Abstract
An abnormality determination system includes motor control circuitry that controls a motor of a motor-driven machine based on a motor control command, and compares operation data of the motor obtained in controlling the motor with reference data stored in a storage to determine whether the motor driven machine has an operation abnormality, upper-level control circuitry that transmits the motor control command to the motor control circuitry, and data transceiver circuitry that transmits and receives the reference data and the operation data to and from the motor control circuitry.
