基于POWERLINK的分布式电动机漏电保护节点设计

摘要

Motor leakage protection is important to guarantee the safe operation of the motor. The design of the distributed motor leakage protection node based on POWERLINK industrial Ethernet is presented. The hardware composition, communication interface and POWERLINK communication configuration are described in the paper. The designs of the POWERLINK interface and the object dictionary configuration are emphasized. The leakage protection node can be connected with host node to build a distributed motor leakage protection system.%电动机漏电保护对保证电动机安全运行具有重要意义，设计基于POWERLINK工业以太网的分布式电动机漏电保护节点，阐述其硬件组成、通信接口和POWERLINK通信配置，介绍POWERLINK接口设计和对象字典配置。该漏电保护节点可与主站联接，构建分布式电动机漏电保护系统。
