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