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 dimension-

ing 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. 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.

Measured using 5 m (16.4 ft) shielded motor cables at rated load and rated frequency. Efficiency measured at nominal current.
