                        说明
                        只有在速度降低时实际负载也降低的情况下,才能用降低频率的方法来减少变频器的负载 (例如
                        被驱动负载的速度特性是平方关系转矩特性)                                       

常用的施耐德器型号大全具体如下图所示： 三、接线与接线图 由于施耐德器用较多的可能是交流所以我们就着重的讲讲这种接线以及附带接线图展示。而且还可以像平常开关一样采用手动接通或是断开操作，咨询：，看看是不是符合实际使用要求。，其中包含了额定电压、电流和操作等数据一一核对，
