11.7 Access protection
11.7.1 Write access protection
Optionally a write access protection can be installed for the inverter parameters.
Write access protection only restricts parameterisation via keypad and »EASY
Starter«. Write access protection via network is not restricted. Irrespective of
the write access protection that is currently set, a higher-level controller, OPC-
UA server, or any other communication partner connected to the inverter is
always provided with full read/write access to all parameters of the inverter.
After activating the write access protection, you have to enter a valid PIN to
remove the write access protection. Note down the defined PIN(s) and keep this
information in a safe place! If you lose the PIN(s), the inverter can only be disa-
bled by resetting it to the delivery status. This means, all parameter settings
made by the user get lost!
Details
Usually the write access protection function is implemented by the mechanical engineer/
OEM , for example to protect the inverter against incorrect parameterisation by non-author-
ised persons. For diagnostic purposes, a read access to all parameters is always possible.
The write access protection allows for the following configurations:
Full write access
•
Write access only to favorites or (when knowing PIN1) to all parameters
•
No write access or (when knowing PIN2) full write access
•
No write access or (when knowing PIN1) write access only to favorites or (when knowing
•
PIN2) to all parameters
The following table compares the four possible configurations:

If PIN1 and PIN2 are set identically, a write access to all parameters is possible after the PIN has been
entered correctly.
