r947 Fault Memory
Display of the faults which have occurred at the last trips. Each fault number
has a fault value and a fault time assigned to it (see Chapter 7 for details of
fault numbers and fault values). The relationship between the responsible
parameters is shown in the diagram below.
The fault numbers for the last (8 max.) faults are stored under the indices of
parameter r947. The fault number for the current (not yet reset) trip is
indicated by r947.001, the fault number for the last reset fault is indicated by
index 9, the fault number of the last-but-one reset fault is indicated by index
17, etc. The entry "0" here means that no previous fault has occurred. In
contrast to the converter (SIMOVERT Master Drive FC, VC, SC), in the
case of the rectifier/regenerating unit only one fault can occur for each trip,
therefore the only significant indices are 1, 9, 17, 25, 33, 41, 49 and 57.
A fault value in the appropriate index of parameter r949 is assigned to every
fault number. This provides more detailed information on the type of fault.
Apart from this, for each trip, the fault time which is the actual value of the
operating hours counter (r013) is stored in parameter r748. The data for the
current (not yet reset) trip is present as "day", "hours" and "seconds" in
indices 1 to 3. The data for the already reset, previous trips is present in
groups of 3 elements on the following indices.

Indizes 9
Indizes 17
Plain text describing the fault numbers is available under the corresponding
index of parameter r951.
If the electronics supply voltage fails, all fault numbers are saved, but only
those fault values and fault times relating to the last trip are stored. After the
supply voltage has been restored, the other indices have the value "0".

r949 Fault Value
Interference value of the faults, permits a more precise diagnosis for many
fault numbers.
The fault values are saved in the same indices as the related fault numbers
(r947) - see parameter P947.

r951 Fault Texts List
List of fault texts; every fault text is saved in the index equivalent to its fault
number.
