Embodiment Construction

[0023] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 Shown, the present invention comprises the following steps:

[0025] 1) The detection step of the switching value input interface of the servo drive is used to detect whether the industrial computer of the servo drive controls the switching value signal output board to output high level or low level. If the level is consistent with the output level of the output board, that is, when both are low or high, it is judged that the switching value input interface of the servo driver is correct, otherwise it is judged that the switching value input interface is wrong. This step includes step 11 and step 12; step 11: The drive of the industrial computer is connected to the digital input interface of the servo driver. After a certain period of time after all the digital signals in the output board are at high level, t...

Abstract

The invention discloses an automatic factory test method and an automatic factory test device for a servo driver, and relates to the field of the servo driver. At present, keys of a switching value input port and a pulse value input port are detected only, and detection is easily interfered by human factors, and the servo driver cannot be detected comprehensively, so the defects of low product percent of pass, irrational parameters and large discreteness are caused. The detecting method comprises the steps of detecting a servo driver switching value input interface, detecting a servo driver switching value output interface, detecting a servo driver pulse value input interface, detecting a servo driver encoder signal output interface, and detecting a servo driver open collector output interface. An industrial personal computer and each board card which is socketed with the industrial personal computer are combined for automatically detecting the servo driver, so that the automatic factory test method and the automatic factory test device reduce the human factors, improve the detecting accuracy, reduce the labor intensity, accurately adjust the parameters, avoid adopting a special instrument for adjusting, finish the detection once, improve the detecting efficiency, simplify the detecting process and further improve the detecting efficiency.

Description

【Technical field】 [0001] The invention relates to the field of servo drives, in particular to a method and device for fully automatic detection of servo drives when they leave the factory. 【Background technique】 [0002] Servo drives have been widely used in CNC machine tools, packaging machinery, printing and dyeing textile machinery, robots and other industries to meet the needs of various mechanical transmissions. In order to improve the qualified rate of servo drive products, the servo drive must be tested before the servo drive is packaged. The detection content includes all input and output port functions, restoration and adjustment of servo driver parameters. The input and output ports include digital input interface, digital output interface, pulse input interface, analog input interface, encoder output interface, open collector output interface, and analog monitoring output interface. When the servo drive is tested, it is necessary to adjust some parameters of the...
