Default value 5.0
Allowable time of power off
P417
Setting Range:0~10.00 Unit:0.1
P417 sets allowable time of power failure, if time of power failure exceeds set
value, power failure restart is invalid.
Example:
Use K1 (FWD), control running of inverter.
K1 closes, frequency conversion operates, when K1 is cut off, inverter stops.
When power is shut off and K1 remains closed, if power is on, inverter starts up
suddenly and it may be very dangerous. Please use other control methods, such
as three-wire system connection method.
Default value 150
Flank restart current limiting level
P418
Setting Range:0~200 Unit:0.1
When inverter implements flying restart, inverter tracing downwards from
setting frequency by highest speed, output current of inverter increases
relatively rapid and may exceeds protection unit setting by inverter, at this time,
inverter stops tracing, and output current of inverter falls back to common,
inverter continues tracing, setting value 100% of this parameter is rated current
of inverter, and protection unit when inverter searching may be set through
P418.
Default value 5
Flank restart time
P419
Setting Range:0~10 Unit:1
When inverter enabled the flying restart function, inverter tracing motor speed
downwards within the setting time. If it is not completed within setting time,
inverter protects.
In above example, when t value > P419 setting value, inverter protects
