Form 1003
From this curve, the follow result
 A max. power value depending on the module temperature (Pmax_TModul)
 A max. power value depending on the motor temperature (Pmax_TMotor)
The power is limited to the smaller of the two Pmax_TModul and Pmax_TMotor values.

P max DE....... Maximum power at derating end
Ref. Uz ........ Reference variable DC-link voltage (see 2.43 Reference value of DC-link voltage).
Ref. Iz .......... DC-link current reference variable (see 2.44 Reference value of DC-link current)
TModul DS ...... Module temperature at start of derating
TModul DE ...... Module temperature at end of derating
TMotor DS ....... Motor temperature at start of derating
TMotor DE ....... Motor temperature at end of derating
The MSB is of no relevance for any of these!
The values "Maximum power" and "Maximum power for temperature derating end" are the same for both
curves.
For temperatures below the value defined in TModul DS or TMotor DS, maximum power corresponds to the
value of P max.
For temperatures above the value defined in TModul DE or TMotor DE, maximum power corresponds to the
value of P max DE.
In between, the maximum power changes linearly between the values of P max and P max_DE.
(see diagram above).
Limitation:
If T DS ≥ T DE, T DS is limited to T DE
If P max DE > P
max
or P
max zul
, P max DE is limited to P
max
or P
max zul
