SinaSave energy efficiency tool

Use SinaSave to calculate potential energy savings

The web-based tool SinaSave can be used to estimate the potential savings which can be achieved over the entire lifecycle, e.g. for pump and fan applications, thanks to SINAMICS. The tool takes into consideration all important plant-specific quantities, such as the power and load data of the application, the relevant control mode and the operation profile for the application in question. The result delivered by the tool specifies the potential energy savings which can be achieved with the specific application in conjunction with the Integrated Drive System or the drive component. The tool also provides a monetary evaluation of the potential savings and estimates the payback period.

Note:

The frequency converters on their own do not generally require identification according to the EMC Directive.

• 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

Machinery directive

The converters are suitable for installation in machines. Compliance with the Machinery Directive 2006/42/EC requires a separate certificate of conformity. This must be provided by the plant construction company or the organization marketing the machine.

Functional safety

SINAMICS G120P are not intended for use in installations with functional safety as defined by ISO 13849‑1, IEC 61508‑x.

EMC Directive

• EN 61800‑3
  Variable-speed electric drives
  Part 3: EMC product standard including specific test methods

The following explanatory information applies to SINAMICS G120P converters supplied by Siemens AG:

• The EMC product standard EN 61800-3 does not apply directly to a converter but to a PDS (Power Drive System), which comprises the complete circuitry, motor and cables in addition to the converter.
• Converters are normally only supplied to experts for installation in machines or systems. A converter must, therefore, only be considered as a component which, on its own, is not subject to the EMC product standard EN 61800-3. The converter's operating instructions, however, specifies the conditions regarding compliance with the product standard if the converter 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 converters on their own do not generally require identification according to the EMC Directive.
• 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 created.
• The EMC product standard EN 61800‑3 also defines limit values for conducted interference and radiated interference for the "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 converters 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 G120P, 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 converters. Since converters 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. EN 61000‑2‑4 applies for devices >75 A.
• Regardless of the configuration with SINAMICS G120P 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. EN 61000‑x‑x) can be used instead. It is important that the conducted and emitted interference at the line supply 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.

All Power Modules of the SINAMICS G120P product family fulfill the latest standard SEMI F47-0706 ¹⁾. 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.

¹⁾ SEMI F47 for PM330 Power Modules, frame sizes HX (500 V to 690 V) and JX, available soon

EAC approval for Russia/Belarus/Kazakhstan/Armenia

Since 2013-02-15, Russia, Kazakhstan, Belarus and Armenia have been united in the Eurasian EAC customs union. An EAC approval as replacement for the GOST mark is required for all products that are to be sold in Russia.

All devices delivered to the customs union must have these customs certifications.

RCM approval for Australia

The RCM mark is required for marketing Siemens electronic devices in Australia. Electronic devices must provide proof of EMC clearance in Australia, similar to the CE marking of conformity laid down by the EMC directive applicable in the EU. The converters must be marked accordingly. These requirements have been in force since October 1, 1999.

On March 1, 2016, the C-Tick mark was replaced by the RCM mark.

KC approval for South Korea

KC approval (formerly KCC) is required for the distribution of our electrical equipment in South Korea. Electronic devices that are covered by the EU Directive on Electromagnetic Compatibility must provide an EMC certificate issued by a resident authority in South Korea. The converters must be marked accordingly. This requirement has been in force since January 24, 2011.
