Reconfigurable Design and Implementation of Gravure Engraving Motion Controller Based on FPGA
Reconfigurable logic has gained relevance in high-speed computer numerical control (CNC) digital controller. In this paper, a design of three-axis high speed gravure engraving machine motion controller based on programmable logical device is proposed. In the design of the hardware, the prevalent technology of Filed Programmable Gate Array is applied, which enhances the flexibility of the hardware. All the circuits and algorithms are developed using hardware description language. A novel solution for acceleration and deceleration control of servo motors is implemented in FPGA. This system is already applied in a high speed (8K) gravure engraving machine, and the results prove that this controller based on a low-cost FPGA platform is highly precise and of great universality.
