Four, software introduction

1, Taiwan imported AC servo motor, stable performance, reliable, with over current, over voltage, over speed, overload and other protective devices. Speed ratio of up to 1:5000.

2, electrical control line with reference to international standards, in line with the national testing machine electrical standards, strong anti-interference ability, to ensure the stability of the controller, the accuracy of the experimental data.

3, automatic transmission: according to the load size automatically switch to the appropriate range, to ensure the accuracy of measurement data; to achieve a real sense of the physical zero, gain adjustmenttest force measurement, automatic zero calibration, and save, no part of any simulation of regulation, control of highly integrated circuits

4, save conditions: control datasample test conditions can be made into modules, convenient batch test;

5, automatic transmission: the speed of the moving beam in the test process can be automatically changed according to the preset program, but also can be changed manually;

6, automatic calibration: the system can automatically realize the calibration accuracy of the calibration;

7, dynamic preservation: the end of the experiment, the test data and curves automatically save;

8, the process of realization: test process, measurement, display and analysis are completed by the computer;

9, batch test: the samples on the same parameters, one set after distal;

10, test software: Chinese WINDOWS interface, menu tips, mouse operation;

11, display the way: data and curves with the dynamic display of the test process;

12, curve traversal: after the completion of the test, the curve can be re analyzed, with the mouse can be found in the curve of the corresponding test data;

13, curve selection: according to the need to select the stress - strain, force - displacement, force - time, displacement - time curve for display and print;

14, test report: according to the user requirements of the format and print the report; with the network interface, data transmission, storage, printing and printing network transmission, can be connected with the internal LAN or Internet.

15, limit protection: with programmable and mechanical two level limit protection;

16, automatic shutdown: after the test samples, the moving beam automatic stop;

17, overload protection: when the load exceeds the maximum value of the 3-5%, automatic shutdown;

Automatic and manual test results of the two models to automatically form a report, so that the data analysis process is simple.
