Dimensioning

3 methods for dimensioning
Fast: Selection of the inverter based on the motor data of a 4-pole asynchronous motor.
Detailed: In order to optimise the selection of the inverter and all drive components, it is
worth to execute the detailed system dimensioning based on the physical requirements of the
application. For this purpose, Lenze provides the «Drive Solution Designer» (DSD) design pro-
gram.
Manual: The following chapter guides you step by step to the selection of a drive system.
