Drive ratings
Three-phase supply voltage: 380…480 V 50/60 Hz
Three-phase motor 380...480 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 075N4 to D30N4 and 2.5 kHz for ATV71H D37N4 to D75N4).
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 14.
(2)Current on a line supply with the “Max. prospective line Isc” indicated and for a drive without any external options.
(3)Peak current on power-up for the max. voltage (480 V +10%).
(4)ATV71H 075N4 to D75N4 drives are available with or without a graphic display terminal. Catalog numbers for drives without a graphic
display terminal have the letter Z added at the end, e.g.: ATV71H075N4Z. This option is not available for drives operating in difficult
environmental conditions (5).
(5)Drives with the S337 or 337 extension are designed for use in difficult environmental conditions (class 3C2 in accordance with IEC 721-3-3).
They are supplied with a graphic display terminal.
(6)Drives with the extension 383 are intended for use with synchronous motors.
