Drive ratings
Three-phase supply voltage: 500…690 V 50/60 Hz
Three-phase motor 500...690 V
(1)These power ratings and currents are given for an ambient temperature of 50°C (122°F) at the factory-set switching frequency, used in
continuous operation (factory-set switching frequency of 4 kHz for ATV71H U22Y to D30Y and 2.5 kHz for ATV71H D37Y to D90Y).
Above this factory setting, the drive will reduce the switching frequency automatically in the event of excessive temperature rise.
For
continuous operation above the factory setting, derating must be applied to the nominal drive current in accordance with the
curves
on page 15.
(2)Current on a line supply with the “Max. prospective line Isc” indicated and for a drive without any external options.
Note:
The maximum transient current for 60 s corresponds to 150% of the maximum nominal current In.
The maximum transient current for 2 s corresponds to 165% of the maximum nominal current In.
