Description
voltage*P91.33), output frequency starts
decrease, the regulated target frequency is
(Rated frequency*Present bus voltage/Standard
bus voltage); if the bus voltage increases but it
does not reach the restoration voltage (Standard
bus voltage*(P91.33+5%), the output frequency
remains unchanged; if the bus voltage
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.
P91.32 setting range:
0: Disable
1: Enable
P91.33 setting range: 70.0%–95.0% (Standard
bus voltage 537V)

Single direction limit: When the upward DEC
limit position is reached, the upward slow speed
area is entered, the VFD runs at
stops at sudden if the upward limit position is
reached; the upward speed is restricted, but the
downward speed is not restricted. Downward
