  • Patent number: 11226607
    Abstract: An abnormality determination system includes motor control circuitry that controls a motor of a motor-driven machine based on a motor control command, and compares operation data of the motor obtained in controlling the motor with reference data stored in a storage to determine whether the motor driven machine has an operation abnormality, upper-level control circuitry that transmits the motor control command to the motor control circuitry, and data transceiver circuitry that transmits and receives the reference data and the operation data to and from the motor control circuitry.
    Type: Grant
    Filed: April 9, 2018
    Date of Patent: January 18, 2022
    Assignee: KABUSHIKI KAISHA YASKAWA DENKI
    Inventors: Takaaki Shogaki, Takeshi Nagata, Tadashi Okubo, Naoki Mizuno, Atsunobu Sakata
  • Patent number: 10771000
    Abstract: A motor control system includes a motor, a motor control apparatus that drives the motor and includes a first communication port and a second communication port, an upper-level control apparatus connected to the first communication port via a first communication path, an interface connected to the second communication port via a second communication path, and one or more detectors that detect information for controlling the motor and are connected to or including the interface. The motor control apparatus includes processing circuitry that obtains the information detected by the detector and exchanged between the upper-level control apparatus and the interface, and controls the motor based on the obtained information.

  • Patent number: 10664263
    Abstract: A software management system includes a control system connected to a first network and including at least one of control circuitry and a sensor, each controllable by updating first control software in the respective at least one of the control circuitry and sensor, a software distribution device including first circuitry that stores second control software and transmits the second software through a second network, and a software update device including second circuitry that, while the software device is connected to the second network, receives the second software from the distribution device and stores the second software, and while the update device is connected to the first network, transmits the second software to the respective at least one of the control circuitry and sensor to cause the respective at least one of the control circuitry and sensor to update the first software using the second software.
