Abstract
A motor control system includes a main control unit, a power supply unit, and a driving unit. The main control unit obtains sampling data of a motor and a power supply signal from the driving unit, generates a motor control signal according to the sampling data, and outputs a safety enable signal when determining that motor drive is abnormal according to the sampling data or when determining that power supply to the driving unit is abnormal according to the power supply signal. The power supply unit supplies power to the main control unit, monitors a state of the main control unit, and outputs a safety cut-off signal when the power supply unit or the main control unit is abnormal. The driving unit drives the motor according to the motor control signal, and switches to a safe path when receiving any one of the safety enable or safety cut-off signal.
