Drive controller derating

The maximum permissible output current for PDCs of performance class 1000 W must be
reduced as follows depending on the installation altitude, mounting position and ambient
temperature.
The derating relates to the rated current of the power unit. The maximum current from the
power unit may be taken at an average speed of > 10 Hz (corresponds to the rotating field
frequency > 10 Hz for EC motors over a period of 20 s). At frequencies < 10 Hz, the maximum
permissible current corresponds to the rated current of the power unit.
Derating as a function of the installation altitude
For all permissible mounting types, starting from an installation altitude of 1000 m, a derating
of 10% current per additional 1000 m elevation gain applies. In this case, the motor current and
the output current of the digital outputs must be reduced.
All other functions do not have to be reduced up to the maximum installation altitude.
The figure below shows the maximum permitted output current as a function of installation
altitude for the derating.
