Measured using 5 m screened motor cables at rated load and rated

The typical power loss is at normal load conditions and expected
to be within
±
15% (tolerance relates to variety in voltage and cable
conditions).
Values are based on a typical motor efficiency (eff2/eff3 border line).
Lower efficiency motors will also add to the power loss in the
frequency converter and vice versa.
If the switching frequency is raised from nominal the power losses
may rise significantly.
LCP and typical control card power consumptions are included.
Further options and customer load may add up to 30 W to the
losses. (Though typically 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%).
