Applies for 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 Danfoss
website.

Efficiency measured at nominal current. For energy efficiency class, see chapter Surroundings. For part load losses, see Danfoss
website.
