Single-axis ac drive
Siemens’ single-axis Sinamics V20 ac drive, frame size E, with both low overload (LO) and high overload (HO) ratings, features easy setup and operation with high energy efficiency. With a power rating ranging from 1/6 to 40 hp at 480 Vac, Sinamics V20 drives are available in five frame sizes and are ideal for material handling, conveyor, pump, fan, and compressor applications. Pre-built connection and application macros are used for facilitating application-specific settings. Parameters that have been optimized for one application can easily be transferred to other drive units using SD cards via the basic operator panel or the battery-operated parameter loader. Tailored inter-connectivity and application macros (i.e. for pumps, fans, and compressors) provide the correct settings for the particular application. The demand-driven regulation of the motor speed also provides increased energy savings even for many applications. 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. The dc link coupling enables efficient energy use of drives grouped together. The Sinamics V20 can also be set to hibernation mode.
