4.4 Use of function blocks
When working with function blocks, proceed as follows (irrespective whether the function block has
instance codes or not):
1. Inserting the corresponding library in the library management,
menu command WindowLibrary management
2. Declaring the function block.
Parameterisable function blocks
Some function blocks of the controller libraries also have codes that serve to change certain settings
during operation or display actual values and status information.
In contrast to the 9400 HighLine servo inverter, the codes of these function blocks are not created
automatically but by the user in the PLC project.

Tip!
Lenze recommends that no changes be made to the initialisation values of codes of
parameterisable function blocks.
Example for creating codes for function blocks:
1. Insert LenzeServoDriveVxxyy.lib library in the library management
2. Insert L_SdRampGenerator POU in the Application program
3. Carry out configuration:

Note!
If new library versions are incorporated in the PLC project, the initialisation values of
codes of parameterisable function blocks are reset to the Lenze settings.
If necessary, the codes must be reset in the Parameter Manager.
