Output voltages and frequencies of the 400V devices
1)
The voltage to the motor is dependent on the actual input voltage and the control method

).
2)
The output frequency is to be limited in such a way that it does not exceed 1/10 of the switching
frequency. Devices with higher max. output frequency are subject to export restrictions and are
only available on request.
3.2.2.1 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:

Open-loop drive converter with mains- and motor choke
at non-rigid supply system:
400 V mains voltage (100%) - 36 V reduced voltage (11 %)
= 356 V motor voltage
