Maintenance support system, numerical controller, and control method of maintenance support system

A numerical controller for controlling drive of an operating mechanism of an industrial machine, the numerical controller comprising:

• a first information generating circuitry to extract data related to an operation anomaly from among data related to a state of operation of the operating mechanism when the operation anomaly is found in the operating mechanism, and to generate first information including the data extracted;
• and
• a transceiver to be able to communicate with a support device that generates second information to be proposed to the numerical controller for maintenance of the industrial machine,
• the operating mechanism is a mechanism that causes an object of movement to move in a direction of each of a plurality of axes, and
• the first information generating circuitry extracts the data related to the operation anomaly for a portion extracted from a command path d for a direction selected on the basis of a direction of movement corresponding to the portion extracted among the directions of the plurality of axes, the command path being a path along which a command position as a target of movement changes.

A control method of a maintenance support system comprising a numerical controller to control drive of an operating mechanism of an industrial machine and a support device to be able to communicate with the numerical controller, the maintenance support system supporting maintenance of the industrial machine, and the control method comprising:
