Procedure
Proceed as follows to activate know-how protection:
1. Select the inverter in the STARTER project and select "Know-how protection drive device
/ Activate ..." in the shortcut menu.
2. Enter your password. Length of the
password: 1 ... 30 characters.
For the password, we recommend
that you only use characters from
the ASCII character set. If you use
any character for the password,
then if changes are made to the
Windows language settings after
activating know-how protection,
errors can occur when subsequent-
ly checking the password.
3. In this screen form, press the "Copy RAM to ROM" button. This means that you save
your settings so that they are protected against power failure.
You have activated know-how protection.
Backing up settings on the memory card
When know-how protection is activated, you can save the settings to the memory card using
p0971.
To do this, set p0971 = 1. The data is written to the memory card encrypted. After saving,
p0971 is reset to 0.
