| 概要 |
具有集成解析器接口的EL7211伺服电机EtherCAT终端以非常紧凑的设计为AM8100和AM3100系列电机提供高伺服性能，最高可达4.5 a (Irms)。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。
通过计算I²T模型监测过压和欠压、过流、终端温度或电机负载等众多参数，提供最大的运行可靠性。EtherCAT作为一种高性能系统通信，而CAN-over-EtherCAT (CoE)作为应用层，可以与基于pc的控制技术实现理想的接口。最新的功率半导体保证了最小的功率损耗，并在制动时能够反馈到直流链路。16个led显示状态，警告和错误信息以及可能的活动限制。 |
