Adapting the topology and the VSM10 assignments

Double-click on "Topology" in the project; the topology view appears.
The topology looks like this after the above commissioning steps, for instance:
Figure 7-4
The numbers in brackets to the right of the components in the topology view are the
"Component numbers".
● The VSM10 for the closed-loop control functionality of the infeed must be connected to
the -X402 DRIVE-CLiQ socket (booksize format: -X202) of the INVERTER infeed.
● The VSM10 for synchronization with the power supply (on the primary side of the grid
transformer) must be connected to the -X401 DRIVE-CLiQ socket (booksize format:
-X201) of the INFEED drive.
You must use the expert list to check the assignments of the VSM10 components present in
the project and correct these where necessary.
The following settings refer to the topology shown above.
● The VSM10 with component number 3 is responsible for the closed-loop control
functionality of the infeed.
INFEED.p0140 = 1 (access level 4)
INFEED.p0141[0] = 3 (access level 4)
● The VSM10 with component number 4 is responsible for synchronizing the infeed with a
power grid (VSM2 functionality).
INFEED.p0150 = 1 (access level 4)
INFEED.p0151[0] = 4 (access level 4)

Performing additional parameter settings in the expert list

The following table provides an overview of the most important adjustable parameters with
typical values and notes for a power grid application.
This overview should provide help when commissioning the system. It does not replace the
information in the previous chapters or the parameter descriptions and function charts in the
List Manual.
Depending on the application, in individual cases, it may be necessary to change
parameters, which are not listed in the tables.
