9.7.1 Derating factors

The derating factors shown below are applied to the rated DC output by the user.
They are not automatically implemented by the drive.

If not all of the derating factors are considered, this could result in a drive overtempera-
ture condition.
The specific alarm indicates this condition and normal drive operation is stopped.

: Derating factor for mains voltage from 460V
ply from AFE200.
: Derating factor for 50°C ambient temperature (1 % each °C above 40°C)
: Derating factor for installation at altitudes above 1000 meters a.s.l.. Value

to be applied at each 100 m increase above 1000 m (up to a maximum of
4000 m).
I.e.: Altitude 2000 m, K
((12*100)/100) = 88 % I
: Derating factor for higher switching frequency
