MOTOR CONTROL SYSTEM

Document Type and Number:

WIPO Patent Application WO/2017/195578

Kind Code:

A1

Abstract:

In this motor control system, a plurality of motor control devices which control a motor are connected to a controller via communication lines. The controller generates a communication signal which includes an operation command and transmits the communication signal to each of the motor control devices in a predetermined communication cycle. The plurality of motor control devices include two motor control devices of a first group and a motor control device of a second group. The motor control devices of the first group each include a data transmission and reception unit, a motor control unit, a correction unit, and a synchronous timing generation unit. The data transmission and reception unit receives the operation command directed thereto and receives operation information about the motor control device of the second group. The motor control unit generates a torque command signal for controlling the motor on the basis of the operation command. The correction unit generates a torque correction signal on the basis of the operation information and corrects the torque command signal. The synchronous timing generation unit generates a timing signal for synchronizing process timings between the motor control units of the first group.
