Embodiment Construction

[0032] Hereinafter, an example of the embodiment of the present invention will be described with reference to the drawings. In addition, the same code|symbol is attached|subjected to the same or corresponding part in each drawing.

[0033] figure 1 The structure of the machine control device of this embodiment is shown. figure 1 The machine control device 10 shown is, for example, a numerical control device that controls operations of machines such as machine tools and industrial robots according to programs. The machine control device 10 has a function of performing a diagnostic test of the safety function of the machine at regular intervals (time intervals).

[0034] As such diagnostic tests, diagnostic tests that cannot be performed during program execution are listed below.

[0035] (1) Power blocking circuit test

[0036] Actually perform power blocking and confirm the contact state of the power blocking circuit at this time, thereby confirming the normality of the po...

Abstract

The invention provides a machine control device, which avoids the occurrence of processing failure within a predetermined period of time and automatically performs a diagnostic test. The machine control device controls the operation of a machine on the basis of a program and performs a diagnostic test of the safety function of the machine at a predetermined time, the machine control device is provided with a diagnostic test time calculation part that calculates a predetermined time at which the diagnostic test is performed; a program execution time prediction part that predicts an end prediction time of the program before execution of the program; a diagnostic test execution determination part that determines whether or not the diagnostic test is executed at a predetermined time by determining whether or not the predicted end time (T2) of the program exceeds a predetermined execution time of the diagnostic test; and an execution part that executes the diagnostic test, and instructs thediagnostic test execution part to execute the diagnostic test before the program is executed before the predetermined execution time of the diagnostic test when the predicted end time of the programexceeds the predetermined execution time of the diagnostic test.

Description

technical field [0001] The present invention relates to a control device for controlling machines such as machine tools and industrial robots. Background technique [0002] It is known that, in machines such as machine tools and industrial robots, diagnostic tests are performed at regular intervals in order to prevent safety functions from being impaired due to malfunctions of mechanical components (for example, refer to Patent Documents 1 and 2). [0003] An example of such a diagnostic test is a diagnostic test (MCC blocking test) of a power blocking circuit for emergency stopping of shaft movement when a mechanical abnormality is detected. This diagnostic test actually performs power blocking, and detects an abnormality of the blocking circuit by checking the state of the contacts of the power blocking circuit at that time. This diagnostic test requires power interruption and therefore cannot be performed in automatic operation of the machine. Therefore, it is necessary...
