Know-how protection

Know-how protection
The know-how protection is used to encrypt configuring/engineering know-how, and protect it
against being changed or copied.
The settings of the inverter are protected by a password.
If the password is lost, only default settings are possible.
The active know-how protection provides the following:
● All setting parameters are invisible.
● Parameters cannot be changed with a commissioning tool, e.g. Operator Panel or
STARTER.
● It is not possible to download the inverter settings with the Starter or via a memory card
● It is not possible to use the trace function in the STARTER.
● Deleting the alarm history
● The STARTER dialog screens are disabled. The expert list in the STARTER contains
only display parameters.
In the case of active know-how protection, support by technical support personnel is only
possible with the consent of the machine manufacturer.
Copy protection
In conjunction with the copy protection, the inverter settings can be coupled only to a single,
pre-defined hardware.
Know-how protection with copy protection is possible only using the recommended Siemens
card.
