    摘要： This disclosure discloses a motor driving system including a motor with an encoder and a motor driving device configured to control and drive the motor based on a motor control command. The motor driving device includes a first position detection unit configured to perform a magnetic pole position detection process for the motor to detect a position of the motor. When determining whether miswiring is present between the motor driving device and the motor, the motor driving device controls and drives the motor using a first detection result of the first position detection unit and determines miswiring of the motor based on a second detection result that is a position detection result of the motor by the encoder.
