VM_SWITCHING_FREQUENCY[MAX] = Power stage dependent
VM_SWITCHING_FREQUENCY[MIN] = 0
This variable maximum is used by the Minimum Switching Frequency (05.038) to define the minimum frequency limit
used if the inverter thermal model is actively reducing the switching frequency due to temperature.
Definition
Note that parameter Maximum Switching Frequency (05.018) takes priority over parameter Minimum Switching
Frequency (05.038) so is not limited by parameter Minimum Switching Frequency (05.038). The actual minimum
switching frequency limit used is the lower of Maximum Switching Frequency (05.018) and Minimum Switching
Frequency (05.038).
