【Abstract】 To improve the real time performance and speed of multi-axes coordinated motion control system, an IC is developed. The principle and structure of the IC are suggested using digital integration method controlled by 3-D contour motion. The way of realizing sub-circuits of CPU’s reading-writing module, instruction queue, motion control and auxiliary control is presented. VHDL language is then used to describe the circuits, and the above-mentioned methods and circuits are tested. The simulation indicates that the circuits can fulfill all the predicted functions. Besides, the frequency of driving pulse of 3-axis is higher than 1 MHz and is thus more reliable compared with the existing multi-axes coordinated methods and circuits.更多还原
