Sinamics G120C Converter Series by Siemens with New Frame Sizes to Address Higher Power Ratings

Characteristic features of the series include a compact design with optional filter, long cable lengths as standard, full integration into the Totally Integrated Automation (TIA) Portal and simple control and commissioning. The “Safe Torque Off” function (STO) integrated as standard prevents a motor from unintentionally starting.

Siemens has added three new enclosure sizes to its Sinamics G120C series: FSD (22 to 45 kW), FSE (55 kW) and FSF (75 to 132 kW) – allowing it to offer this compact series for applications demanding higher power ratings. The Sinamics G120C – with its total of seven different frame sizes for operation on three-phase line supplies – features a particularly compact design, as components such as the DC choke and EMC filter are already integrated in the device. This reduces the space required in the control cabinet. The design of the converters also allows all of the frame sizes to be lined up next to one another without any derating.

The parameter settings of the Sinamics G120C can be simply copied to an SD memory card and thus transferred to other devices. This allows drives to be reliably cloned without additional technical support and facilitates series commissioning with minimum associated costs. Sinamics G120C converters can also be integrated into the TIA Portal system diagnostics and can communicate with Simatic controllers via Profinet and Profibus. This means that the control and drive system can be intuitively programmed. The TIA Portal library concept ensures that converters can be easily reused, including their parameters and hardware components. The energy-efficient sensor-less vector control permits high torque levels to be achieved at low speeds.

The Sinamics G120C converters are suitable for applications such as conveyor belts, mixers, extruders, pumps, fans, compressors and simple handling machines.
