Description
Sets the upper limit value of integral
control output.
Sets the parameter as a percentage
based on the maximum frequency as
100%.
Set this parameter to the primary
delay time constant for the frequency
reference after PID control.
* Normally, the default setting does
not need to be changed.
Sets the detection method of feed-
back loss in PID control.
0: Feedback loss detection disabled.
1: Feedback loss detection enabled
(Nonfatal error: FbL warning)
2: Feedback loss detection enabled
(Fatal error: FbL fault)
Sets the detection level of feedback
loss.
Sets the parameter as a percentage
based on the feedback value equiva-
lent to the maximum frequency as
100%.
Sets the detection time of feedback
loss.
* If the detection level set in n137 or
lower is detected for the set time in
n138, the result will be determined
as feedback loss.
Select the energy-saving control func-
tion.
0: Disabled
1: Enabled
* This parameter is enabled in V/f
control mode only.
Sets the coefficient for the primary
level of energy-saving control.
* The constant automatically chan-
ges according to the motor code in
n158. Make fine adjustments of the
contact if necessary after setting
the motor code in n158.
These parameters prevent the output
voltage of the Inverter from dropping
excessively so that the motor will not
stall or come to a stop at the primary
level of energy-saving control.
Sets the lower limit of output voltage Sets the lower limit of output voltage
as a percentage at each frequency
based on the rated motor voltage as
100%.
* Normally, the default settings do
not need to be changed.
