This parameter defines the upper limit for the maximum power (see 2.29.1) and the maximum power at
derating end (see 2.29.3).

Depending on the module temperature (see 3.13 Module temperature) and the motor temperature (see 3.14
Motor temperature), the maximum power decreases based on the following curve. Each temperature can
have its own defined curve.
