When the given frequency is less than the lower limit one that setting though F0.07, the
frequency inverter operate to zero frequency. But
we should keep certain output voltage

When the output frequency of frequency inverter is 0Hz and the vector or VF control has
torque boost, the frequencyinverter has certain voltage output with long working to zero
