagnostic current to the other two phases, the three-phase motor is placed in a position at an angle that causes no torque generation upon second application of a diagnostic current, and a diagnostic current is thereafter applied. When a diagnostic current is applied twice and in the case where no defect in connection is detected in either application, it is determined that connection is normal. Meanwhile, in the case where connection is detected once or twice, it is determined that connection is defective.
