<Example of operation>
Output terminal function: 26 (UC) Low current detection
= (No trip)
Ex.) When outputting low current detection signals through output terminal OUT1
Note: To put out signals to the terminal OUT2, select the parameter .
Output current [%]
When = (tripping), the inverter will trip if low current lasts for the period of time set with .
After tripping, the low current signal remains ON.
6.33.9 Detection of output short circuit
: Selection of short circuit detection at starting
Detects a short-circuit on the output side of the inverter.
················· , , : Standard —— detecting at starting
Note: If the input voltage is rather high (480V as a guide) or the inverter is used to operate a high-speed motor, set
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 is set to or
, then set to or .
6.33.10 Overtorque trip
: Overtorque trip selection
: Overtorque detection level during power running
: Overtorque detection level during regenerative braking
: Overtorque detection time
: Overtorque detection hysteresis
Output terminal function selection 1(OUT1)
:Each time (standard pulse)
:Only one time after power is turned on
:Each time (short pulse)
Selection of short circuit
:Only one time after power is turn on (short pulse)
detection at starting
:Each time (Extremely shot-time pulse)
:Only one time after power is turn on (Extremely
, , : A check is made once at the first start of operation after the power is turned on or the
inverter is reset.
