2. NOTES ON USING THE CPU 315F-2 PN/DP
The CPU 315F-2 PN/DP is a CPU that is shipped with two integrated interfaces.
- The first interface is a combined MPI/PROFIBUS-DP interface that can be used on the
PROFIBUS DP as Master or as Slave to connect distributed peripherals/fieldbus devices with
very fast response timing.
Moreover, the CPU can be programmed here by means of the MPI or also PROFIBUS DP
- The second interface is an integrated PROFINET interface.
It allows for using the CPU as a PROFINET IO controller to operate distributed peripherals on
the PROFINET. The CPU can be programmed by means of this interface also!
- At both interfaces, frequency converters and also fault-tolerant IO devices can be used.
Notes:
- In Module H01, the CPU 315F-2 PN/DP is used as IO controller on the PROFINET and as
master on the PROFIBUS DP.
- To operate this CPU, a micro memory card is required!
- The addresses of the input and output modules can be parameterized in the case of this CPU.

Modularity
SINAMICS G120 is a modular converter system that consists of different functional units. The two
basic building blocks are the Control Unit (CU) and the Power Module (PM).
The Control Unit controls and monitors the power module and the connected motor in several
control modes that can be selected. It supports communication with a local or central controller as
well as with monitoring devices. In addition to controlling, other functions are available that can be
adapted to the respective application through corresponding parameter assignment.
The control units are available in the following types:
● Standard CUs (CUs without safety oriented functions)
– CU240S
– CU240S DP like the CU240S but with PROFIBUS DP interface (PROFIdrive Profile 4.0)
– CU240S PN like the CU240S but with PROFINET interface (PROFIdrive Profile 4.0)
● CUs with safety oriented functions
– CU240S DP-F like the CU240S DP but with integrated safety oriented functions
The Power Module provides the motor with a performance range of 0.37 KW to 90 KW. The control
unit controls the power module by means of a micro processor. For highly reliable and flexible
motoring, the most modern IGBT technology with pulse width modulation is used. Comprehensive
protection functions provide a high measure of protection for the power module and the motor.
The power modules are available in the following types:
● Power Module PM240 with DC braking functions, supply voltage 3 AC 400V
The PM240 has an integrated brake chopper, and is designed for drives without power recovery for
the network. Possible regenerative energy is converted into heat by means of brake resistors that
are connected externally.
● Power Module PM250 with energy regeneration capability, supply voltage 3 AC 400V
● Power Module PM260 with energy regeneration capability, supply voltage 3 AC 690V
Power modules PM250 and PM260 have an innovative circuit concept which makes line
commutated power recovery possible. This innovation allows for returning regenerative energy to the
network, and thus saves energy.
Control units and power modules can be combined into any configuration. In this training document,
the control units CU240S DP and CU240S PN are described, together with the Power Module
PM240.

Automation and Drives - SCE
Optional Additional Components
Numerous supplementary components are available for the SINAMICS G120, such as:
• Basic Operator Panel (BOP)
With the Basic Operator Panel BOP -that can be inserted in the control unit- drives can be started
up, current operations can be monitored, and individual parameters can be set. In addition, the BOP
provides a function for copying parameters in a time-saving way.
• PC Converter – Connecting Set (PC Connection Kit)
This kit is used for controlling and starting up a converter directly from the PC, provided the
corresponding software (STARTER) is installed. The startup tool STARTER on CD ROM is included
in the PC Converter Connection Set.
• Brake Relay
With the brake relay, you can set up a connection between the power module and an electromechanical motor brake. Thus, the motor brake can be controlled directly with the control unit.
• Safe Brake Relay
With the safe brake relay, you can establish a connection between the power module and an
electrical-mechanical motor brake. Thus, safe brake controls can be implemented directly with the
control unit according to EN 954-1 Safety Category 3 and IEC 61508 SIL 2.
• MicroMemoryCard (MMC)
On the MMC, you can store the parameter assignment of the converter. If servicing is required, the
plant is immediately ready after the converter is replaced and the data is copied back from the
memory card. The associated slot is located on top of the control unit.
• Line-Side Power Components
• Network Filters Class A and B
With an additional network filter, the Power Module PM240 attains a higher radio interference
class.
• Line Reactors
A line reactor is needed if the system fault level is high, for two reasons: on the one hand, to
protect the converter itself from harmonic currents and overloads, on the other hand to limit
system perturbation to the permissible values.

Automation and Drives - SCE
• Intermediate Circuit Components
• Brake Resistors
By means of the braking resistors, excess energy of the intermediate circuit is reduced. The
braking resistors are intended for use with the PM240. It has an integrated brake chopper
(electronic switch).
• Power Components on the Output Side
They allow for longer, shielded motor cable lengths for operation with output reactors or LC filters
and sinusoidal filters; in addition, the life of the motor is extended.
• Output Reactors
Output reactors reduce the voltage load on the motor winding. At the same time, the capacitive
charge reversal currents are reduced which additionally strain the power unit when longer motor
cables are used.
• LC Filters and Sinusoidal Filters
LC filters and sinusoidal filters limit the voltage rise rate and the capacitive charge reversal
currents that usually occur at converter operation. Output reactors are then no longer needed.
Safety Integrated
The converter built-in units SINAMICS G120 offer variants of safety oriented applications. All power
modules are already fail-safe units. If a power module is combined with a corresponding failsafe
control unit, this drive becomes a Safety Integrated Drive.
The failsafe frequency converter SINAMICS G120 offers four safety functions, certified according to
EN 954-1, Kat.3 and IEC 61508 SIL 2:
• Safe Stop 1 (SS1)
• Safely Limited Speed (SLS)
• Safe Brake Control (SBC)
• Safely switched-off torque (STO)
Innovative Cooling Concept and Painted Electronic Modules
The innovative cooling concept of the electronic module and painting the module extend its life or
use considerably, and results in the following:
• Dissipation of power loss exclusively by means of the external heat sink
• Electronic modules not in the air duct
• Consistent convection cooling of the control unit
• The air flow of the fan blows exclusively through the heat sink
PROFIdrive Profile 4.0
The user data structure of the cyclical/acyclical communication channel is specified for PROFIBUS
and PROFINET in the PROFIdrive Profile, Version 4.0.
The PROFIdrive Profile specifies for the converters how a master/controller can access the
converters (slaves/devices) by means of cyclical or acyclical data transmission.
Note:
PROFIdrive for drive technology is standardized and described in the following document: Literature:

3.3 Safety Precautions and Warnings
Prior to installing and starting up the SINAMICS G120, the following safety related guidelines and
warnings have to be noted.
General
Warning
This equipment contains dangerous voltages and controls potentially dangerous rotating
mechanical parts. Non-compliance with the warnings or failure to follow the instructions
contained in this manual can result in loss of life, severe personal injury or serious damage
to property.
Protection in case of direct contact by means of SELV / PELV is only permissible in areas
with equipotential bonding and in dry indoor rooms. If these conditions are not fulfilled, other
protective measures against electric shock must be applied e.g. protective insulation.
Only suitably qualified personnel should work on this equipment, and only after becoming
familiar with all safety notices, installation, operation and maintenance procedures
contained in this manual. The successful and safe operation of this equipment is dependent
upon its proper handling, installation, operation and maintenance.
The power supply, DC and motor terminals, the brake and thermistor cables can carry
dangerous voltages even if the inverter is inoperative. Wait at least five minutes to allow he
unit to discharge after switching off the line supply before carrying out any installation work.
It is strictly prohibited for any mains disconnection to be performed on the motor-side of the
system; any disconnection of the mains must be performed on the mains-side of the
Inverter.
When connecting the line supply to the Inverter, make sure that the terminal case of the
motor is closed.
When changing from the ON to OFF-state of an operation if an LED or other similar display
is not lit or active; this does not indicate that the unit is switched-off or powered-down.
The inverter must always be grounded.
Isolate the line supply before making or changing connections to the unit.
Ensure that the inverter is configured for the correct supply voltage. The inverter must not
be connected to a higher voltage supply.
Static discharges on surfaces or interfaces that are not generally accessible (e.g. terminal
or connector pins) can cause malfunctions or defects. Therefore, when working with
inverters or inverter components, ESD protective measures should be observed.
Take particular notice of the general and regional installation and safety regulations
regarding work on dangerous voltage installations (e.g. EN 50178) as well as the relevant
regulations regarding the correct use of tools and personal protective equipment (PPE).

Caution
Children and the general public must be prevented from accessing or approaching the
equipment!
This equipment may only be used for the purpose specified by the manufacturer.
Unauthorized modifications and the use of spare parts and accessories that are not sold
or recommended by the manufacturer of the equipment can cause fires, electric shocks
and injuries.
Notice
Keep this manual within easy reach of the equipment and make it available to all users.
Whenever measuring or testing has to be performed on live equipment, the regulations
of Safety Code BGV A2 must be observed, in particular § 8 "Permissible Deviations
when Working on Live Parts". Suitable electronic tools should be used.
Before installing and commissioning, please read these safety instructions and warnings
carefully and all the warning labels attached to the equipment. Make sure that the
warning labels are kept in a legible condition and replace missing or damaged labels.
Transport and Warehousing
Warning
Correct transport, storage as well as careful operation and maintenance are essential for
the proper and safe operation of the equipment.
Caution
Protect the equipment against physical shocks and vibration during transport and storage.

Commissioning
Warning
Working on the equipment by unqualified personnel or failure to comply with warnings can
result in severe personal injury or serious damage to material. Only suitably qualified
personnel trained in the setup, installation, commissioning and operation of the product
should carry out work on the equipment.
Caution
Cable connection
The control cables must be laid separately from the power cables. Carry out the
connections as shown in the installation section in this manual, to prevent inductive and
capacitive interference from affecting the correct function of the system.
During Operation
Warning
The SINAMICS G120 inverters operate at high voltages.
When operating electrical devices, it is impossible to avoid applying hazardous voltages to
certain parts of the equipment.
Emergency Stop facilities according to EN 60204, IEC 204 (VDE 0113) must remain
operative in all operating modes of the control equipment. Any disengagement of the
Emergency Stop facility must not lead to an uncontrolled or an undefined restart of the
equipment.
Certain parameter settings may cause the SINAMICS G120 inverter to restart
automatically after an input power failure, for example, the automatic restart function.
Wherever faults occurring in the control equipment can lead to substantial material
damage or even grievous bodily injury (that is, potentially dangerous faults), additional
external precautions must be taken or facilities provided to ensure or enforce safe
operation, even when a fault occurs (e.g. independent limit switches, mechanical
interlocks, etc.).
Motor parameters must be accurately configured for motor overload protection to operate
correctly.
This equipment is capable of providing internal motor overload protection according to
UL508C.
Only Control Units with fail-safe functions can be used as an "Emergency Stop
Mechanism" (see EN 60204, section 9.2.5.4).
