Abstract

The invention discloses a servo drive device and a servo control system. The servo drive device includes a power module, a processing module and a coding interface module. The output ends of the power module are respectively connected with each power input end of the processing module and the coding interface module to provide power supply for the processing module and the coding interface module. The coding interface module comprises at least a first position feedback interface unit, a second position feedback interface unit and a power supply interface unit. The output ends of the first position feedback interface unit and the second position feedback interface unit are connected with the processing module, and correspondingly used for acquiring code data of an incremental encoder and an absolute-type encoder and delivering the code data to the processing module after corresponding processing of the code data. The input end of the power supple interface unit is connected with the output end of the power module, and provides working voltage for an external encoder connected with the first position feedback interface unit or the second position feedback interface unit selectively according to configuration parameters. The servo drive device and the servo control system can be compatible with multiple types of encoders including photoelectric rotary encoders with the same or different working voltages.

Description

technical field [0001] The invention relates to the technical field of numerical control, in particular to a servo drive device and a servo control system. Background technique [0002] With the in-depth development of industrialization and automation technology, motor control as a basic link, especially high-end servo motor control, has become an indispensable part that affects work efficiency and performance in fully automated production lines, industrial robots, and numerical control systems. [0003] For example, in the three-loop control theory of the servo motor, in addition to the current loop, the feedback of the speed loop and the position loop needs to obtain real-time data of the motor shaft for processing and control. How to obtain the motor shaft data efficiently, quickly and accurately has become the most important index affecting the control accuracy and response speed in motor control. [0004] Obtaining real-time data of the motor shaft movement by addition...
