Title:
MULTIAXIAL MOTOR CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/159472
Kind Code:
A1
Abstract:
This multiaxial motor control system is for controlling motors by a multi-shaft machine having a plurality of shafts, and is provided with a plurality of motor control devices and a controller. The controller is connected to the plurality of motor control devices through a network, and transmits a command signal to each of the motor control devices. The motor control devices are each provided with a communication control unit, a rotation control unit, and a drive unit, and drive the respective motors of the plurality of shafts. The communication unit transmits and receives signals including a command signal, and also determines whether or not the command signal has been received correctly. The rotation control unit generates torque commands that cause the motors to operate. The drive unit generates, on the basis of the torque commands, drive voltages for activating and driving the motors. In the case when one or more motor control devices have detected abnormality in reception, at least one of the motor control devices outputs a torque command for generating braking torque to halt the motors.
