Drive and control integrated numerical control system and FPGA configuration method

Abstract

The invention provides a drive and control integrated numerical control system. The numerical control system is provided with a plurality of drive shafts and can drive the drive shafts through a numerical control drive program. The numerical control drive program is provided with instruction lines capable of driving a plurality of drive shafts, and the instruction lines can be achieved through a single chip SOC. The single chip SOC is provided with a first processor, a second processor and an FPGA unit, and the first processor, the second processor and the FPGA unit are accessed through an AXIbus. The invention further provides a configuration method of the drive and control integrated FPGA. The controller is highly integrated with a drive and control integrated system, wiring and installation of the system are simplified, multi-axis synchronization is achieved more easily and effectively, and data interaction between a numerical control system and a driver is simpler, faster and morereliable.

Description

technical field [0001] The invention relates to the fields of numerical control processing technology and robots. The invention specifically relates to a drive-control integrated numerical control system and an FPGA configuration method. Background technique [0002] Current CNC machining equipment or robots are generally composed of a control part (NC system) and an execution part (driver), which are relatively independent of each other. Traditional CNC machining equipment or robot architecture is generally composed of CNC system plus multiple single-axis servo drives, and they work independently with power supply. In the traditional servo motor control technology, there is an architecture of MCU plus FPGA. FPGA implements a relatively simple current loop, because FPGA logic implements complex algorithms, adding or changing algorithms has great difficulty and complexity, is not easy to implement, and requires continuous optimization and adjustment. At the same time, the ...

Problems solved by technology

FPGA implements a relatively simple current loop, because FPGA logic implements complex algorithms, adding or changing algorithms is very difficult and complex, it is not easy to implement, and requires continuous optimization and adjustment

At the same time, the relative independence of each part of this technology leads to complex wiring of the whole system, complex power supply system, large space occupation, and inconvenient installation.
