Table 8: Technical data 400V class
1) The values refer percentage to the output rated current IN.
2) The values resulting from rated operation with B6 rectier circuit and mains choke 4% UK.
3) The output frequency is to be limited in such a way that it does not exceed 1/10 of the switching frequency.
4) Rated operation corresponds to U
N = 400 V; fSN; fA = 50 Hz (typically value).
5) On reaching the temperature Tdr the switching frequency is step down. The switching frequency is increased again on cooling down
to temperature Tur.
6) The voltage at the motor is dependent on the series-connected units and on the control method
, see „Calculation of the motor voltage“.
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.
