1)
The voltage to the motor is dependent on the actual input voltage and the control method (=> „3.4.3.1 Ex-
ample for the calculation of the 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.
Devices with higher max. output frequency are subject to export restrictions and are only available on request.

The DC switching level for the braking transistor is adjustable. The default value is the value specied in the table.
3.4.3.1 Example for the calculation of the motor voltage
The motor voltage for dimensioning of the drive is depending on the used components.
The mains voltage reduces according to the following table:
Components Reduction / % Example:
Mains choke U
k 4
Closed-loop drive controller with mains and motor choke
at non-rigid supply system:
400 V mains voltage - 15 % = 340 V motor voltage
Drive controller open-loop 4
Drive controller closed-loop 8
Motor choke U
