Title:
SERVO DRIVE SYSTEM AND BRAKING CONTROL METHOD AND APPARATUS THEREFOR, AND SERVO DRIVER
Document Type and Number:
WIPO Patent Application WO/2023/087604
Kind Code:
A1
Abstract:
A servo drive system (1000) and a braking control method and apparatus (200) therefor, and a servo driver (400) and a storage medium. The method comprises: when a servo electric motor (300) in a servo drive system (1000) needs to be braked, determining a three-phase current of the servo electric motor (300) (S11); and determining a braking mode of the servo electric motor (300) according to the three-phase current, and controlling, according to the three-phase current, the servo electric motor (300) to switch between a first braking mode and a second braking mode during braking of the servo electric motor (300), wherein the first braking mode is used for controlling a servo driver (400) to output a zero voltage, and the second braking mode is used for turning off an output of the servo driver (400) (S13).
