ADJUSTMENT
130
PID integral time
0.1s 1s
0.1 to 3600s
When deviation step is input, time (Ti) is the time
required for integral (I) action to provide the same
manipulated variable as the proportional (P) action.
As the integral time decreases, the set point is
reached earlier but hunting occurs more easily.
9999 No integral control.
131
PID upper limit
0.1% 9999
0 to 100%
Set the upper limit value.
If the feedback value exceeds the setting, the FUP
signal is output. The maximum input (20mA/5V/
10V) of the measured value (terminal 4) is
equivalent to 100%.
9999 No function
132
PID lower limit
0.1% 9999
0 to 100%
Set the lower limit value.
If the measured value falls below the setting range,
the FDN signal is output.
The maximum input (20mA/5V/10V) of the
measured value (terminal 4) is equivalent to 100%.
9999 No function
133
PID action set point
0.01% 9999
0 to 100% Used to set the set point for PID control.
9999 Terminal 2 input voltage is the set point.
134
PID differential time
0.01s 9999
0.01 to
10.00s
For deviation lamp input, time (Td) required for
providing only the manipulated variable for the
proportional (P) action. As the differential time
increases, greater response is made to a deviation
change.
9999 No differential control.
553
PID deviation limit
0.1% 9999
0 to 100.0%
Y48 signal is output when the absolute value of
deviation amount exceeds the deviation limit value.
9999 No function
554
PID signal operation
selection
10
0 to 3,
10 to 13
Select the operation to be performed at the
detection of upper, lower, and deviation limit for
the measured value input. The operation for PID
output suspension function can be selected.
575
Output interruption
detection time
0.1s 1s
0 to 3600s
If the output frequency after PID operation remains
lower than the Pr. 576 setting for longer than the time
set in Pr. 575, the inverter stops operation.
9999 Without output interruption function
576
Output interruption
detection level
0.01Hz 0Hz 0 to 400Hz
Set the frequency at which the output interruption
processing is performed.
577
Output interruption
cancel level
0.1% 1000%
900 to 1100%
Set the level (Pr.577 - 1000%) to release the PID
output interruption function.
C42

PID display bias
coefficient
0.01 9999
0 to 500.00
Set the coefficient on bias side (minimum) of
terminal 4 input.
×
9999 Displayed in %.
C43
(934)
PID display bias
analog value
0.1% 20%
0 to 300.0%
Set the converted % on bias side (minimum)
current /voltage of terminal 4 input.
×
C44
(935)
PID display gain
coefficient
0.01 9999
0 to 500.00
Set the coefficient on gain side (maximum) of the
terminal 4 input.
×
9999 Displayed in %.
C45
(935)
PID display gain
analog value
0.1% 100%
0 to 300.0%
Set the converted % on gain side (maximum) of
current/voltage of terminal 4 input.
