完善的马达保护
完善的马达保护是对马达运行过程中的各种运行状况的详细信息进行采集跟踪，通过对故障报警，保护动作(保护脱扣)，以及动作廷时时间的设定来实现及时准确的保护，保证生产的安全。同时经通讯，可以对马达运行状况的详细信息在上位机上进行实时监测，并经计算机数。在设备可能产生重大故障前，越限报警可及时提醒管理人员进行处理，避免了不必要的停机而对正常生产造成影响，限度地保证设备运行的有效性。
当马达运行参数达到预置的报警值时，保护装置仅进行报警，不触发脱扣;但当越限值达到预置的脱扣值时，保护装置进入脱扣触发延时。在预置脱扣延时时间内若设备恢复正常运行，则取消脱扣执行;而如果超过延时时限，则保护装置发出脱扣信号，驱动执行元件动作，停止电机运行。在马达控制装置实现各项保护功能的同时，各种保护信息也由装置生成并经通信接口上送至计算机管理系统。
马达保护的特点:
各种保护功能已内置在装置中，可根据实际需要进行配置。
通过设置软件可轻松选择所需的保护功能。
可根警并延时脱扣，只报警不脱扣或直接进入延时脱扣保护。
通过对保护脱扣复位模式的预先设定，用户可选择故障保护脱扣的复位方式，不同的保护功能具有的复位方式不一样。
自动复位
运程复位
本地复位
本地及远程复位
配套的操作面板MD直接显示电机电参量及故障信息。
