Siemens SINAMICS S120 Function Manual page 881

In the following diagram, two Motor Modules (400 V, output ≤ 250 kW, pulse frequency 2 kHz)
are connected to interface X101 and two Motor Modules (400 V, output > 250 kW, pulse
frequency 1.25 kHz) are connected to interface X102.
Note
The OFFLINE topology automatically generated in the Startdrive commissioning tool must be
manually modified, if this topology was wired.

Topology example: Line Modules and Motor Modules connected in parallel
Line Modules in Chassis format and Motor Modules in Chassis format of the same type and
connected in parallel can be connected to one DRIVE-CLiQ socket of the Control Unit
respectively in vector control.
In the following diagram, two Active Line Modules and two Motor Modules are connected to the
X100 or X101 socket.
Note
The offline topology generated automatically in the Startdrive engineering tool must be
changed manually if this topology has been wired.
