1. A motor drive control device comprising:
a drive control signal generation unit configured to generate a drive control signal for controlling driving of a motor;
a motor drive circuit configured to drive the motor based on the drive control signal;
a communication unit configured to communicate with a host device transmitting a command ordering acquisition of the training data;
a measurement data generation unit configured to generate measurement data relating to operation of the motor;
a training data generation unit configured to start attaching predetermined identification information indicating an operation state of the motor to the measurement data and generating training data when the communication unit receives the command ordering acquisition of the training data from the host device;
a machine learning unit configured to generate a learned model for determining the operation state of the motor by performing machine learning using the training data; and
a monitor control unit configured to monitor the operation state of the motor using the learned model.
