摘要： A motor control system includes first processing circuitry that controls a motor. An upper-level communication path connects an upper-level communication port of the first processing circuitry to second processing circuitry that sends an instruction to the first processing circuitry via the upper-level communication path. A lower-level communication path connects a lower-level communication port of the first processing circuitry to a plurality of devices connected in series to each other. The devices include rotational angle detection circuitry and output circuitry. The rotational angle detection circuitry detects a rotation angle of the motor. The output circuitry outputs associated information that is associated with the motor and is different from the rotational angle or that is associated with an industrial device associated with the motor. The first processing circuitry performs a predetermined processing based on the rotational angle and the associated information, and sends a result of the predetermined processing to the second processing circuitry.
