P9-62
Instantaneous power-off action
judgment voltage
Factory default
80.0%
Setting range
60.0% ~ 100.0% (standard bus voltage)
The function is that, when instantaneous power off or voltage drops suddenly, the inverter will reduce
output speed to
decrease compensation voltage for DC bus which is generated by the load feedback
energy, so that keep the inverter running.
P9-59=1: When instantaneous power off or voltage drops suddenly, the inverter decelerates, when bus
voltage returns to normal, the inverter accelerates to the setting frequency and runs. Normal bus voltage
lasts for longer than the time set by P9-61 means that bus voltage returns to normal.
P9-59=2: When instantaneous power off or voltage drops suddenly, the inverter decelerates to stop.
