Efficiency [%]
Table 6.5 Mains Supply 3x380–480 V AC Normal and High Overload: MH1, MH2, and MH3 Enclosure
1) NO: Normal overload, 110% for 1 minute. HO: High overload, 160% for 1 minute. H7K5: 150% for 1 minute.
A drive intended for HO requires a corresponding motor rating. For example, Table 6.5 shows that a 1.5 kW motor for HO requires a N2K2 drive.
2) Maximum cable cross-section is the largest cable cross-section that can be attached to the terminals. Always observe national and local
regulations.
3) Applies to dimensioning of drive cooling. If the switching frequency is higher than the default setting, the power losses may increase. LCP and
typical control card power consumptions are included. For power loss data according to EN 50598-2, refer to www.danfoss.com and search for
ecoSmart.
4) Efficiency measured at nominal current. For energy efficiency class, see chapter 6.5 Ambient Conditions. For part load losses, see
www.danfoss.com and search for ecoSmart.
5) Measured using 4 m (13.1 ft) shielded motor cables at rated load and rated frequency.
