A motor control system includes a motor control apparatus, a motor, an environment state detector, and an operation state monitor. The motor control apparatus is configured to control feeding of driving power based on a control command. The motor is drivable by the driving power. The environment state detector is configured to detect environment state data of at least one of the motor control apparatus and the motor. The operation state monitor is configured to output, based on the environment state data, an operation margin of an operation state value of the at least one of the motor control apparatus and the motor relative to an operation rated value of the at least one of the motor control apparatus and the motor.

Motor control system, motor control apparatus, method for controlling motor, and state estimator

The motor driving system includes a driving state amount detector configured to detect a driving state amount, a motor control part configured to perform a power supply control, a higher control part capable of outputting a higher control command to the motor control part, and a safety requesting part that inputs a safety request signal to the motor control part. The motor control part includes a motor control circuit part that performs the power supply control, a mode selecting and executing part configured to select and execute either a first safety function mode or a second safety function mode, and a comparing and monitoring processing part that compares the driving state amount and a predetermined operation monitoring pattern, when the safety request signal is inputted.
