In the conventional processing machine control device as described above, when an error occurs, it is necessary to operate the operation unit 1 and select the alarm diagnosis screen in order to know the cause of the error. Since the cause is displayed as an alarm number, it is not possible to immediately know what the cause of the error is just by looking at the alarm number, and the operator must consider measures to eliminate the error. Furthermore, after removing the cause of the error, the operator must operate the operation unit 1 to select the previous work screen again, so it takes a lot of time to start machining work again after an error occurs. During this time, machining work is interrupted and the operating rate of the processing machine decreases, and since the operator must refer to the instruction manual based on the alarm number to determine how to eliminate the cause of the error, operator errors may occur. However, there is a problem in that this further increases system down time.

The device is equipped with a previous screen automatic return means for automatically returning to the previous screen.

[For production]

In the processing machine control device of the present invention, the current work data displayed on the display section is stored in the screen storage means at the same time as an error occurs, and an alarm diagnosis screen is automatically displayed on the display section by the display means. At the same time, the alarm number, the cause of the error, a message indicating the countermeasure, and the countermeasure location are automatically displayed on the alarm diagnosis screen, and the cause of the error is removed according to the contents of the message and countermeasure location on this display screen. After the reset by the alarm reset means, the work data before the error occurrence stored in the double-sided storage means is automatically read out to the display section, and the screen before the error occurrence is automatically returned. Therefore, according to the present invention, the time required to eliminate the cause of the error, that is, the system down time, is shortened, and the operating rate and productivity of the processing machine are improved.
