The typical power loss is at nominal load conditions and expected to be within ±15% (tolerance relates to variety in voltage and cable conditions).
1
Values are based on a typical motor efficiency (IE2/IE3 border line). Motors with lower efficiency add to the power loss in the drive, and motors with
high efficiency reduce power loss. Applies to dimensioning of drive 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

Measured using 50 m (164 ft) shielded motor cables at rated load and rated frequency. For energy efficiency class, see chapter Ambient Conditions.

The drive can run at -25% input voltage with reduced performance. The maximum output power of the drive 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 drive.
