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 drive. Applies for dimensioning of drive cooling. If the switching frequency is higher than the default
setting, the power losses can increase. LCP and typical control card power consumptions are included. For power loss data according to EN 50598-2, refer to www.danfoss.com/
vltenergyefficiency. 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.

9.2 Mains Supply

The unit is suitable for use on a circuit capable of delivering not more than 100 kA short circuit current rating (SCCR) at 480/600 V.

Mains voltage low/mains drop-out: During low mains voltage or a mains drop-out, the drive continues until the DC-link voltage drops below the minimum stop level, which
corresponds typically to 15% below the drive's lowest rated supply voltage. Power-up and full torque cannot be expected at mains voltage lower than 10% below the drive's lowest
rated supply voltage.

9.3.2 Torque Characteristics

The torque response time depends on application and load but as a rule, the torque step from 0 to reference is 4–5 x torque rise time.
