Power losses and efficiency
Estimated power loss at rated maximum load [W]
(1)
1
The typical power loss is at normal load conditions and expected to be within ±15% (tolerance relates to variety in voltage and cable conditions).
Values are based on a typical motor efficiency. Lower efficiency motors also add to the power loss in the drive and conversely. If the switching fre-
quency is raised from nominal, the power losses may rise significantly. LCP and typical control card power consumptions are included. Further op-
tions and customer load may add up to 30 W to the losses. (Though typically 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%).
