Problems solved by technology

[0002] In the existing servo driver, the main controller provides pulse direction signals to control the servo motor to perform corresponding actions. This method can only transmit information from the main controller to the servo driver in one direction, and cannot form a closed-loop feedback, and the amount of transmitted information is limited. Difficult to achieve more complex and precise motion control

Embodiment 1

[0034] Such as Figure 1 ~ Figure 4 As shown, a closed-loop control method is specifically applied to servo drives of machine tools, industrial robots, placement machines or transmission equipment, including the following steps:

[0035] S1 obtaining step, the servo drive obtains the execution command data sent by the main controller through the MECHATROLINK-Ⅲ communication protocol; the execution command data includes the speed control data, position data and operation status data of the servo motor.

[0036] Specifically, the specific process of the S1 acquisition step is as follows:

[0037] The S11 servo drive is connected to the main controller through the MECHATROLINK-Ⅲ communication protocol;

[0038] The S12 servo driver receives the execution instruction byte sent by the main controller;

[0039] S13 The servo driver stores the received execution instruction bytes in the buffer area.

[0040] S2 execution step, the servo driver drives the servo motor to perform cor...

Embodiment 2

[0056] Such as Figure 5 As shown, a closed-loop control device includes the following steps:

[0057] The acquisition unit 20 acquires the execution command data sent by the main controller 10 through the MECHATROLINK-III communication protocol; the execution command data includes the speed control data, position data and running status data of the servo motor 40 .

[0058] Specifically, the acquisition unit is connected with the main controller 10 through the MECHATROLINK-III communication protocol, and then receives the execution command byte sent by the main controller 10 and stores it in the buffer.

[0059] The execution unit 30 drives the servo motor 40 to perform corresponding actions according to the execution instruction data.

[0060] Specifically, the execution unit 30 first checks the data specifications of the execution instruction bytes stored in the cache area, then sorts the execution instruction bytes, and finally executes the instructions.

[0061] The fee...

Embodiment 3

[0065] Such as Figure 6 As shown, a servo driver includes a rectangular housing 60 , and a first circuit board 70 and a second circuit board 80 disposed in the housing 60 .

Abstract

The invention relates to a closed-loop control method,in particular to a closed-loop control method for a servo driver and a closed-loop control device for the servo driver. The closed-loop control method includes the following steps of obtaining,wherein the servo driver obtains execution instruction data sent by a main controller through the MECHATROLINK-III communication protocol; executing,wherein the servo driver drives a servo motor to execute corresponding movement according to the execution instruction data; feedback,wherein the servo driver feeds back conditions of the corresponding movement executed by the servo motor to a main controller through the MECHATROLINK-III communication protocol. According to the closed-loop control method,bi-direction data transmission can be achievedbetween the main controller and the servo driver,and the control accuracy and the control effect are improved.
