American Wire Gauge.
3) Measured using 5 m screened motor cables at rated load and rated frequency.

The typical power loss is at nominal load conditions and expected to be within
cable conditions).
Values are based on a typical motor efficiency (eff2/eff3 border line). Motors with lower efficiency will also add to the power loss in the
frequency converter and opposite.
If the switching frequency is increased compared to the default setting, 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 typical 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 (

The three values for the max. cable cross section are for single core, flexible wire and flexible wire with sleeve, respectively.
