Hello

We have an aplication with Masterdrives AFE(6SE7031-2EF80) and Materdrives Drive on a crane.
Every time that we power the Masterdrives AFE on, and precharging is done, the Masterdrives AFE
show´s us the fould F003(Line overvoltage).What could be the fault? Is the fault on Voltage sensing board or maybe on the CUSA board? We also couldnt get connected with Drivemonitor and Masterdrives AFE?

All possible solutions are welcome.

Kindly, note that i have the same fault accured F003& F007 wich make The trip. i still troublshouting the fault.
Ihad swap all control boards VSB,CUSA,main CB interface, k7. tarce the line voltage but still trip.

Your input high appreciated.
