6.33.7 Input phase failure detections
: Input phase failure detection mode selection
• Function
This parameter detects inverter input phase failure. At the occurrence of a phase failure, the
protection message is displayed.
=
: No tripping (Failure signal FL deactivated).
=
: This parameter detects inverter input phase failure. If the inverter detects an open phase failure, it
trips.

Note 1: Setting
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 (

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