Drive converter cabinet units

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.
  • 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.

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
