As of version 4.7 HF7, the SINAMICS S120 Runtime firmware as download is not subject to any export restrictions, as the output frequency has been limited to 550 Hz.

It is not subject to the Iran embargo, and is not listed in the EC Dual Use regulation. (AL = N).
It is not a US product (ECCN = N).

If higher output frequencies are required, then the "High output frequency" license must be purchased, article no.: 6SL3074-0AA02-0AA0. It can also be ordered as Z option J01 together with the CF card, see 104020669.

The "High output frequency" license is subject to export restrictions, and currently has export code: AL:3E225, ECCN: N SH code: 0.

Alternatively, a new memory card (CF) with the following article number can be used:

  • Without performance expansion: Article no.: 6SL3054-0FB10-1BA0
  • With performance expansion firmware option: Article no.: 6SL3054-0FB11-1BA0

List of faults and alarms

The "alarmlist_*.xml" are not necessary for the correct operation of the firmware and the associated STARTER. They only contain a text-based export of the "Alarm messages" of the S120 in the "xml" format (this format guarantees a correct text-based representation, independent of the wide range of fonts that exist worldwide; this means that they can be converted error-free into other formats).
 This text-based export is occasionally requested by customers to process them further in their own applications respectively load them onto external devices. As a consequence, as far as the S120 product is concerned, no additional support can be provided here.
