·
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.
P417
Allowable time of power off Default value 5.0
Range
0-10.0
unit
0.1
P417 sets allowable time of power failure, if time of power failure
exceeds set value, power failure restart is invalid.
P418
Flank restart current limiting level Default value 150
Range
0-200
Unit
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.
