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.

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 I
