Write and know-how protection
The inverter offers the option to protect configured settings from being changed or copied.
Write protection and know-how protection are available for this purpose.
Write protection prevents converter settings from being inadvertently changed. If you work
with the STARTER, the write protection is only effective online. The offline project of the
Starter is not write-protected.
The write protection applies to all user interfaces, and thus also to parameter changes via a
fieldbus.
The write protection is not password-protected.
