3) Measured using 16.4 ft. [5 m] shielded motor cables at rated load and rated frequency.
4) The typical power loss is at n om inal load conditions and expecte d to be wi
thin +/-15%
(tolerance relates to variety in voltage and cable conditions).
Values are based on a typical motor efficiency (eff2/eff3 border line). Less efficient mo tors will
also add to the power loss in the adjustable frequency d rive and vice
versa.
If the switching frequency is raised from nominal, the power losses may rise significantly.
LCP and typical control card power consumption values are included. Further options and
customer load may add up to 30 W to the loss es. (Though typical, only 4

Although measurem e n ts are made with state of the art equipment, som e measurement
inaccuracy must be allowed for (+/-5% ).
