过电压现象是变频器运行中最常见的故障之一 ,直流制动与再生制动功能是防止过电压产生的最主要的手段 ,而再生制动功能是解决因外力拖动而使电机处于再生状态所引起的变频器过电压的唯一有效措施
Overvoltage phenomenon is one of the most common faults in inverter operation. DC braking and regenerative braking functions are the most important means to prevent overvoltage. Regenerative braking function is to solve the problem of regenerative braking caused by external drag The inverter is over voltage caused by the state of the only effective measures
