Motor drive system, motor drive device, multi-axis motor drive system, and multi-axis motor drive device

摘要

An object of the present invention is to determine the presence or absence of miswiring while reliably preventing unintended motor operation. A plurality of drive units 303 respectively associated with and connected to a plurality of motors 100, a general control unit 302 that controls the entire multi-axis motor drive device 300, and each axis control unit 304 are provided. In the multi-axis motor drive system 1 including the shaft motor drive device 300 and the plurality of motors 100, the overall control unit 302 and each shaft control unit 304 perform the magnetic pole position detection process for the motor 100 connected thereto, respectively. Each of the plurality of motors 100 includes an encoder 102 that detects the position of the motor 100 through mechanical connection. The overall control unit 302 and each of the plurality of motors 100 have a magnetic pole position detection unit 306 that detects the position of the motor 100. The axis control unit 304 controls the driving of the plurality of motors 100 using the magnetic pole position θ detected by the magnetic pole position detection unit 306. The encoder 102 is determined based on the motor position detection.
