1) The typical power loss is at nominal load conditions and expected to be within
conditions).
Values are based on a typical motor efficiency (IE2/IE3 border line). Motors with lower efficiency add to the power loss in the frequency converter,
and motors with high efficiency reduce power loss.
Applies to dimensioning of frequency converter cooling. If the switching frequency is higher than the default setting, the power losses sometimes
rise. LCP and typical control card power consumptions are included. Further options and customer load sometimes add up to 30 W to the losses
(though typically only 4 W extra for a fully loaded control card or fieldbus).
For power loss data according to EN 50598-2, refer to www.danfoss.com/vltenergyefficiency.
2) Measured using 50 m (164 ft) shielded motor cables at rated load and rated frequency. For energy efficiency class, see chapter 9.4 Ambient
Conditions. For part load losses, see www.danfoss.com/vltenergyefficiency.

1) The frequency converter can run at -25% input voltage with reduced performance. The maximum output power of the
frequency converter is 75% if input voltage is -25%, and 85% if input voltage is -15%.
Full torque cannot be expected at mains voltage lower than 10% below the lowest rated supply voltage of the frequency
converter.
