Efficiency
1) For type of fuse see section Fuses.
2) American Wire Gauge.
3) Measured using 5 m screened motor cables at rated load and rated frequency.
4) The typical power loss is at nominal load conditions and expected to be within +/-15% (tol-
erence relates to variety in voltage and cable conditions).
Values are based on a typical motor efficiency (eff2/eff3 border line). Lower efficient motors will
also add to the power loss in the frequency converter and opposite.
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 30W to the losses. (Though typical 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 inaccur-
acy must be allowed for (+/-5%).
