A1045 alarm in siemens sinamics V90 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. Because of this, under certain circumstances, several of the saved parameter values were not able to be accepted.
Remedy:
- Save the parameterization in SINAMICS V-ASSISTANT using the “Copy RAM to ROM” function or on the BOP.
- This overwrites the incorrect parameter files in the non-volatile memory – and the alarm is withdrawn.
