1、过压保护（F2）：此功能是为了防止出现直流母线电压过高，造成电容或者IGBT等器件损坏，变频器判断过压的检测点在直流母线，以3AC380-480V交流电压等级为例， 正常直流母线电压约为1.35倍的交流进线电压计算，通常为DC 520V-DC540V之间，当变频器所驱动的负载惯量比较大，快速降速时，或者变频器拖动位能性负载下放时，电机转子实际转速高于变频器输出给电机的转速，造成负载反拖电机，电机处于发电运行状态，机械能转化为电能，通过变频器的逆变桥IGBT反并联二极管回馈到变频器的直流母线，由于直流母线的电容容量固定，随着回馈能量的增加，直流母线电压随之升高，达到一定的限值可能导致器件的损坏，所以此时必须抑制过压趋势，比如投入制动单元制动电阻，较直流电压控制器等等。
