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 adjustable frequency drive 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 consumption values 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 (+/-5%).
