Siemens launches SinamicsV20 VFD (Variable-frequency Drive) suitable for basic applications

Siemens today launched a new stand-alone VFD (Variable-frequency Drive) for basic applications in China, the Sinamics V20. The VFD (Variable-frequency Drive) was jointly designed and developed by Siemens engineers from China, Germany and the UK, and was produced at Siemens CNC (Nanjing) Co., Ltd. This VFD (Variable-frequency Drive) is compact, durable, quick to debug, easy to operate and economical and practical. Pei Anzi, vice president of the drive technology group and general manager of the motion control department of Siemens (China) Co., Ltd., said: "The new VFD (Variable-frequency Drive) Sinamics V20 launched this time is Siemens' application of global technology systems to local products. The best example of design. Siemens has always been based on the needs of the Chinese market, and continues to design products and solutions that suit local needs."

Simple transmission tasks require convenient and cost-effective solutions. Sinamics V20VFD (Variable-frequency Drive) has two power supply methods, a total of four dimensions, and the power range covers 0.12kW to 15kW. It is suitable for driving pumps, fans, compressors or conveyor systems, as well as in the field of processing and transportation. Simple task. This compact VFD (Variable-frequency Drive) can be installed side by side to save installation space. In addition to the conventional cabinet wall installation, it can also be installed through the wall. Significantly reduces installation time as it operates without additional modules or additional options. The integrated operator panel (BOP) enables smooth on-site commissioning and operation. In addition to a universal serial interface for easy connection to controllers, the terminal also has a universal language Modbus interface applied to electronic controllers, which can be used to communicate with third-party controllers. Prefabricated interfaces and application macros (that is, organizing a set of commands to complete a specific task) facilitate application-oriented settings. For VFD (Variable-frequency Drive) with rated power higher than 7.5kW, this VFD (Variable-frequency Drive) can directly connect the braking resistor with the integrated braking chopper.

easy to use

The operation of Sinamics V20VFD (Variable-frequency Drive) is as convenient as debugging. Users can easily transfer the parameters optimized for a certain application to other VFD (Variable-frequency Drive). Data can be saved using SD or MMC card and via BOP interface or battery powered parameter loader (VFD (Variable-frequency Drive) can also operate without mains power) and loaded on demand. It is also possible to load the latest firmware. Predefined connection and application macros (available for pumps, fans, compressors, conveyors, etc.) provide correct and easy settings for specific applications. The Sinamics V20's "keep running mode" auto-tuning feature allows the product to adapt to power conditions in order to keep running well on unstable grids. Fluctuations in the input power are compensated within the device and error messages are automatically recognized. Thanks to the enhanced cooling design and equipped with coated PCB and high-reliability electronic components, Sinamics V20 is extremely durable both electrically and mechanically, and its performance is reliable even under harsh environmental conditions.

Energy saving and cost-effectiveness are the biggest assets

High energy savings can be achieved even for basic applications, since the motor speed can be adjusted according to demand. The Sinamics V20 has an energy-optimized control mode (ECO mode) that can be used to increase energy efficiency by automatically adapting the magnetic flux in the motor to the prevailing operating point. Moreover, through DC link coupling, two VFDs (Variable-frequency Drives) in a packet system can be used in an energy-sharing manner. The Sinamics V20 has a sleep mode to extend the operating life of the motor and reduce wear (e.g. of the pump). The current power consumption can be shown on the display, so that the operator can always easily understand the energy efficiency and economic benefits of the VFD (Variable-frequency Drive).

The launch of Sinamics V20 confirms Siemens' commitment to increase localization investment in recent years. Siemens' strategy of localizing the entire industrial chain is to realize the localization of product life cycle management, supply chain management and customer management, so as to design, develop and manufacture more products that are closer to the needs of Chinese customers, so as to improve the competitiveness of China's manufacturing industry.
