| Abstract: | This paper introduced the principle of limited speed as well as hardware realizing. The speed is measured by a simple and high-precision way and displayed by the chip MAX-7219, and the displacement is measured through the chip MAX197. The working curve of the axis can be displayed on computer in real time. The value of the limited speed that we measured is in accord with the practical value. |
