Overview

The "know-how protection" (KHP) function prevents, for example, strictly confidential
company knowledge 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.
The know-how protection is a pure online function. Therefore, establish a direct connection
to the Control Unit before setting the password.
Know-how protection with and without copy protection.
To protect your drive unit settings against unauthorized copying, in addition to know-how
protection, you can also activate copy protection.
