Abstract

The invention relates to a double-axis servo driving system, and relates to the field of automatic control. The system comprises a master control module, a power driving module, a first motor, a second motor, a first mechanism execution mechanism and a second mechanical execution mechanism; the master control module comprises a master control chip, a first motor position feedback circuit, a secondmotor position feedback circuit, a first mechanical execution mechanism position feedback circuit, a second mechanical execution mechanism position feedback circuit and an EtherCAT bus communicationcircuit; the master control chip is electrically connected with the power driving module; the power driving module is electrically connected with the first and second motors; the first motor is connected with the first mechanism execution mechanism, and the second motor is connected with the second mechanism execution mechanism. The system can provide different feedback types, the control precision is improved greatly, and single-chip configuration can be minimized.

Description

technical field [0001] The embodiments of the present invention belong to the field of automatic control, and in particular relate to a two-axis servo drive system. Background technique [0002] AC servo drive is an important part of CNC machine tools, packaging machinery, electronic special equipment, robots and other industries. With the continuous advancement of manufacturing industry upgrading, it provides a huge market for the development of the servo industry. The high-performance servo drive system based on AC servo drives tends to be fully digital, AC, highly integrated, modularized and networked, and can provide convenient, flexible, accurate and fast drives. In the existing technology, the servo drive system can be divided into a single-axis servo drive system and a multi-axis servo drive system. A single-axis servo drive system refers to a system in which a servo driver drives and controls a servo motor. The system generally uses multiple servo drives to drive mu...
