Host computer performance characteristics:

1. Using servo motors, servo controllers, and their supporting control units as driving components, the motor has a long lifespan

2. Adopting a hollow gear reduction system, it has low power consumption, low noise, high efficiency, and strong reliability

3. Adopting Zhongtai data acquisition card, the data acquisition system has a functional data acquisition module, suitable for various operating systems such as popular Windows series, high stability Unix, and professional data acquisition and analysis systems such as LabVIEW/LabWindows CVI software environment. And it comes with 16 parallel analog inputs, 3 counters, 16 digital inputs, and 16 digital outputs.

4. Adopting a direct insertion transmission device ensures high positioning accuracy, long service life, low friction, high-speed operation, and forward and reverse rotation, greatly improving the accuracy of the whole machine's translation, displacement, and speed

5. It has a position restriction function, making certain experiments with position restriction requirements safer and faster

6. Extremely wide measurement range, applicable to standards of multiple countries

7. Adopting the principle of integrated design, regardless of the configuration of the host, modify the corresponding parameters of the computer (parameters can be retained for a long time) without the need for circuit adjustments

8. High precision return positioning function, regardless of the return speed, can accurately return to the starting position, accelerate the test speed, and improve work efficiency

9. The commonly used parameter memory function, such as test speed, enables users to be in this parameter state as soon as the machine is turned on, greatly facilitating their use

10. The operation is flexible and convenient, with two working modes: constant motion and jog. Users can easily set them freely to adapt to different situations or habits

11. It has multiple protection functions: adjustable upper and lower limit protection, emergency stop protection, etc
