Abstract

This invention relates to a three-in-one AC servo driver including a master controller, a control module, a supply module and multiple servo motors, in which, one driver can connect with multiple motors, a supply module needed by the multiple motors and the control module are put in a same module, thus, a repeat part is saved for the control unit part such as communication interface, a display unit and input / output unit and the bus volume of the IGBT module on the supply module can be shared and reduced.

Description

technical field [0001] The invention relates to an AC servo driver, in particular to a three-in-one AC servo driver. Background technique [0002] The current multi-axis motion control system architecture belongs to centralized control, that is, it includes a main controller, which controls the servo drive through traditional wiring or high-speed communication to realize multi-axis interpolation such as linear / arc of the servo motor. sports. [0003] AC servo motors are often used in processing machines with more than three axes or multi-axis working systems. Most of the current designs are one driver connected to one motor. Even if the current one-to-many design can connect multiple motors, it is designed as an expansion module design, that is, to connect more motors, the power module used to drive the motors will be expanded. In this way, the savings in performance, cost and volume will not produce much effect, and there is no substantial saving in wiring and installatio...
