■ Overview

Modularity
SINAMICS G120 is a modular inverter system comprising a
variety of functional units. The main units are:
• the Control Unit (CU)
• the Power Module (PM)
The Control Unit controls and monitors the Power Module and
the connected motor using several different control types that
can be selected. It supports communication with a local or
central control and monitoring devices.
The Power Module supplies the motor in a power range 0.37 kW
to 250 kW (0.5 hp to 400 hp). The Power Module is controlled by
a microprocessor in the Control Unit. State-of-the-art IGBT tech-
nology with pulse-width modulation is used to achieve the high-
est degree of reliability and flexible motor operation. Compre-
hensive protection functions provide a high degree of protection
for the Power Module and the motor.
Furthermore, a large number of additional components are avail-
able, such as:
• Intelligent Operator Panel (IOP) for parameterizing, diagno-
sing, controlling and copying drive parameters
• Basic Operator Panel (BOP) for parameterizing, diagnosing,
controlling and copying drive parameters
• Line filters, Classes A and B
• Line reactors
• Braking resistors
• Sine-wave filters
• Output reactors
Safety Integrated
The SINAMICS G120 standard inverters are available in a num-
ber of different versions for safety-related applications. All Power
Modules are already designed for Safety Integrated. A Safety
Integrated Drive can be created by combining a Power Module
with the appropriate Fail-safe Control Unit.
The SINAMICS G120 fail-safe frequency inverter provides four
safety functions, certified in accordance with EN 954-1,
Category 3 and IEC 61508 SIL 2:
• Safe Torque Off (STO) to protect against active movement of
the drive
• Safe Stop 1 (SS1) for continuous monitoring of a safe braking
ramp
• Safely Limited Speed (SLS) for protection against dangerous
movements when a speed limit is exceeded
• Safe Brake Control (SBC) for controlling motor brakes that are
active in the de-energized state, e.g. motor holding brakes
The functions “Safe Stop 1” and “Safely Limited Speed” can
both be implemented without having to use a motor sensor or
encoder; the implementation cost is minimal. Existing systems in
particular can be updated with safety technology without the
need to change the motor or mechanical system.
The safety functions “Safely Limited Speed” and “Safe Stop 1”
are not certified for pull-through loads as in the case of lifting
gear and winders.
Additional information is provided in the part Highlights, section
Safety Integrated.
Efficient Infeed Technology
The innovative Efficient Infeed Technology is used in PM250 and
PM260 Power Modules. This technology allows the energy pro-
duced by motors operating in generator mode connected to
standard inverters to be fed back into the supply system. Addi-
tional cooling and additional space requirement in the control
cabinet can be avoided as components such as braking resis-
tors, brake choppers and line reactors are not required. Further,
wiring and engineering costs are significantly reduced. At the
same time, considerable savings can be achieved in terms of
energy consumption and operating costs.
Additional information is included in the part Highlights, section
Efficient Infeed Technology.
Innovative cooling concept and coated electronic modules
The innovative cooling concept and coated electronic modules
significantly increase the service life and usage time of the de-
vice. These features are based on the following principles:
• The power loss is exclusively dissipated using an external
heat sink
• Electronic modules not located in air duct
• Standardized convection cooling of Control Unit
• All cooling air from the fan is directed through the heat sink
STARTER commissioning tool
The STARTER commissioning tool simplifies the commissioning
and maintenance of SINAMICS G120 inverters. The operator
guidance combined with comprehensive, user-friendly functions
for the relevant drive solution allow you to commission the device
quickly and easily.

and Safety Integrated according to IEC 61508 SIL 2
■ Applications
SINAMICS G120 is ideally suited
• as a universal drive in all industrial and commercial applica-
tions
• e.g. in the automotive, textile, printing and chemical industries
• for higher-level applications, e.g. in conveyor systems
■ Design
SINAMICS G120 standard inverters are modular frequency in-
verters for standard drives. Each SINAMICS G120 comprises
two operative units – the Power Module and Control Unit. Each
Control Unit can be combined with each Power Module.
Guidelines for module selection
The procedure to select a complete SINAMICS G120 frequency
inverter should be as follows:
Control Units
The Control Unit performs closed-loop control functions for the
inverter. In addition to the closed-loop control, it has additional
functions that can be adapted to the particular application
through parameterization.
Two series of Control Units are available for SINAMICS G120
corresponding to their software packages (CU230 and CU240).
Each Control Unit comprises a defined I/O quantity structure, a
special fieldbus interface and possible additional safety func-
tions. The following Control Units and accessories are available
for standard SINAMICS G120 inverters:
CU230 Control Units
The CU230P-2 Control Units have been specifically designed for
pump, fan and compressor applications. The following three ver-
sions are available:
• CU230P-2 HVAC
• CU230P-2 DP
• CU230P-2 CAN
CU240 Control Units
Several Control Units are available in different versions:
• CU240E
• CU240S
• CU240S DP
• CU240S DP-F
• CU240S PN
• CU240S PN-F
1. Select a suitable Control Unit (depending on the required commu-
nication, hardware and software version and safety functionality)
2. Select a suitable Power Module (depending on the power and
technology required)
3. Select the optional and additional components. There are a large
number of components for expanding the system (e.g. line-side
power components, DC link components, load-side power compo-
nents, and supplementary system components). However, it
should be noted that not all of the components are required for all
of the Power Modules (example: Braking resistors are not required
for the PM250 and PM260 Power Modules!). The precise data is
provided in the technical specifications tables of the particular
components.

■ Design
Power Modules
The following Power Modules are available for the
SINAMICS G120 standard inverters:
PM240 Power Modules
PM240 Power Modules (0.37 kW to 250 kW / 0.5 hp to 400 hp)
feature an integrated brake chopper (for frame size FSGX exter-
nal) and are designed for drives without energy recovery capa-
bility. Generator energy produced during braking is converted to
heat via externally connected braking resistors.
PM250 Power Modules
PM250 Power Modules (7.5 kW to 90 kW / 10 hp to 125 hp) have
an innovative circuit design which allows line-commutated en-
ergy recovery back into the line supply. This innovative circuit
permits generator energy to be fed back into the supply system
and therefore saves energy.
PM260 Power Modules
PM260 Power Modules (11 kW to 55 kW / 15 hp to 75 hp) also
have an innovative circuit design which allows line-commutated
energy recovery back into the line supply. This innovative circuit
permits generator energy to be fed back into the supply system
and therefore saves energy. The PM260 Power Modules also have
an integrated sine-wave filter that limits the rate of rise of voltage
and the capacitive charging/discharging currents usually asso-
ciated with inverter operation.
Line-side power components
The following line-side power components are available for
SINAMICS G120 standard inverters:
Line filters
With one of the additional line filters, the Power Module reaches
a higher radio interference class.
Line reactors (for PM240 Power Modules only)
A line reactor reduces the system perturbations caused by
harmonics. This particularly applies in the case of weak line
supplies (line supply short-circuit power uK>1%).
Recommended line components
This is a recommendation for additional line-side components,
such as fuses and circuit-breakers (line-side components must
be dimensioned in accordance with IEC standards). Additional
information about the listed fuses and circuit breakers can be
found in Catalogs LV 1 and LV 1 T.
DC link components
The following DC link components are available for the
SINAMICS G120 standard inverters:
Braking Modules (only for PM240 Power Modules, frame
size FSGX)
A Braking Module and the matching external braking resistor are
required to bring drives with a PM240 Power Module, frame
size FSGX to a controlled standstill in the event of a power failure
(e.g. emergency retraction or EMERGENCY STOP Category 1)
or limit the DC link voltage during a short period of generator
operation. The Braking Module includes the power electronics
and the associated control circuit.
Braking resistors (for PM240 Power Modules only)
Excess energy in the DC link is dissipated in the braking resistor.
The braking resistors are designed for use with PM240 Power
Modules. They are equipped with an integrated brake chopper
(electronic switch). There is an optional plug-in Braking Module
for frame size FSGX.
Load-side power components
The following load-side power components are available for the
SINAMICS G120 standard inverters. This means that during op-
eration with output reactors or sine-wave filters, longer, shielded
motor cables are possible and the motor service life can be ex-
tended:
Output reactors (for PM240 and PM250 Power Modules only)
Output reactors reduce the voltage stress on the motor wind-
ings. At the same time, the capacitive charging/discharging cur-
rents, which place an additional load on the power unit when
long motor cables are used, are reduced.
Sine-wave filter (not for PM260 Power Modules)
The sine-wave filter limits the rate of rise of voltage and the
capacitive charging/discharging currents that usually occur with
inverter operation. An output reactor is not required.

Machinery Directive
The inverters are suitable for installation in machines. Compli-
ance with the Machinery Directive 98/37/EC requires a separate
certificate of conformity. This must be provided by the plant con-
struction company or the organization marketing the machine.
EMC Directive
• EN 61800-3
Variable-speed electric drives
Part 3: EMC product standard including specific test methods
The EMC product standard EN 61800-3 has been valid for elec-
tric drive systems since 07/01/2005. The transition period for the
predecessor standard EN 61800-3/A11 from February 2001
ended on October 1, 2007. The following information applies to
SINAMICS G120 frequency inverters from Siemens:
• The EMC product standard EN 61800-3 does not apply
directly to a frequency inverter but to a PDS (Power Drive
System), which comprises the complete circuitry, motor and
cables in addition to the inverter.
• Frequency inverters are normally only supplied to experts for
installation in machines or systems. A frequency inverter must,
therefore, only be considered as a component which, on its
own, is not subject to the EMC product standard EN 61800-3.
The inverter's operating manual, however, specifies the condi-
tions regarding compliance with the product standard if the
frequency inverter is expanded to become a PDS. For a PDS,
the EMC Directive in the EU is complied with by observing the
product standard EN 61800-3 for variable-speed electric
drive systems. The frequency inverters on their own do not
generally require identification according to the EMC Direc-
tive.
• In the Standard EN 61800-3 from July 2005, a distinction is no
longer made between “general availability” and “restricted
availability”. Instead, different categories C1 to C4 have been
defined in accordance with the environment of the PDS at the
operating location:
-Category C1: Drive systems for rated voltages < 1000 V for
use in the first environment
-Category C2: Stationary drive systems not connected by
means of a plug connector for rated voltages < 1000 V.
When used in the first environment, the system must be in-
stalled and commissioned by personnel familiar with EMC
requirements. A warning note is required.
-Category C3: Drive systems for rated voltages < 1000 V for
exclusive use in the second environment. A warning note is
required.
-Category C4: Drive systems for rated voltages ≥1000 V or
for rated currents ≥400 A or for use in complex systems in
the second environment. An EMC plan must be generated.
• The EMC product standard EN 61800-3 also defines limit val-
ues for conducted interference and radiated interference for
the so-called “second environment” (= industrial power sup-
ply systems that do not supply households). These limit values
are below the limit values of filter class A to EN 55011. Unfil-
tered inverters can be used in industrial environments as long
as they are part of a system that contains line filters on the
higher-level infeed side.
• With SINAMICS G120, Power Drive Systems (PDS) that fulfill
the EMC product standard EN 61800-3 can be configured
when observing the installation instructions in the product
documentation.
• A differentiation must be made between the product stan-
dards for electrical drive systems (PDS) of the range of stan-
dards EN 61800 (of which Part 3 covers EMC topics) and the
product standards for the devices/systems/machines, etc.
This will probably not result in any changes in the practical use
of frequency inverters. Since frequency inverters are always
part of a PDS and these are part of a machine, the machine
manufacturer must observe various standards depending on
their type and environment (e.g. EN 61000-3-2 for line har-
monics and EN 55011 for radio interference). The product
standard for PDS on its own is, therefore, either insufficient or
irrelevant.
• With respect to the compliance with limits for line supply har-
monics, the EMC product standard EN 61800-3 for PDS refers
to compliance with the EN 61000-3-2 and EN 61000-3-12
standards.
• Regardless of the configuration with SINAMICS G120 and its
components, the machine construction company (OEM) can
also apply other measures to ensure that the machine com-
plies with the EU EMC Directive. The EU EMC Directive is gen-
erally fulfilled when the relevant EMC product standards are
observed. If they are not available, the generic standards (e.g.
DIN EN 61000-x-x) can be used instead. It is important that
the conducted and emitted interference at the line connection
point and outside the machine remain below the relevant limit
values. Any suitable technical measures can be applied to en-
sure this.
SEMI F47
SEMI F47 is an industry standard relating to the immunity to volt-
age dips. This includes the requirement that industrial equip-
ment must be able to tolerate defined dips or drops of the line
supply voltage. As a result, industrial equipment that fulfills this
standard is more reliable and productive. In the SINAMICS G120
product family, the PM240 and PM250 Power Modules fulfill the
latest SEMI F47-0706 standard. In the case of a voltage dip, de-
fined in accordance with SEMI F47-0706, these drives either
continue to supply a defined output current, or using an auto-
matic restart function, continue to operate as expected.

■ Overview
Example of CU240S DP-F Control Unit
The Control Unit performs closed-loop control functions for the
inverter. In addition to the closed-loop control, it has additional
functions that can be adapted to the particular application
through parameterization. Several Control Units are available in
different versions:
•CU240E
•CU240S
•CU240SDP
•CU240SDP-F
•CU240SPN
• CU240S PN-F
Safety Integrated functions
The following Safety Integrated functions are integrated in the
CU240S DP-F and CU240S PN-F Control Units and, with the ex-
ception of the “Safe Brake Control”, can be implemented without
external circuit elements:
The SINAMICS G120 fail-safe frequency inverter provides four
safety functions, certified in accordance with EN 954-1,
Category 3 and IEC 61508 SIL 2:
• Safe Torque Off (STO) to protect against active movement of
the drive
• Safe Stop 1 (SS1) for continuous monitoring of a safe braking
ramp
• Safely Limited Speed (SLS) for protection against dangerous
movements when a speed limit is exceeded
• Safe Brake Control (SBC) for controlling motor brakes that are
active in the de-energized state, e.g. motor holding brakes
The functions “Safe Stop 1” and “Safely Limited Speed” can
both be implemented without having to use a motor sensor or
encoder; the implementation cost is minimal. Existing systems in
particular can be simply updated with safety technology without
the need to change the motor or mechanical system.
The safety functions “Safely Limited Speed” and “Safe Stop 1”
are not certified for pull-through loads as in the case of lifting
gear and winders.
Safety functions have been extended with firmware V3.2.
Additional information is provided in the part Highlights, section
Safety Integrated.
