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.
Set output phase loss detection time in 1-s
units.
Inverter will detect output phase loss if
current as large as or less than value set
with n082 flows continuously for period exceeding
set time.
