Description

technical field [0001] The invention belongs to a servo motion controller circuit, in particular to a novel high-speed, high-precision multi-axis servo motion controller circuit. Background technique [0002] CNC machine tools are the core and foundation of modern manufacturing systems. The motion control system of modern CNC machine tools requires high-speed calculation, fast interpolation, ultra-high-speed communication, ultra-high-speed spindle operation, and high-precision positioning. In order to realize the processing of components with complex shapes, the CNC machine tool must require the motion control system to be able to control interpolation motion, such as linear interpolation, circular interpolation, bit interpolation and continuous interpolation. [0003] my country is a manufacturing power, not an industrial power. In the field of motion control, there is still a big gap with developed countries. The weak independent innovation ability greatly affects the imp...
