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.

• Function
Detects a short-circuit on the output side of the inverter.
Title Function Adjustment range Default setting

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)
:Each time (Extremely shot-time pulse)
:Only one time after power is turn on (Extremely
shot-time 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: If the input voltage is rather high (480V as a guide) or the inverter is used to operate a high-speed motor, set
H to or . Any other setting may cause the motor to malfunction, because a high-speed motor has a
very low impedance. If the inverter malfunctions for reasons of impedance even though H is set to or
, then set H to or .
