6.26.8 Control mode for low current
H
: Low current detection hysteresis width
H
: Low current trip selection
H
: Low current detection current
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
.
