SINAMICS G180 The LOHER DYNAVERT T frequency converter integrated as SINAMICS G180 into the SINAMICS range has been deployed for over forty years for applications where maximum reliability and availability of the drive are of paramount importance. SINAMICS G180 thus benefits from the many years of expertise acquired by LOHER Motors & Drives in the manufacture of motors and converters to the extent that the frequency converters are always systematically developed to take into account the requirements of the drive system as a whole. SINAMICS G180 converters can be supplied for standard voltages 400, 500 and 690 V in the output range up to 6.6 MW. They are available as a compact unit, a cabinet system or a cabinet unit, with air or liquid cooling, for operation with synchronous and induction motors. A wide range of add-on electrical components allow the drive system to be optimized for specific requirements. Configuring is greatly simplified by predefined interfaces and commissioning is speeded up by the preassignment of parameter settings at the factory. The accuracy of the sensorless vector control makes the converter an ideal partner for many types of drives, such as those used for pumps, fans, centrifuges, presses, extruders or compressors, and an additional actual speed value encoder is therefore superfluous. Appropriate encoder evaluation units are available for the SINAMICS G180 converters so that they can address applications that require an encoder for plant-specific reasons. The SINAMICS G180 can be flexibly integrated into any automation concept whether it employs a conventional control or a bus system. Apart from the standard converter interface (compliant with NAMUR NE37), the following can also be supplied as options to provide communication with the supervisory control system: PROFIBUS DP Modbus RTU Modbus TCP CANopen Ethernet (PROFIBUS DP with Ethernet-PROFIBUS converter) Optionally available peripheral boards can be selected to add the following inputs/outputs to the converter: Digital and analog inputs and outputs 2 PTC thermistor inputs for ATEX-certified motor temperature monitoring for motors in hazardous zones (prewarning/trip) Benefits The converters are exceptionally quiet and compact thanks to state-of-the-art IGBT power semiconductors and an innovative cooling concept. The clock frequency is optimized to reduce system losses to a minimum. The “random pattern” function significantly reduces motor noise. Plant and system availability are increased by being able to quickly and simply replace power components. Essential spare parts can be requested at any time for any individual converter by means of the “SparesOnWeb” Internet tool. Optimized use of components reduces cabinet dimensions to a minimum. Easy integration into automation solutions via analog and digital interfaces. Number of interfaces can also be expanded through installation of an optional peripheral board. Data are transmitted over popular bus systems (PROFIBUS DP, CANopen, Modbus RTU or Modbus TCP) Fast, easy commissioning and parameterization using interactive menus on an operator panel with illuminated graphic LCD and plain-text display, or PC-supported using the IMS commissioning tool (Inverter Management Software). The entire production process is required to meet stringent quality standards and subject to extensive controls, thereby ensuring a high degree of functional reliability during installation, commissioning and operation. Application The SINAMICS G180 is especially suited to applications in industries such as the chemical industry oil and gas industry power plant and utilities industries plastics industry process industry primary industry test bench systems conveyor systems and for general mechanical engineering applications. Design Platform concept All of the SINAMICS G180 versions are consistently based on an integrated, standardized, common, modular platform concept. Shared hardware and software components, as well as standardized tools for dimensioning, configuring and commissioning tasks ensure a high level of integration between all components. All devices – from the lowest rating class in compact unit form to the largest version in the form of an air-cooled or liquid-cooled cabinet unit – have the same features with a virtually identical scope of functions. All frequency converters in the SINAMICS G180 range operate with the Control Board. All Control Boards utilize the same firmware and all are operated via the Inverter Management Software IMS. Both the IMS and the firmware can be upgraded and downgraded as required to facilitate communication.

SINAMICS G150 Drive converter cabinet units
SINAMICS G150 Drive converter cabinet units SINAMICS G150 converter cabinet units, versions A and C With its SINAMICS G150 converter cabinet units, a drive system is available on which all line-side and motor-side components are integrated together with the Power Module extremely compact into a specially designed cabinet enclosure. This approach minimizes the effort and expense required to configure and install them. SINAMICS G150 has been specially designed to meet the requirements of drives with square-wave and constant load characteristics, with medium performance requirements, and without regenerative feedback capability. The control accuracy of the sensorless vector control is suitable for most applications, which means that an additional actual speed value encoder is not required. SINAMICS G150 converter cabinet units are optionally available with an encoder evaluation function in order to handle applications that require an encoder for plant-specific reasons. SINAMICS G150 converter cabinet units offer an economic drive solution that can be adapted to customer-specific requirements through a wide range of components and options. SINAMICS G150 is available in two versions: Version A All optionally available line connection components, such as the main switch, circuit breakers, line contactor, line fuses, line filter or motor-side components and additional monitoring devices, can be installed as required. This version is also available with power units connected in parallel. Version C Offers an extremely space-optimized structure without line-side components. This particularly slimline version can be used, for example, when line connection components are accommodated in a central low-voltage distribution panel (MCC) in the plant. Benefits Particularly quiet and compact converters thanks to state-of-the-art IGBT power semiconductors and an innovative cooling concept. Individual modules and power components can be replaced quickly and easily, which ensures a higher level of plant availability. Replaceable components have been designed so that they can be quickly and easily replaced. In addition, the “Spares On Web” Internet tool makes it easy to view the spare parts that are available for the particular order at all times. Can be easily integrated in automation solutions by means of a standard communications interface as well as a range of analog and digital interfaces. Easy commissioning and parameterization using interactive menus on the AOP30 Advanced Operator Panel with graphic LCD and plain-text display, or PC-supported using the STARTER commissioning tool (see Chapter Tools and configuration). Preset software functions make it easier to adapt the converter to the individual plant. For example, the key functions for controlling pumps are stored as a preprogrammed macro in the drive. With regard to EMC, the devices are subdivided into various zones, and as a consequence, they are extremely insensitive to disturbances and are very reliable in operation. With the help of simulated conditions, partitions have been designed to act as air guides and to help dissipate heat. Special measures used in the construction of the cabinets ensure that they remain mechanically durable over their entire life cycle. All components, from individual parts to the ready-to-connect cabinet, undergo rigorous testing throughout the entire production process. This guarantees a high level of functional reliability during installation and commissioning, as well as in operation. Application Variable-speed drives are ideal for all applications that involve moving, conveying, pumping or compressing solids, liquids or gases. Key applications include: Pumps and fans Compressors Extruders and mixers Mills
