6.29.5 Output phase failure detection

f605 : Output phase failure detection selection
 Function
f605=0: No tripping. (Failure signal FL not activated)
f605=1: With the power on, the output phase failure will be detected when the first operation starts.
f605=2: The inverter checks for output phase failures every time the operation starts. The inverter will trip
6
f605=3: The inverter checks for output phase failures during operation. The inverter will trip if the phase
f605=4: The inverter checks for output phase failures at the start and during operation. The inverter will
f605=5: If the inverter detects an all-phase failure, it will restart on completion of reconnection. The
[Parameter setting]
f605
Note1) A check for output phase failures is made during auto-tuning, regardless of the setting of this parameter.
Note2) When parameter pt=5 or 6 is selected, f605=3 to 5 do not work.

This parameter detects inverter output phase failure. If the phase failure status persists for one
second or more, trip occurs and the failure signal FL will be activated. Trip information epho will be
displayed.
Set f605 to 5 to open the motor-inverter connection by switching commercial power operation to
inverter operation.
Detection errors may occur for special motors such as high-speed motors.
The inverter will trip if the phase failure status persists for one second or more. (Failure signal FL
activated)
if the phase failure status persists for one second or more. (Failure signal FL activated)
failure status persists for one second or more. (Failure signal FL activated)
trip if the phase failure status persists for one second or more. (Failure signal FL activated)
inverter does not check for output phase failures when restarting after a momentary power failure.
