With the advancement of industrial upgrading, mechanical numerical control and automation is one of the important ways for enterprises to improve production efficiency, improve enterprise efficiency and obtain sustainable competitive advantage. As driving part, servo is widely used in the numerical control automation and plays an important role. This article studies multi-motor control servo driver based on single encoder feedback. The servo control system has multiple servo motor driver interface, so it can control the synchronous operation of many motors or independent operation of each motor. And through the parameter configuration, one of these can be chosen. It has flexible control and good applicability. Various kinds of position feedback can be compatible through position feedback interface circuit, which overcomes the disadvantages of the existing servo control system which can only support a form of encoder. It is easy to use with lower cost, and is easy to promote.
