Embodiment Construction

[0080] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples.

[0081] The performance index detection method of this embodiment realizes automatic testing of the servo system. The servo system includes at least one servo motor. The performance index detection method includes: when receiving a detection instruction, performing a step response test on each servo motor in turn, At least two of a parabolic response test, a closed loop frequency response test, and a circularity response test. Wherein, the test items, the quantity of the test items, and the test order of the test items can be set according to actual needs. The test command can be generated manually, for example, by pressing a button, that is, to complete each test item of each motor in the servo system with one key; the test command can also be generated automatically, for example, by means of a script, set the cycle of test co...

Abstract

The invention discloses a performance index detection method of a servo system and a computer storage medium. The servo system includes at least one servo motor, and the performance index detection method includes: when receiving the detection instruction, performing at least two of the following tests on each servo motor in sequence: step response test, parabolic response test, closed-loop frequency response test and circularity response test. The invention realizes the automatic performance index test of each servo motor in the servo system, reduces the burden of test personnel and greatly improves the test efficiency.

Description

technical field [0001] The invention relates to the technical field of detection and maintenance of a numerical control system, in particular to a performance index detection method of a servo system and a computer storage medium. Background technique [0002] CNC machine tools have been widely used in high-tech industries such as aerospace, automobiles, and consumer electronics, which have greatly improved production efficiency and machining accuracy, and have become an important basis for technological progress and technological development. However, according to statistics, the production loss caused by the failure of the CNC system reaches hundreds of billions of RMB every year. Therefore, the stability and performance evaluation of CNC machine tools have attracted widespread attention and research at home and abroad. [0003] At present, the performance indicators of the servo parameters of each servo motor in the servo system can only be tested and adjusted individuall...
