H : Input phase failure detection mode selection
•
Function
This parameter detects inverter input phase failure. At the occurrence of a phase failure, the
GRJK
protection message is displayed.
H=: No tripping (Failure signal FL deactivated).
H=: This parameter detects inverter input phase failure. If the inverter detects an open phase failure, it
trips.
[Parameter setting]
Title Function Adjustment range Default setting
H Input phase failure detection mode selection :Disabled,:Enabled
Note 1: Setting H to (input phase failure detection: disabled) may result in a breakage of the capacitor in the
inverter main circuit if operation is continued under a heavy load in spite of the occurrence of an input phase
failure.
Note 2: When using a single-phase direct current to operate the inverter, disable this function (H=)

H : Low current detection time
• Function
If the current is lower than
H
level and passes for a time longer than
H
, the inverter trips.
Trip information is displayed as “
WE
.”
H=: No tripping (Failure signal FL deactivated).
A low current alarm can be put out by setting the output terminal function selection parameter.
H=: The inverter will trip (the failure signal FL will be activated) if a current below the current set with
H flows for the period of time specified with H.
