Embodiment Construction

[0041] Embodiments of the present invention will be described in detail below with reference to the drawings. In the following embodiments of the present invention, one type of machine tool will be described as an example, but the present invention can also be applied to industrial machines and industrial robots in addition to this type of machine tool.

[0042] Fig. 1 is a block diagram of an internal data observation device of a control device according to a first embodiment of the present invention. The data observation device 1 shown in FIG. 1 is a data observation device for observing internal data of a control device 2 of a machine tool. For example, the machine tool drives servo motors along the X-axis and Y-axis directions to transport the table, drives the servo motor along the Z-axis to transport the spindle, and processes workpieces fixed on the table. Here, the X axis, the Y axis, and the Z axis are the respective axes of the XYZ three-axis orthogonal coordinate s...

Abstract

A data observation device observes internal data of a control device for controlling a machine tool, an industrial machine, an industrial robot, or the like which has at least one drive shaft driven by one selected from a servo motor, a spindle motor. The device includes: means which specifies observational data targeted for observation; means which specifies trigger data used to determine a timing of a trigger for starting and / or terminating acquisition of the observational data; means which sets a trigger condition for applying the trigger based on a value of the trigger data; and means which judges whether or not the trigger condition is satisfied in the control device, selectively starts and terminates acquisition of a value of the observational data, and displays the acquired observational data.

Description

technical field [0001] The present invention relates to a data observation device for observing internal data of a control device for controlling a machine tool, an industrial machine, or an industrial robot in order to investigate and adjust the control characteristics of a servo motor or a spindle motor. For the data inside the control device, for example, the abnormal signal and alarm signal of the drive control device and detector of the motor that are not output to the outside, or the flag used in the interface between the NC and the drive control device, etc., can be triggered, and the data can be processed. A data observation device for observing the internal data of the control device. Background technique [0002] In Patent Document 1, an industrial machine monitoring method and its device are proposed as the subject, and an industrial machine monitoring method and its device are characterized in that the operating state of the industrial machine is measured and rec...
