Abstract

The invention relates to a four-axis integrated servo driver and a servo drive control method. It mainly integrates the control and driving of four-way motor, so as to effectively reduce the number ofmulti-axis integrated master control chips, simplify the control circuit structure, and effectively reduce the production and maintenance costs. The structure of the controller mainly includes control circuit and power circuit. The control circuit comprises a first substrate, an MCU chip arranged on the first substrate, an encoder interface module, a communication module, a low-voltage power conversion module and a first row of pins. The power circuit comprises a second substrate, a rectifier and power soft start module arranged on the second substrate, a power drive module, a voltage conditioning sampling module, a brake control module, a current sampling chip, a current conditioning module, an energy storage capacitor and a second row of pins. The power circuit comprises a second substrate, a rectifier and power soft start module arranged on the second substrate, a power drive module, a voltage conditioning sampling module, a brake control module, a current sampling chip, a currentconditioning module, an energy storage capacitor and a second row of pins.

Description

technical field [0001] The invention belongs to the field of industrial automation control, and in particular relates to a four-axis integrated servo drive and a servo drive control method. Background technique [0002] With the release of the "Made in China 2025" strategy to strengthen the country, my country's industrial automation industry has been booming, and as the core and key technologies of intelligent manufacturing and intelligent equipment, industrial control systems, servo motors, drives, and reducers and other devices have also been obtained. Vigorously promote and develop. Servo drives are the core components of industrial automation applications and are devices that convert electrical energy into kinetic energy. [0003] At present, there are many types of domestic servo drives, but most of them are single-axis servo drives. In industrial automation applications, multiple motor shafts are often required to be driven and controlled in coordination. If multiple ...
