Note
For the MSD–SRM operating mode (high–speed MSD synchronous
applications), inverter pulse frequencies are set that differ from the rated
frequencies. This consequently ensures an optimum ratio between the inverter
pulse frequency and the output frequency.
The derating resulting from this should be taken into account when selecting
the power module.
The frequencies relevant when engineering the system should be appropriately
taken from the following documentation.
