2.4 Device access protection
This function extension is available from version 06.00.00!
Various tasks can be executed via the functions of the device access protection:
• Password protection
• Only authorised persons (with password knowledge) may read/change all parameters of the
inverter.
• Non-authorised persons (without password knowledge) can only access the max. 32
parameters of the user menu.
• Device personalisation
• Only inverters and memory modules personalised with a specific binding ID can be used in
the system.
Note!
If password protection/device personalisation is used:
• Inform the end customer that Lenze can only provide restricted service for the devices
with access protection.
• It is not possible for Lenze to modify a replacement device via special accesses in such
a way that it cooperates with a personalised memory module.
• From firmware version 4.2 onwards, the X400 keypad supports the alphanumeric
entry of a password. Keypads with lower firmware versions cannot be used for the
entry.
