Description

technical field [0001] The present invention relates to a servo motor control system and method, more specifically, it relates to an STM32-based servo motor integrated control system and method, and belongs to the technical field of servo motor control. Background technique [0002] In the field of industrial control, PLC occupies a large market share in low-end automation equipment. The mainstream PLC brands in the world (such as Siemens and Omron) have strong technical accumulation. PLC has short development cycle, high reliability, programming Language (such as ladder diagram) is easy for engineering and technical personnel to accept and other advantages. Therefore, PLC has insurmountable advantages in low-end non-standard and non-batch industrial automation products. [0003] Although PLC occupies a large market share in today's main low-end industrial automation products, the cost of PLC is high in high-volume control tasks. In addition, the current PLC servo driver c...
