The Sizer software from Siemens is an engineering tool for planning drive applications with Sinamics. With the new version Sizer 3.4, two drive solutions can now be compared with regard to their energy efficiency, enabling the savings potential to be determined. A conversion function makes it easy to modify drive configurations that have already been engineered and then to determine the effects on energy consumption so that the best variant can be selected. The energy analysis takes into account components such as the motor, power module, converter, line reactor, input reactor and output reactor as well as active interface modules. For the energy needs of the mechanical system the power required at the device is taken into account.
