A1045 alarm in Siemens V70 Drive indicates Configuring data is invalid. This means the drive detected corrupted parameter files in its non-volatile memory during startup, which must be overwritten.
Cause: An error was detected when evaluating the parameter files saved in the non-volatile memory.
Remedy: Save the parameterization using the “SAVE” function on the BOP. This overwrites the incorrect parameter files in the non-volatile memory and the alarm is withdrawn.
