Table 11: Output voltage and frequencies
1)
The voltage to the motor is dependent on the actual input voltage and the control method (=>
“Example 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. Units with higher max. output frequency are subject to export restrictions and are only
available on request.
DC switching level
DC switch-off level „Error! Underpotential“

UB_dc / V 780
DC switch-off level „Error! Overpotential“
UOP_dc / V 840
Table 12: DC switching level
1)
The DC switching level for the braking transistor is adjustable. The default value is the value spec-
ied in the table.
3.3.3.1 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
