A method for diagnosing faults in an industrial machine. The method comprises identifying a first state associated with the industrial machine, identifying at least one second state associated with the industrial machine based on the first state, for each identified second state, determining a state time associated with the second state, determining a fault indicator condition responsive to determining, based on the at least one second state and the respective state times, that the industrial machine spent a time period different to a predetermined time period in at least one of the at least one second states, generating, responsive to determining the fault indication, diagnostic information comprising an indication of the one of the at least one second state, and outputting the diagnostic information in a user interface of the industrial machine.

A servomotor control device in a processing machine that processes an object to be processed on a press supporting unit driven by a servomotor includes: a pressure detection unit configured to detect an actual pressure applied on the object to be processed; a pressure command generation unit configured to generate a pressure command that commands a pressure that the object to be processed preferably receives; a pressure control unit configured to generate a speed command for the servomotor on the basis of the pressure command generated by the pressure command generation unit and the actual pressure detected by the pressure detection unit; and a speed command limiting unit configured to limit the speed command generated by the pressure control unit using a predetermined value.

A production facility is provided with: an AGV for transporting a plurality of fuselage panels of multiple types having different shapes in a mixed state on a previously determined transport path; a plurality of A/Rs for riveting the fuselage panels; work areas set so as to correspond to the respective A/Rs in which the A/Rs move to rivet the fuselage panels; and a buffer area, set beforehand in the transport path adjacent to the work area, to which the A/R corresponding to the adjacent work area moves so as to rivet the fuselage panel. When there is no fuselage panel to be riveted in the work area adjacent to the buffer area and the fuselage panel to be riveted is present in the buffer area, a control device moves the A/R corresponding to the work area adjacent to the buffer area to the buffer area to rivet the fuselage panel.
