Typical power loss is at normal conditions and expected to be within ±15% (tolerance relates to variety in voltage and cable conditions.) These
1
values are based on a typical motor efficiency (IE/IE3 border line). Lower efficiency motors add to the power loss in the drive. Applies to dimension-
ing of drive cooling. If the switching frequency is higher than the default setting, the power losses can increase. LCP and typical control card power
consumptions are included. For power loss data according to EN 50598-2, refer to drives.danfoss.com/knowledge-center/energy-efficiency-direc-
tive/#/. Options and customer load can add up to 30 W to the losses, though usually a fully loaded control card and options for slots A and B each
add only 4 W.
Measured using 5 m (16.4 ft) shielded motor cables at rated load and rated frequency. Efficiency measured at nominal current. For energy efficiency

class, see the Ambient Conditions section. For part load losses, see drives.danfoss.com/knowledge-center/energy-efficiency-directive/#/.

If using an output filter, the output frequency is limited further. See the Motor Output (U, V, W) section.

10.2 Mains Supply

The unit is suitable for use on a circuit capable of delivering not more than 65 kA short circuit current rating (SCCR) at 480/600 V.

Mains voltage low/mains drop-out: During low mains voltage or a mains drop-out, the drive continues until the DC-link voltage drops below the
1
minimum stop level, which corresponds typically to 15% below the drive's lowest rated supply voltage. Power-up and full torque cannot be expec-
ted at mains voltage lower than 10% below the drive's lowest rated supply voltage.
Calculations based on UL/IEC 61800-3.
