A wide range of add-on electrical components allow the drive system to be optimized for specific requirements. Configuration and commissioning are greatly simplified by predefined interfaces.
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.
However, encoder evaluation units are available for the SINAMICS G130 converters so that they can address applications that require an encoder for plant-specific reasons.
Communication between the Control Unit, the Power Module and other active SINAMICS components is performed via DRIVE-CLiQ, the drive's internal interface. The DRIVE-CLiQ connections, which are available as pre-assembled cables of different lengths, allow a complete converter system to be put together quickly.
For communication with the process control system, with the CU320‑2 Control Unit either a PROFIBUS or a PROFINET interface is available as standard. The interface can also be expanded with digital and analog inputs and outputs. The TM31 Terminal Module and TB30 Terminal Board are provided for this purpose. Additional expansion cards can also be installed to allow communication via CANopen or EtherNet/IP.
- Particularly quiet and compact converters due to the use of 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 (http://www.siemens.com/sow).
- Easily integration in automation solutions by means of a standard communications interface as well as a range of analog and digital interfaces.
- Simple 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 (http://www.siemens.com/starter).
- Preset software functions make it easier to adapt the converter to the individual plant.
- 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.
