Download and upgrade

Firmware download

The SINAMICS G120XA firmware version V1.03 can be downloaded here:  Registrierung notwendig  G120X_04712723_OA_1030005_BIOS_04703703.zip (15,6 MB)

Firmware upgrade

With an SD card, you can upgrade the SINAMICS G120XA inverter with older firmware version to this firmware version by following the steps as below:

  1. Download the required firmware to your PC from the source as above. Extract the files and transfer the unzipped files into the root directory of the SD card.

  2. Switch off the converter power supply.

  3. Insert the card into the converter slot until it latches into place.

  4. Switch on the converter power supply again. The converter transfers the firmware to its memory, which takes 5 to 10 minutes. While data is being transferred, the LED RDY on the converter stays red. The LED BF flashed orange with a variable frequency.

  5. At the end of the transfer, the LED RDY and BF slowly flash red (0.5Hz). The converter firmware will be incomplete if the power supply fails during the transfer. In this case, start again with step 2.

List of fault and alarms

The “alarmlist_*.xml” files are not necessary for the correct operation of the firmware. They only include an export of the “Alarm messages” text for the SINAMICS G120XA in the “xml” format. Customers occasionally request these exported texts so that they can further process them in their own applications or integrate them in external devices. Therefore, as far as the SINAMICS G120XA product is connected, no additional support can be provided here.

The list of fault and alarms in 6 languages including Chinese, English, German, Italian, French and Spanish can be downloaded here:  Registrierung notwendig  Alarm_list_in_6_languages.zip (313,5 KB)
