Table 8: Overview of the 400V unit data
1) The values refer in % to the output rated current I
N
.
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.
3) Rated operation corresponds U
N_ac
= 230V, , rated switching frequency, output frequency = 50 Hz.
4) On reaching the temperature Tdr the switching frequency is step down. . The switching frequency
is increased again on cooling down to temperature Tur.
5) The voltage at the motor is dependent on the series-connected units and on the control method
