Abstract
Embodiments provide a multiaxial motor control system for controlling motors for a plurality of shafts included in a multiaxial machine, and including a plurality of motor control devices and a controller. The controller is connected with the motor control devices, and transmits a command signal to the motor control devices. Each motor control device includes a communication controller, a rotation controller, and a drive unit, and drives a motor of a corresponding shaft. The communication controller transmits and receives signals including the command signal, and determine whether the command signal is received normally. The rotation controller generates a torque command to operate the corresponding motor. The drive unit generates a drive voltage for electrification to drive the corresponding motor in accordance with the torque command. When a motor control device detects failure in reception, the motor control device outputs a torque command for braking torque to stop the corresponding motor.
