Overview
Example: SINAMICS G120, frame sizes FSA to FSF
Example: SINAMICS G120, frame size FSGX
PM240 Power Modules, frame sizes FSA to FSF have an inte-
grated brake chopper to which an external braking resistor can
be connected via terminals DCP/R1 and R2 (see DC link compo-
nents).
PM240 Power Modules, frame size FSGX do not have an inte-
grated brake chopper. For these devices, there is an optional
pluggable braking module to connect a braking resistor.
The PM240 Power Module can be used to couple the DC links of
up to 10 Power Modules. This functionality is used for applica-
tions such as safe power-down after power failure or kinetic buff-
ering (the DC link is supplied in the generator mode with the ki-
netic energy of the load so that the DC link voltage can be
maintained).
The PM240 Power Module is also designed for safety-oriented
applications. In conjunction with a Fail-safe Control Unit, the
drive can be turned into a Safety Integrated Drive (see Control
Units).
The permissible cable lengths between inverter and motor are
limited. Longer cables can be used if output reactors are con-
nected (see load-side power components).
Line reactors are available to minimize line harmonics (see line-
side components).
Frame size FSA of the PM240 Power Module is available only
without integrated line filter to class A. A base filter is therefore
available so that class A can be achieved. A class B base filter
is also available so that class B can be achieved (see line-side
power components).
Frame sizes FSB and FSC of the PM240 Power Module are avail-
able both with and without integrated class A line filter. For com-
pliance with class B, PM240 Power Modules with integrated
class A line filter must be fitted additionally with a class B base
filter (see line-side components).
Power Modules with integrated class A line filter are suitable for
connection to TN supply systems. Power Modules without inte-
grated line filter can be connected to grounded (TN, TT) and
non-grounded (IT) supply systems.
