10.36 Drive Control Chart (DCC)
● Step 4
Copy the OEM folder to an empty memory card.
Note
The memory card supplied from Siemens as option S01 or S02 includes, when supplied,
a dump of the internal unit software. These files are only required to update software.
These files can be deleted for all other applications of the memory card. Copy the files
into a local folder of your PG/PC and delete the files on the memory card, before you use
the card for the functions described in this chapter.
● Step 5
Insert the Memory card into the switched-off drive and switch on (POWER ON). The DCB
library is copied into the non-volatile memory (ROM) in the drive during power-up. The
process is complete as soon as the power-up has ended (operating state 7.0 reached).
● Step 6
Switch device off/on (POWER OFF / POWER ON). After the new power-up, the DCC is
ready.
● Repeat steps 5 and 6 on additional SINAMICS DCM drives.
Note
If DCC is installed in the drive, the power-up time increases by approx. 10 s.
Note
This procedure does not transfer the STARTER parameter assignments into the unit. In
order to transfer the parameter assignments from STARTER into the drive, the "Load into the
target system" function must be run in STARTER.
10.36.2 CPU time load through DCC
Calculating the DCC blocks requires CPU time. If the CPU time becomes meager, you have
to check whether all the activated blocks are required and whether all the function blocks
used need to be computed within the same sampling time.
The CPU time load can be reduced by either deactivating blocks or assigning used blocks to
a runtime group with a longer sampling time.
