frequency
The following assumes
frequency is set as the rated frequency.
When P91.32=1, if the bus voltage is less than
the starting frequency
voltage*P91.33), output
decrease, the regulated target frequency is
(Rated frequency*Present
voltage/Standard bus voltage); if the bus
voltage increases but it does not reach the
restoration voltage
voltage*(P91.33+5%), the output frequency
remains unchanged;
continuously decreases, the output frequency
continuously decreases; if the bus voltage rises
and becomes greater than the restoration
voltage, the output frequency increases to the
rated frequency.
