Overview

Examples of SINAMICS G120, frame size FSGX; with Power Module

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 technology with pulse-width modulation is used to achieve the highest degree of reliability and flexible motor operation. Comprehensive 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 number 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 produced by motors operating in generator mode connected to standard inverters to be fed back into the supply system. Additional cooling and additional space requirement in the control cabinet can be avoided as components such as braking resistors, 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 device. 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.

• as a universal drive in all industrial and commercial applications

• 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 inverters 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 functions. 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 versions 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 communication, 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 components, 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.

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 external) and are designed for drives without energy recovery capability. 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 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.

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 associated 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 u

>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 operation with output reactors or sine-wave filters, longer, shielded motor cables are possible and the motor service life can be extended:

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 currents, 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.

Technical specifications

Compliance with standards

CE mark

The SINAMICS G120 inverters meet the requirements of the Low-Voltage Directive 73/23/EEC.

Low-Voltage Directive

The inverters comply with the following standards listed in the official journal of the EU:

• EN 60204 Safety of Machinery, electrical equipment of machines

• EN 61800-5-1 Electrical power drive systems with variable speed – Part 5-1: Requirements regarding safety – electrical, thermal, and energy requirements

UL listing

Inverter devices in UL category NMMS certified to UL and cUL, in compliance with UL508C. UL list numbers E121068 and E192450.

For use in environments with pollution degree 2. Also see the Internet under http://www.ul.com

Machinery Directive

The inverters are suitable for installation in machines. Compliance with the Machinery Directive 98/37/EC requires a separate certificate of conformity. This must be provided by the plant construction 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 electric 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 conditions 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 Directive.

• 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 installed 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 values for conducted interference and radiated interference for the so-called “second environment” (= industrial power supply systems that do not supply households). These limit values are below the limit values of filter class A to EN 55011. Unfiltered 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 standards for electrical drive systems (PDS) of the range of standards 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 harmonics 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 harmonics, 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 complies with the EU EMC Directive. The EU EMC Directive is generally 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 ensure this.

SEMI F47

SEMI F47 is an industry standard relating to the immunity to voltage dips. This includes the requirement that industrial equipment 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, defined in accordance with SEMI F47-0706, these drives either continue to supply a defined output current, or using an automatic restart function, continue to operate as expected.

• 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.

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 integrated brake chopper to which an external braking resistor can be connected via terminals DCP/R1 and R2 (see DC link components).

PM240 Power Modules, frame size FSGX do not have an integrated 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 applications such as safe power-down after power failure or kinetic buffering (the DC link is supplied in the generator mode with the kinetic 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 connected (see load-side power components).

Line reactors are available to minimize line harmonics (see lineside 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 available both with and without integrated class A line filter. For compliance 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 integrated line filter can be connected to grounded (TN, TT) and non-grounded (IT) supply systems.
