For steady−state operation in generator mode with increased DC−bus voltage or supply
from a closed−loop DC−voltage source, interpolate accordingly between the values given in
the table.
The increased rated currents are valid for the entire voltage range specified at switching
frequencies of 4 kHz and 8 kHz.
 Note!
If in this connection a heatsink temperature of > 70 °C is reached, the drive
switches to a switching frequency of 4 kHz, independently of the selected
switching frequency.
