Overtorque
detection
n074 Overtorque
detection func-
tion selection
0: Inhibits Inverter from detecting overtor-
que.
1: Inverter will detect overtorque only dur-
ing speed agreement and continue run-
ning with warning after detection.
2: Running Inverter will detect overtorque
and continue running with warning after
detection.
3: Inverter will detect overtorque only dur-
ing speed agreement and turn OFF
output for safety when overtorque is
detected.
4: Running Inverter will always detect
overtorque and turn OFF output for
safety when overtorque is detected.

n075 Overtorque
detection level
Set overtorque detection current in 1%
units based on rated output current of In-
verter as 100%.

n076 Overtorque
detection time
Set overtorque detection time in 1-s units.
Overtorque will be detected if current larg-
er than value set with n075 flows for the
set time or more.

Timer function
n077 Timer function
ON delay time
Set time lag between moment timer func-
tion input turns ON and moment timer
function output turns ON.
Valid if multi-function input and multi-func-
tion contact output are set to timer func-
tion.

n078 Timer function
OFF delay time
Set time lag between the moment the tim-
er function input turns OFF and the
moment the timer function output turns
OFF.
Valid if multi-function input and multi-func-
tion contact output are set to timer func-
tion.

I/O phase loss
detection
n080 Input open-
phase detec-
tion level
Set input phase loss detection level to per-
centage of main circuit DC voltage.
200-V class: 200 VDC as 100%
400-V class: 800 VDC as 100%

n081 Input open-
phase detec-
tion time
Set input phase loss detection time.
Detection time = 1.28 x n n081
Inverter will detect input phase loss if volt-
age as large as or larger than value set
with n080 is imposed continuously for peri-
od exceeding set time.

n082 Output open-
phase detec-
tion level
Set output phase loss detection level in
1% units based on rated output current of
Inverter as 100%.
Output phase loss detection will be invalid
if value is set to 0.
