Motor control system

A motor control system that communicatively connects, via a communication line, a controller and a plurality of motor control devices respectively controlling motors to each other, the controller generating a communication signal including each of operation commands for controlling each of the motors and transmitting the generated communication signal to each of the plurality of motor control devices in a predetermined communication cycle,

• wherein
• the plurality of motor control devices includes two motor control devices in a first group and a motor control device in a second group, and
• each of the motor control devices in the first group includes:
• a data transceiver that receives an operation command in the communication signal, the operation command being issued to the motor control device, and receives operation information in the communication signal, the operation information relating to the motor control device in the second group;
• a motor controller that generates, based on the operation command, a torque command signal for controlling the motor;
• a corrector that generates a torque correction signal based on the operation information and corrects the torque command signal using the torque correction signal;
• and
• a synchronous timing generator that generates a timing signal that matches pieces of process timing of the motor control devices in the first group with each other.
