Problems solved by technology

[0002] Most of the existing servo drive unit test equipment adopts a stand-alone test mode in which one servo drive unit corresponds to one servo motor, and it is difficult to achieve mass testing
The automation of the test process of the servo drive unit is low, it takes a long time for the testers, and the labor cost is too high
On the other hand, in the traditional stand-alone test mode, it is difficult for testers to uniformly control different test units, so it is also difficult to quickly and accurately obtain the final batch test results in batch testing

Embodiment 1

[0034] Such as figure 1 , 2 As shown, a modularized servo drive unit integrated test platform based on bus control includes:

[0035] A servo drive unit assembly 100, the servo drive unit assembly 100 includes a plurality of servo drive units 110;

[0036] The controller 200 is used to control the plurality of servo drive units 110;

[0037] Wherein, the plurality of servo drive units 110 are connected to the controller 200 through an Ethernet automatic control EtherCAT bus.

[0038] The EtherCAT bus is a field bus system based on Ethernet, and EtherCAT is a deterministic industrial Ethernet. EtherCAT bus control usually includes three control modes: serial link, timing search and independent request. The distribution of the right to use the bus in the serial link mode is realized through three control lines. The three control lines include: bus available, bus request and bus busy signal lines. Among them, all the functional components send a request to the bus controller via a comm...

Embodiment 2

[0043] Such as figure 1 , 2 As shown, on the basis of Embodiment 1, the test platform further includes: a handheld teach pendant 300, and the handheld teach pendant 300 is connected to the controller 200 through the TCP / IP protocol, The controller 200 inputs control instructions through the handheld teach pendant 300. Further, there are multiple groups of the servo drive unit assembly 100, and each group of the servo drive unit assembly 100 is equipped with a handheld teach pendant 300.

[0044] Further, the handheld teach pendant 300 and the controller 200 are electrically connected via a network cable 310 or wirelessly connected via a WiFi network.

[0045] The handheld teach pendant 300 is equivalent to an input device of the controller 200. By writing about the handheld teach pendant 300, the operator can perform test operations without standing in a fixed position in front of the console. With WiFi network wireless connection, the operator can even stay away from the console ...

Embodiment 3

[0047] Such as figure 1 , 2 As shown, on the basis of Embodiment 1 or 2, further the plurality of servo drive units 110 in the same group of the servo drive unit assembly 100 are connected in series and then connected to the controller 200 through the EtherCAT bus.

[0048] This embodiment means that each EtherCAT bus is connected in series with only the plurality of servo drive units 110 in one set of the servo drive unit assembly 100.

Abstract

The invention relates to a modular servo drive unit comprehensive test platform based on bus control. The platform comprises a plurality of servo drive unit components, each servo drive unit componentin the plurality of servo drive unit components at least comprising a servo drive unit; a controller used for controlling the plurality of servo driving units corresponding to the plurality of servodriving unit assemblies; wherein the plurality of servo driving units are connected with the controller through an Ethernet automatic control EtherCAT bus. According to the invention, through an EtherCAT bus control mode, a group of multiple servo driving units are connected in series to carry out multi-machine test of a bus mode, so that a more accurate, faster and more controllable test effect is achieved, the consumption of test time is reduced, and the labor cost is reduced.

Description

Technical field [0001] The invention relates to the field of servo drive test equipment, in particular to a modular servo drive unit comprehensive test platform based on bus control. Background technique [0002] Existing servo drive unit testing equipment mostly adopts a single-machine test mode in which one servo drive unit corresponds to one servo motor, and it is difficult to achieve mass testing. This makes the test process of the servo drive unit less automated, takes a long time for testers, and costs too much labor. On the other hand, in the traditional stand-alone test mode, it is difficult for testers to uniformly control different test units, so it is also difficult to obtain the final batch test results quickly and accurately in batch testing. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a comprehensive test platform for modularized servo drive unit based on bus control in view of the shortcomings of the p...
