近年来，随着变频器身功能的不断完善，交流调速技术有了长足的进步。如何在不同应用条件下充分开发变频器自身功能、有效的降低设备的改造成本已成为一个重要问题。与通常的控制方式相比，利用变频器直流制动功能实现交流拖动系统准确停车的设计方案省去了价值昂贵的变频器专用制动单元／制动电阻，有效降低了设备改造成本，工作稳定可，控制精度高。

VVVF能耗制动的理论分析通用变频器提供的制动方式主要有：能耗制动、再生制动、整流回馈等。在转动惯量较大的工况条件下，变频器厂家所建议采用的一般方式是外接制动电阻和制动单元的再生制动方式，某些情况下可以配合采用直流制动。这一设计思路基本为大多数目内用户所接受，并在实际使用中获得了较好的效果。但该方案需另外购买变频器厂家提供的专用制动单元／制动电阻，无形中增大了改造成本。 A6X30007971 MD VC CONVERTER,COMP+,IP20,3AC,480V+OPTS Siemens
