3.3 Unit data
3.3.1 Overview
The technical data are for 2/4-pole standard motors. With other pole numbers the drive
converter must be dimensioned onto the motor rated current. Contact KEB for special or
medium frequency motors.

Table 8: Overview unit data
1)
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.
2)
The values refer in % to the rated output current IN.
3.3.2 Rated operation
All rated values refer to a rated operation at UN = 400 V
, rated switching frequency fSN and
an output frequency fout = 50 Hz.
