Problems solved by technology

[0003] In fact, the multi-axis drivers on the market now integrate the traditional driver solutions together to use one, which is not much different from the traditional servo driver in essence, but the volume is reduced, but the cost is not reduced. Not very cost-effective
In the realization of the EtherCAT slave station, each axis is realized by an ESC chip, so that there will inevitably be a delay in the multi-axis motion control, so that the real-time performance cannot be achieved in the control

Abstract

The invention relates to the field of data processing and particularly relates to an EtherCAT bus multi-axis slave station system. The system comprises a slave station controller for controlling multi-axis data, a microprocessor for processing the multi-axis data and a multi-axis driving circuit. The slave station controller is connected with the multi-axis driving circuit through the microprocessor, and the slave station controller performs multi-axis control through an object dictionary. The system further comprises an optoelectronic isolator, an interface with a network transformer and an electrically erasable programmable read-only memory EEPROM. According to the system, the problems of high cost and large occupied space of a traditional driving scheme are solved, and the technical problem of multi-axis control of a single chip is solved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to an EtherCAT bus multi-axis slave station system. Background technique [0002] Under the general trend of "Industry 4.0", intelligent manufacturing has become the main theme of the times and the main direction of the manufacturing industry. In the manufacturing industry, automation and intelligent drive technology will play an increasingly important role. This is an innovative challenge centered on the improvement of sustainable productivity and efficiency, thus providing inexhaustible resources for the upgrading and transformation of traditional industries and the long-term development of emerging industries. power. Servo drives are particularly important as key components of industrial robots and CNC machine tools. There is a one-to-one relationship between a traditional servo drive and an AC servo motor, and one servo drive can only drive one AC servo motor. Such drives canno...
