3.3.2.1 Example of the calculation of the possible motor voltage:
The motor voltage for dimensioning of the drive is depending on the used components.
The motor voltage reduces according to the following table:

Example:
open-loop drive converter with mains- and motor choke at
non-rigid supply system:
400 V mains voltage - 11 % = 356 V motor voltage
