PROBLEM TO BE SOLVED: To provide a drive circuit built-in motor capable of communicating from the outside with a built-in microcomputer via a VSP terminal and an FG terminal which are conventional control input/output terminals.SOLUTION: The drive circuit built-in motor includes: VSP signal input means 31; FG signal output means 32; communication input means 33 for serial communication; communication output means 34; a motor drive power input terminal 13; a first terminal 11 and a second terminal 12 that are interface terminals with an external unit; and detection means of the motor drive power voltage. When the motor drive voltage is higher than a reference voltage, the first terminal inputs a VSP signal and the second terminal outputs an FG signal. When the motor drive power voltage is lower than the reference voltage, the first terminal inputs the communication and the second terminal outputs the communication. |
