0: Inhibits Inverter from detecting overtorque.
1: Inverter will detect overtorque only during
speed agreement and continue running
with warning after detection.
2: Running Inverter will detect overtorque
and continue running with warning after
detection.
3: Inverter will detect overtorque only during
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.
Set overtorque detection current in 1%
units based on rated output current of Inverter
as 100%.
Set overtorque detection time in 1-s units.
Overtorque will be detected if current larger
than value set with n075 flows for the
set time or more.
Set time lag between moment timer function
input turns ON and moment timer
function output turns ON.
Valid if multi-function input and multi-function
contact output are set to timer function.
Set time lag between the moment the timer
function input turns OFF and the
moment the timer function output turns
OFF.
Valid if multi-function input and multi-function
contact output are set to timer function.
0: Inhibits overheating protection from
functioning.
1: Permits overheating protection to function.
Set input phase loss detection level to percentage
of main circuit DC voltage.
200-V class: 200 VDC as 100%
400-V class: 800 VDC as 100%
Set input phase loss detection time.
Detection time = 1.28 x n n081
Inverter will detect input phase loss if voltage
as large as or larger than value set
with n080 is imposed continuously for period
exceeding set time.
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.
