Undesirable response or data loss if the memory card is improperly handled
For disturbance-free operation of the control electronics (CUD), the memory card
recommended by Siemens must only be inserted in the device when the SINAMICS DCP is
switched-off and in a no voltage condition. Inserting the card when operational can result in
undefined states of the device with the corresponding effects.
Ideally, the memory card is ordered when purchasing the DCP, and is installed before
commissioning.
If the memory card is not inserted from the very beginning, and is only inserted after being
requested to do so, for example by Technical Support, then it must first be completely
emptied.
This prevents that data possibly saved on the memory card overwrites the actual parameter
assignment of the DCP.
To avoid data loss when removing the memory card, it must be logged off from the device
as described in Section "Safely removing the memory card".
Note
The memory card supplied from Siemens as option S03 in
cludes, when supplied, a dump of
the internal device firmware. These files are required to update the firmware. These fil
e
s can
be deleted for other applications.
Before you use the card for the functions described in this chapter, copy these files to a local
folder of your PG/PC and delete the files on the memory card.
Parameter data sets
Parameter data sets represent all of the parameters of a project - including the DCC charts
and the project itself. The parameter data sets differ depending on configuration and
application.
Different data volumes can be saved in the three memory areas:
● ROM: Four parameter data sets with the indices 0, 10, 11, and 12
● The parameter data set with the index 0 is active in the RAM
● Memory card: Depending on the free storage space, up to 101 parameter data sets
(indices 0 to 100)
Note
The DCC library itself is not saved as a part of the par
ameter data set.
