Siemens' Sinamics V20 inverter covers a performance range from 1/6-20 hp
Siemens' single-axis Sinamics V20 inverter comes in four frame sizes, covering the performance range from 1/6–20 hp. The inverter can be connected directly in-line and mounted as a push-through installation in addition to the conventional wall-mounting method.
Additionally, the integrated Basic Operator Panel (BOP) enables on-site commissioning and operation. Besides the universal serial interfaces that allow for connection to Simatic PLC controllers, a Modbus interface is also included for communication with third-party controls. Pre-built connection and application macros are used for facilitating application-specific settings. For units with power ratings higher than 10 hp, a braking resistor can be connected directly to integrated braking chopper.
Tailored inter-connectivity and application macros (i.e. for pumps, fans and compressors) provide the correct settings for the particular application. The Keep Running Mode automatically adapts the Sinamics V20 inverter to the power supply to achieve higher availability when operated on unstable networks. In this mode, line fluctuations are compensated for internally and error messages are acknowledged autonomously.
The Sinamics V20 is equipped with an energy-optimized control mode (ECO-mode) for increased energy efficiency. ECO-mode automatically adapts the magnetic flux in the motor to the optimum operating point. In addition, the DC link coupling enables efficient energy utilization of inverters grouped together. Further, the Sinamics V20 can be set to hibernation mode, which prolongs the service life of the motor and also reduces system component wear (i.e. pumps). Additionally, by displaying real-time energy consumption on the operator panel display, the operator always has the drive’s energy and cost efficiencies in focus at all times.
