Table 8: Technical data 400V class
1) The values refer percentage to the rated output current I
N
.
2) The values resulting from rated operation with B6 rectifier circuit and mains choke 4% U
K.
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

; f
out
= 50 Hz (typically value).
5) On reaching the temperature T
dr
the switching frequency is step down. The switching frequency is increased again on cooling down
to temperature T
ur
.
6) The voltage at the motor is dependent on the series-connected units and on the control method , => „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 rated motor current. Contact
KEB for special or medium frequency motors.
