Note
Data security of the memory card
After setting up and activating the know-how protection, for encrypted data backup on the
memory card, previously backed up, non-encrypted data of the SINAMICS software will be
deleted. This is standard deletion procedure, in which only the entries on the memory card
are deleted. The data itself is still available and can be reconstructed.
To ensure know-how protection, we recommend the use of a new empty memory card. If you
cannot obtain a new memory card in the short term, you should delete all safety-related data
on the current memory card.
To completely delete your previous data on the memory card, you must reliably delete this
data using a suitable PC tool before activating know-how protection. The data is located on
the memory card in the "\\USER\SINAMICS\DATA" directory.
