Measured using 5 m screened motor cables at rated load and rated frequency
4.
The typical power loss is at normal load conditions and expected to be /- 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 cus-
tomer load may add up to 30W to the losses. (Though typically only 4W 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%).
