1) The voltage to the motor is dependent on the actual input voltage and the control method (=>
„Example of the calculation of the possible motor voltage").
2) The output frequency is to be limited in such a way that it does not exceed 1/10 of the switching
frequency. Units with higher max. output frequency are subject to export restrictions and are only
available on request.
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:

Drive converter open-loop
Drive converter closed-loop
Motor choke U
