  • Publication number: 20160241170
    Abstract: A motor control device includes DC voltage circuitry which obtains a DC voltage, an inverter which converts the DC voltage obtained by the DC voltage circuitry into an AC voltage that is output to a motor, a voltage detector which detects the DC voltage obtained by the DC voltage circuitry, and regenerative controller circuitry which controls actuation of the regenerative circuit based on the DC voltage detected by the voltage detector. The regenerative controller circuitry waits until a predetermined waiting time period has elapsed and thereafter actuates a regenerative circuit in the DC voltage circuitry, independently of actuation control by second regenerative controller circuitry in a second motor control device that also obtains the DC voltage, after the voltage detector detects that the DC voltage exceeds a predetermined threshold voltage.

  • Patent number: 9389597
    Abstract: This disclosure discloses a motor control device including a main circuit, a voltage detector, and a controller. The controller includes a position controller and a speed controller, The position controller generates a speed command. The speed controller generates a torque command and controls a inverter based on the torque command. Further, the controller includes a torque limiter, and a speed matching instruction part. The torque limiter starts torque limiting by the torque command to a predetermined torque or less and cancels the torque limiting. The speed matching instruction part matches the speed command with a first position command speed after the cancellation of the torque limiting. The holding part calculates and holds an accumulated position deviation.

  • Publication number: 20160149523
    Abstract: A motor controller to control a motor includes a position controller, a speed controller, a first integrator, and a second integrator. The position controller is configured to generate a speed command based on a position error between a position command and a motor position. The speed controller is configured to generate a torque command to be input to the motor based on a speed error between the speed command and a motor speed. The first integrator is configured to calculate an integral value of the position error to be added to the position error. The second integrator is configured to calculate an integral value of the speed error to be added to the speed error.

  • Publication number: 20160065099
    Abstract: 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.
