6.17.5 Output phase failure detection
H : Output phase failure detection mode selection
•Function
This parameter detects inverter output Phase failure. If the Phase failure status persists for one second or more, the tripping function and the FL relay will be activated. At the same time, a trip information GRJQ will also be displayed.
Set H to to open the
Detection errors may occur for special motors such as
H=: No tripping (FL relay deactivated).
H=: With the power on, the phase failure detection is enabled only at the start of the first operation. The inverter will trip if the Phase failure status persists for one second or more.
H=: The inverter checks for output phase failures each time it starts operation. The inverter will trip if the Phase failure status persists for one second or more.
H=: The inverter checks for output phase failures during operation. The inverter will trip if the Phase
6failure status persists for one second or more.
H=: The inverter checks for output phase failures at the start of and during operation. The inverter will trip if the Phase failure status persists for one second or more.
H=: If it detects an
The inverter does not check for output phase failures when restarting after a momentary power failure.
Note: A check for output phase failures is made during
