Function Modules For Creating A Line Infeed In An Island Grid; Creating An Additional Vsm10 - Siemens SINAMICS S120 System Manual

Function modules for creating a line infeed in an island grid

In the project, click on "INFEED" under "Infeeds" and then select "Properties...".
● Under the "Function modules" tab, select the "Grid transformer" and "Grid droop control"
modules, and when required, select additional modules.
Note
Activation of the function modules by a higher-level control system
The function modules can also be activated by a higher-level control system. For this
purpose, parameter p0009 of the Control Unit must be set to "2" (defining the drive type
function module). You can then use parameter p0108[x].y = 1 of the Control Unit to activate
the individual function modules.
In this case, the object number of the INFEED must be used for the index "x".
The meanings of the "y" bits for the function modules for grid infeed are as follows:
• (Bit 03 = supplementary controls)
• Bit 04 = grid transformer
• (bit 07 = dynamic grid support)
• Bit 12 = grid droop control
The function modules are activated with p0009 = 0.
7.4.4

Creating an additional VSM10

If the drive device was commissioned with full DRIVE-CLiQ topology using an automatic
configuration, then the VSM10 modules are already in the topology. In this case, the number
should not be changed, but the assignment checked corresponding to the following chapter,
and if required adapted.
Procedure if the project was configured offline
In the project, double-click on "INFEED" under "Infeeds" and click on "Wizard..." in the
configuration window.
● Do not change anything in the first screen.
● Select "Number of VSMs:" in the second screen in the list box Select as required.
A VSM is entered in the "Number VSM" for each Active Line Module; this number of
VSMs must be incremented by 1 to create an additional VSM10.
● Click through the remaining screens without making changes and close the wizard.
● This adds an additional VSM10 to the topology.
