Parameters without write protection
Certain parameters are excluded from the write protection in order not to restrict the
functionality and operability of the drives. The list of these parameters can be found in the
SINAMICS S120/150 List Manual in Section "Parameters for write protection and know-how
protection", Subsection "Parameters with WRITE_NO_LOCK".
The "Restore factory settings" function can also be used when write protection is activated.

Know-how protection

The "Know-how protection" function prevents, for example, strictly confidential company
know-how for configuration and parameter assignment from being read by unauthorized
persons.
The know-how protection requires a password. The password must comprise at least 1 and
a maximum of 30 characters.
Note
Password security
You are responsible for the security of your password. Whenever possible, use a password
with sufficient length (min. eight characters); use upper- and lower-case letters and special
characters.
The know-how protection is a pure online function. Therefore, establish a direct connection
to the Control Unit before setting the password.
