Motor drive control device, motor drive control system, fan system, and motor drive control method

A motor drive control device, comprising:

• a motor drive circuit configured to drive a target motor based on a drive control signal and
• a drive control circuit configured to generate the drive control signal for controlling driving of the drive-target motor and
• to communicate with an environment outside of the drive-target motor, the drive control circuit comprising a processor;
• and
• the processor configured to generate measurement data including a measured value of a physical quantity related to operation of the drive-target motor;
• and
• the processor configured to set the physical quantity related to the operation of the drive-target motor as a monitoring parameter, and monitor an operation state of the drive-target motor based on measurement data of the monitoring parameter and a reference value of the monitoring parameter,
• wherein the processor is configured to determine whether the drive-target motor is in an abnormal state based on a comparison result between a deviation of the measured value from the reference value of the monitoring parameter in the drive-target motor and a deviation of the measured value from the reference value of the monitoring parameter in another motor acquired by communicating with the outside environment, and
• the processor is configured to acquire information about the deviation of the measured value from the reference value of the monitoring parameter in another motor from a host device or a drive control device of the another motor.
