Table 8.15 Derating Tables for Frequency Converters Rated 525–690 V (T7)
8.5.3 Automatic Adaptations to Ensure
Performance
The frequency converter constantly checks for critical levels
of internal temperature, load current, high voltage on the
intermediate circuit and low motor speeds. As a response
to a critical level, the frequency converter can adjust the
switching frequency and/or change the switching pattern
in order to ensure the performance of the frequency
converter. The capability to automatically reduce the
output current extends the acceptable operating
conditions even further.
8.5.4 Derating for Low Air Pressure
The cooling capability of air is decreased at lower air
pressure.
Below 1000 m altitude, no derating is necessary but above
1000 m the ambient temperature (T
AMB
) or max. output
current (I
out
) should be derated in accordance with
Illustration 8.3.
