======================
The discontinued/cancelled hardware components NCU 561.3, 571.3, 572.3 and 573.3 of SINUMERIK 840D and 840DE have been innovated to secure the availability of a 10-year spare parts supply.
The innovated NCU 572.3 and 573.3 are/will be released for general availability in the spare parts business.
When replacing spare parts, carefully observe the compatibility with the NCU software.

The new NCU 561.3 and 571.3 will be described in a separate ProdIS Info when the right time comes.

Strategy in the spare parts business:

NCU 572.3
Predecessor  6FC5357-0BB22-0AE0  =>  successor  6FC5357-0BB23-0AA0

NCU 573.3
Predecessor  6FC5357-0BB33-0AE3  =>  successor  6FC5357-0BB33-0AA0

If there is no compatibility with the NCU software, the previous component should be used – or if this is no longer available, then an upgrade should be made to the specified update status or to the next higher update status in the meantime.

Depending on the inventory in the spare parts loop, spare part supply, supply as exchange and/or repair will be considered.
