首先这个不知是不是输入缺相
supply loss: one or more of the power(input) supply phases is open-circuit.
而这两个又是什么呢?
power supply: one or more of the intemal power supplies is out of tolerance.
phase seqvence: connections to E1 and E3 are not the same phases as are connected to L1 and L3 investigate and correct.
supply loss: one or more of the power(input) supply phases is open-circuit
电源缺相:一相或多相电源输入端开路中(即无电压)power supply: one or more of the intemal power supplies is out of tolerance.
电源(问题):电源输入端的一相或多相不在正常范围内(电压不正常)
phase seqvence: connections to E1 and E3 are not the same phases as are connected to L1 and L3 investigate and correct
相序问题:E1和E3的相序连接与L1和L3的连接相序不一样或不正确
