Working with firmware versions

Firmware update/downgrade
The firmware must be updated if the functional scope is extended in a more recent version
and the corresponding functions need to be used.
The firmware must be downgraded if, for example, you want to use a lower version when
installing a spare part on a CU305 already upgraded with a higher version.
A firmware update/downgrade may take a few minutes. The RDY (READY) LED on the
CU305 lights up red (without flashing) to indicate the process is running.
Once all updates/downgrades are complete, the RDY (READY) and COM LEDs on the
Control Unit flash red at a frequency of 0.5 Hz and the relevant RDY (READY) LED on the
component flashes green/red at 2 Hz. To activate the firmware, carry out a POWER ON for
all components.
For automatic updates/downgrades when switching the system off/on, proceed as follows:
Factory setting after firmware downgrades
With a downgrade, there is a risk of errors in the conversion of the parameters!
We recommend:
 Back up the parameters on a memory card before carrying out the downgrade.
 After a downgrade, re-establish the factory settings.
 Afterwards, copy the parameterization back into the CU305 (see section "Handling

the ROM with parameters p0802, p0803 and p0804:
– p0802 = (0...100) as source (from the memory card), p0803 = (0/10/11/12) as target
(to the "ROM"), and p0804 = 2.
Note
Saving/loading all parameters via p0976 and p0977:
You can save or reload all parameters via parameters p0976 and p0977. For more
details, refer to the parameter description in the SINAMICS S110 List Manual.
