Code Parameter Min Max Unit Default ID Description
P3.12.1.1 PID gain 0.00 1000.00 % 100.00 118
If the value of the parameter
is set to 100% a change of
10% in the error value
causes the controller output
to change by 10%.
P3.12.1.2 PID integration time 0.00 600.00 s 1.00 119
If this parameter is set to
1,00 second a change of
10% in the error value
causes the controller output
to change by 10.00%/s.
P3.12.1.3 PID derivation time 0.00 100.00 s 0.00 132
If this parameter is set to
1,00 second a change of
10% in the error value during
1.00 s causes the controller
output to change by 10.00%.
P3.12.1.4 Process unit selection 1 38 1 1036 Select unit for actual value.
P3.12.1.5 Process unit min Varies Varies Varies 0 1033
The setpoint and feedback
values are internally han-
dled as percent, but can be
scaled to process units on
the panel.
Process Unit selection
selects unit. Process Unit
Min and Max are the process
values corresponding to 0%
and 100% respectively
(scaled linearly in between).
Process Unit Decimals is for
choosing how many deci-
mals to show.
P3.12.1.6 Process unit max Varies Varies Varies 100 1034
The setpoint and feedback
values are internally han-
dled as percent, but can be
scaled to process units on
the panel.
Process Unit selection
selects unit. Process Unit
Min and Max are the process
values corresponding to 0%
and 100% respectively
(scaled linearly in between).
Process Unit Decimals is for
choosing how many deci-
mals to show.
P3.12.1.7 Process unit decimals 0 4 2 1035
Number of decimals for pro-
cess unit value
P3.12.1.8 Error inversion 0 1 0 340
0 = Normal (Feedback < Set-
point -> Increase PID output)
1 = Inverted (Feedback <
Setpoint ->
Decrease PID out-
put
)
