Danfoss VLT AutomationDrive FC 300 Series Installation Manual

1) For type of fuse, see chapter 8.4.1 Fuses.
2) American wire gauge.
3) Measured using 16.5 ft. [5 m] shielded motor cables at rated load and rated frequency.
4) The typical power loss is at nominal load conditions and expected to be within ±15% (tolerance relates to
variances in voltage and cable conditions). Values are based on a typical motor eciency (IE2/IE3 border line).
Motors with lower eciency will also add to the power loss in the adjustable frequency drive and vice-versa. If the
switching frequency is increased to the default setting, the power losses may rise signicantly. LCP and typical
control card power consumptions are included. Further options and customer load may add up to 30 W to the
losses. (Though typical only 4 W extra for a fully loaded control card, or options for slot A or slot B, each).
Although measurements are made with state-of-the-art equipment, some measurement inaccuracy must be
allowed for (±5%).
8.1.2 Derating for Temperature
The frequency converter automatically derates the
switching frequency, switching type, or output current
under certain load or ambient conditions as described in
the following. Figure 8.1 to Figure 8.8 show the derating
curve for SFAWM and 60 AVM switching modes.
