Features: The MCX314 is a DSP motion control chip developed by NOVA Electronics Co., Ltd. in Japan. It offers excellent performance, simple interfaces, easy programming, and reliable operation, making it widely applicable in motion control for CNC machine tools, robots, and other fields. The chip can interface with 8-bit or 16-bit data buses and implements motion control and real-time monitoring of position, speed, and acceleration for 4-axis 3-axis linkage through command, data, and status registers. It supports trajectory interpolation in three modes—linear, circular, and bit—with an output pulse frequency of up to 4MHz. Each axis has servo feedback input terminals, 4 input points, and 8 output points, which can be independently set to constant speed, linear, or S-curve acceleration/deceleration control modes. It also includes two 32-bit logical and actual position counters and status comparison registers to achieve position closed-loop control. This book provides a detailed introduction to the control principles of the MCX314, its interface circuits with MCS51, PC ISA, PCI buses, control software implemented in assembly and C language, and related technologies. Additionally, it covers the hardware and software methods for designing machine tool CNC systems based on the MCX314. The book is comprehensive, easy to understand, and all circuits and software examples have been tested. It is suitable for technical personnel engaged in the development of CNC systems and motion control.
