Beschreibung
Zusammenfassung:	The invention provides a multiaxial motor control system configured to control motors for a plurality of shafts included in a multiaxial machine, and including a plurality of motor control devices and a controller. The controller has network connection with the motor control devices, and is configured to transmit a command signal to the motor control devices. Each of the motor control devices includes a communication controller, a rotation controller, and a drive unit, and is configured to drive a motor for a corresponding one of the shafts. The communication controller is configured to transmit and receive signals including the command signal, and determine whether or not the command signal is received normally. The rotation controller is configured to generate a torque command for operation of the corresponding one of the motors. The drive unit is configured to generate a drive voltage for electrification to drive the corresponding one of the motors in accordance with the torque command. When at least one of the motor control devices detects failure in reception, the at least one of the motor control devices outputs a torque command for braking torque to stop the corresponding one of the motors.
