ELM7231-9018
概要

ELM72xx-9018伺服电机EtherCAT终端具有集成的绝对值接口,在非常紧凑的设计中提供高伺服性能。基于磁场定向电流和PI速度控制的快速控制技术,支持快速和高动态的定位任务。通过I²T模型计算对过压和欠压、过流、终端温度或电机负载等众多参数进行监测,可提供最大的运行可靠性。
使用单线技术(OCT),通过现有的电机电缆以数字方式传输信号,省去了编码器电缆。从AM81xx系列中读取合适电机的电子识别板的选项使即插即用解决方案在调试期间提供最大的便利性。
该产品还配有额外的I/ o,例如两个数字输入,可用于检测末端位置或锁存位置,以及用于直接连接制动电阻以消耗反馈能量的额外输出。

特点
自动读取电子识别板
TwinSAFE STO/SS1,集成逻辑
可插拔连接技术
综合路径控制
交付范围包括推入式连接器和用于连接OCT电机电缆的护罩。
