Hi every one,
I am getting a problem about ATV61 inverter of Schneider brand. It is normally useing to control a fan which it's power is 30KVA/ 3 phases/380VAC. After then it displays a error: nLP ( no line power: L1, L2,L3) Although there is a power line 380V/3phases. I checked the input voltages on Power board (the board controlls 3SCRs and 6 IGBTs), checks all the DC power supplies for example 5VDC, +/-15VDC, 22VDC, 10,3VDC...then enough voltages, it seem OK but remain to alarm a error nLP. So, Every one help me the problem? Thank you.
P/S: Please give me the STI 008717's IC datasheet.
