6.19 Updating the firmware

6.19 Updating the firmware
The firmware version must be updated if new functions are made available in a later version
and the operator wishes to use them.
The firmware for the SINAMICS drive system is distributed in the system. Firmware is
installed on each individual DRIVE-CLiQ component and the Control Unit.
The Control Unit fetches its firmware automatically from the memory card during booting,
which means that it does not need to be updated separately. The memory card only needs to
be replaced with a card containing the more recent firmware version.
When upgraded, the firmware is saved (non-volatile) in the DRIVE-CLiQ component. The
firmware in the DRIVE-CLiQ components is also stored on the memory card and can be
automatically copied from the memory card to the DRIVE-CLiQ components during initial
commissioning by means of the factory setting p7826 = 1 (as of firmware version 2.5).
Once the project has been downloaded or automatic configuration has been carried out, the
firmware is upgraded on all the connected DRIVE-CLiQ components. This upgrades or
downgrades all DRIVE-CLiQ components to the firmware release that matches the memory
card.
This may take a few minutes, and is indicated by the green/red flashing of the READY-LED
of the relevant component and by the orange blinking (0.5 Hz) of the Control Unit.
Parameter p7827 indicates the progress.
When all updates have run, the READY-LED of the Control Unit flashes orange at 2 Hz and
the READY-LED of the relevant component flashes green/red at 2 Hz. For the firmware to be
activated, a POWER ON must be carried out for the components.
For individual components, STARTER dialogs (Drive Unit -> Configuration -> Version
Overview) can be used to read the firmware version or start a firmware upgrade manually for
specific components.
Note
The versions of the DRIVE-CLiQ components and that of the Control Unit can differ. An
overview of the versions is provided on the memory card in the file "content.txt" or can be
read out via the parameter r7825.
