Name
Output open-
Set output phase loss detection time in 1-s
phase detec-
units.
tion time
Inverter will detect output phase loss if cur-
rent as large as or less than value set with
n082 flows continuously for period exceed-
ing set time.
PID control
0: No PID control.
function selec-

control.
2: PID control with feedback derivative
control.
3: PID control with negative feedback
characteristic control.
Feedback ad-
Fine tuning gain for PID feedback value.
justment gain
Proportional
Set proportional gain for proportional con-
gain (P)
trol.
Proportional control will be invalid if value
set to 0.0.
Integral time (I)
Set integral time with 1 s units for integral
control.
Integral control will be invalid if value is set
to 0.0.
Derivative time
Set derivative time with 1 s units for deriv-
(D)
ative control.
Derivative control will be invalid if value is
set to 0.0.
PID offset ad-
Set PID offset with 1% units based on
justment
max. frequency set with n012 as 100%.
Integral (I) up-
Set upper limit of output with 1% units after
per limit
integral control is performed based on
max. frequency set with n012 as 100%.
PID primary
Set PID primary-delay time constant with
delay constant
1 s units for frequency reference after PID
control is performed.
Feedback loss
0: Feedback loss is detected.
detection selec-
1: Feedback loss is not detected.
tion
Feedback loss
Set feedback loss detection level with 1%
detection level
units.
Feedback loss
Set feedback loss detection time with 1 s
detection time
units.
