The power available from a rectifier may limit these figures.
The drive will automatically reduce the output switching frequency so that the highest possible output current can be supported without a thermal trip.
This allows the drive to support the highest possible current at standstill while operating at a higher switching frequency under normal running
conditions.
This feature can be disabled using drive Pr

, see the
Advanced User Guide
