Its has measured each phase come up value 0,01. (On motor) and for wire was 0,07. We tried to run the motor by using other wire and plug into power point 3 phases and motor was run ok each phase show 7,8 Amperes.
For Siemens Sirius temperatur monitor relay, we changed it already. Once it was connected to existing wire the tripped light also on.
I just wonder is it posible the output power of inverter below 380 ? Each phase shows 277 volts, 284 volts and 268 volts.
I have set the value in inverter according to motor name plate and started it by pressing bottom at inverter, the motor was turning. But we cannot start it by using PC from control room.😢
