6.33.8 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. When
tripping is selected, enter the detection time to tripping. 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.
Title Function Adjustment range Default setting
H Low current detection hysteresis width ~%
H Low current trip selection
: No trip
:Trip
H Low current detection current ~%
H Low current detection time ~ sec.
<Example of operation>
Output terminal function: 26 (UC) Low current detection
H= (No trip)
Ex.) When outputting low current detection signals through output terminal OUT1
Title Function Adjustment range Example of setting
H Output terminal function selection 1(OUT1) ~
Note:To put out signals to the terminal OUT2, select the parameter H.

+When H= (tripping), the inverter will trip if low current lasts for the period of time set with H.
After tripping, the low current signal remains ON.
6.33.9 Detection of output short circuit
H : Selection of short circuit detection at starting
• Function
Detects a short-circuit on the output side of the inverter.
Title Function Adjustment range Default setting
H
Selection of short circuit
detection at starting
:Each time (standard pulse)
:Only one time after power is turned on
:Each time (short pulse)
:Only one time after power is turn on (short pulse)
H ･････････ , : Standard —— detecting at starting
, : A check is made once at the first start of operation after the power is turned on or the
inverter is reset.
Note: When operating a high-speed motor, set H to . Any other setting may cause the motor to malfunction,
because a high-speed motor has a very low impedance.
