After acknowledgement, the faults that have not been removed are located in the fault buffer
as well as in the fault history. For these faults, the "fault time coming" remains unchanged
and the "fault time removed" remains empty.
If less than eight faults were shifted or copied into the fault history, the memory locations with
the higher indices remain empty.
The inverters shifts the values previously saved in the fault history each by eight indices.
Faults, which were saved in indices 56 ... 63 before the acknowledgement, are deleted.
Deleting the fault history
If you wish to delete all faults from the fault history, set parameter p0952 to zero.
