Siemens presents the new Sinamics V20 inverter for basic applications

With its Sinamics V20 inverter, the Siemens Drive Technologies Division presents a new single-axis drive for basic applications. The compact and rugged inverter excels with short commissioning times, straightforward operation and high cost-effectiveness. The Sinamics V20 comes in four sizes to cover the performance range from 0.12 to 15 kW and is used to operate pumps, fans, compressors and conveyor systems, as well as for simple drive tasks in the processing and handling industry.

Simple drive tasks demand straightforward, cost-effective solutions. It is against this background that Siemens is expanding its Sinamics portfolio to include a new single-axis Sinamics V20 inverter in four sizes that covers a performance range from 0.12 to 15 kW. The compact inverters can be connected directly in line, or alternatively mounted as a push-through installation in addition to the conventional wall-mounting method. Since no further modules or add-on options are required for operation, the installation time is reduced to a minimum. The integrated Basic Operator Panel (BOP) enables trouble-free on-site commissioning and operation. Besides the universal serial interfaces for easy connection to Simatic controllers, the terminal also incorporates a Modbus interface for communication with third-party controls. Pre-built connection and application macros are facilitating application-specific settings. As for units with power rating higher than 7.5 kW the brake resistor can be connected directly to the already integrated brake chopper. 

Easy to use

Operation of the new Siemens inverter is just as easy as its commissioning. In this way, parameters that have been optimized for one application can easily be transferred to other units. SD or MMC cards may be used to save user data either via the BOP interface or the battery-operated Parameter Loader – even without power supply of the inverter – and to load them again as required. The current firmware can also be loaded. Tailored interconnection and application macros (also for pumps, fans and compressors) provide the right settings for the particular application. The 'Keep Running Mode' also automatically adapts the Sinamics V20 to the power supply conditions to achieve higher availability when it is operated on unstable networks. Here, line fluctuations are compensated internally or error messages are acknowledged autonomously. Due to the enhanced cooling concept and coated PCBs and electronic components, the Sinamics V20 is extremely rugged, both electrically and mechanically, making the unit a reliable drive even in harsh environments. 

Energy efficiency and cost efficiency are top assets

The demand-driven regulation of the motor speed also provides high energy savings even for basic applications. The Sinamics V20 is equipped with an energy-optimized control mode (ECO Mode) for increased energy efficiency, which automatically adapts the magnetic flux in the motor to the prevailing operating point. Furthermore, the DC link coupling enables efficient energy utilization of two inverters in a grouped system. The Sinamics V20 can also be set to hibernation mode, which prolongs the service life of the motor and also reduces wear (of pumps, for example). The current energy consumption in the display means that the operator always has the energy efficiency and cost efficiency of the drive in focus.
