Danfoss VLT AutomationDrive FC 300 Design Guide

If the switching frequency is raised from nominal, the power losses rise significantly. LCP and typical control card power consumptions are
included. 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.
4) Measured using 16.5 ft. [5 m] shielded motor cables at rated load and rated frequency.

1) American Wire Gauge.
2) For fuse ratings, see chapter 7.2.1 Fuses.
3) Typical power loss is at normal conditions and expected to be within ± 15% (tolerance relates to variety in voltage and cable conditions.) These
values are based on a typical motor efficiency (IE/IE3 border line). Lower efficiency motors add to the power loss in the adjustable frequency drive.
If the switching frequency is raised from nominal, the power losses rise significantly. LCP and typical control card power consumptions are
included. 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.
