Efficiency
For fuse ratings, see 8.3.1 Fuses
1) High overload = 160% torque during 60 sec., Normal overload = 110% torque during 60 sec.
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% (tolerence relates to variety in voltage and
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 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 inaccuracy must be allowed for (+/-5%).
5) The three values for the max. cable cross section are for single core, flexible wire and flexible wire with sleeve, respectively.
