Adapting The Topology And The Vsm10 Assignments - Siemens SINAMICS S120 System Manual

7.4 Commissioning example for an infeed with voltage and frequency control for an island grid.
7.4.5

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 7-2
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 INFEED 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.
● The optional VSM10 for synchronizing to an external grid, must be connected to a free
DRIVE-CLiQ socket of the Control Unit.
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] = 5 (access level 4)
● The VSM10 with component number 8 is responsible for synchronizing the infeed with
island grid (VSM2 functionality).
INFEED.p0150 = 2 (access level 4)
INFEED.p0151[0] = 8 (access level 4)
● The VSM10 with component number 9 (when required) is responsible for synchronizing
the infeed with an external grid (VSM3 functionality).
INFEED.p0150 = 2 (access level 4)
INFEED.p0151[1] = 9 (access level 4)
Note
Parameters p5460[0]...p5474[0] are responsible for the VSM2 functionality.
Parameters p5460[1]...p5474[1] are responsible for the VSM3 functionality.
