4.2.5 Information on the motor–converter selection IM control digital
Two inverter clock frequencies can be parameterized: 4 kHz and 8 kHz.
Please observe the current de–rating at 8 kHz.
Table 4-9
Dimensioning the series reactor, refer to Section 4.2.2
Heatsink tempera-
The individual power modules have different heatsink response temperatures.
Range, approx. 80 °C to 100 °C at the measuring point.

Current de–rating
All of the specified load currents are valid up to an installation altitude of
