Abstract
To make it possible to determine the cause of load variation in a motor drive control system, a motor drive control apparatus has a motor; a mechanical load driven by the motor; a control unit configured to control the motor; a detection unit configured to detect drive data including input data and output data in a system including the motor and the mechanical load; a status monitoring model calculation unit configured to calculate a status monitoring model using the drive data, the status monitoring model being formed by a plurality of parameters; and a determination unit configured to determine a cause of variation in a characteristic of the system including the motor and the mechanical load based on a change in the parameters forming the status monitoring model.
