A control system is an operating system that automatically controls the mechanical movement of an experimental device according to predetermined requirements. As for the servo motor, the control system is the important part of the indispensable, therefore, the design of the control system is directly related to the performance of the servo motor, the technical personnel by Hiroaki letter as we explain the servo motor control system design:

A control system is an operating system that automatically controls the mechanical movement of an experimental device according to predetermined requirements. As for the servo motor, the control system is the important part of the indispensable, therefore, the design of the control system is directly related to the performance of the servo motor, the technical personnel by Hiroaki letter as we explain the servo motor control system design:


1、connection of servo driver


Servo system wiring is very simple, only need to comply with the provisions of access to the corresponding plug. The three-phase power line L1, L2, L3 plug into the CPN1, servo motor plug into the CN2, the encoder plug access CNP2, control line plug access CN1. When debugging the program, it is necessary to use servo motor''s special software and connect it to the servo system CN3 through the RS422 interface.


对于CN1控制线接法如表1所示。


2、servo driver parameter settings


The system adopts positioning control, servo driver has two main sets of parameters, a set of basic parameters, another group of expansion parameters, according to the system requirements, set the basic parameters, including NO.0, NO.1, NO.2, NO.3, NO.4, NO.5, NO.7, NO.18, NO.19, extended parameters have to be set according to the specific situation. You can also set the parameters via the servo setup software SETUP221E. In the process of servo motor debugging, it is recommended to set the speed model for servo motor point test.


3 、 touch screen program design


The establishment of the initial screen, the button switch are respectively arranged on the screen, the switch were written on pressure, pressure, + origin regression, automatic adjustment, pressure correction, servo stop words, which corresponds to the situation above write relay. The control and parameter display screens are shown in figures 2 and 3.



The system is also equipped with manual adjustment function, to ensure the timely adjustment of the problems automatically remedied. On the touch screen, the indicator light is set up to display the working state at this time. At the same time, in the middle part of the manual and automatic indicator light, the pulse output indication is set, that is, the servo motor operation instructions, when the pulse output, there will be "pulse output" of the red indicator light. When no red indicator lamp is displayed, that is to say, the motor is out of order. At this time, the operator needs to query the fault according to the abnormal letters displayed on the servo driver, which is simple and convenient.
Servo motor control system design points to share here. The design of control system is very important for servo motor, so we must master the method when designing and setting. We hope that the above content will be helpful to you.
