3.5.14 Group 3.12: PID-controller 1
3.5.14.1 Basic settings
Table 39.
Code Parameter Min Max Unit Default ID Description
M3.12.1.1 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%.
M3.12.1.2 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.
M3.12.1.3 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%.
M3.12.1.4 Process unit selection 1 40 1 1036 Select unit for actual value.
M3.12.1.5 Process unit min Varies Varies Varies 0 1033
M3.12.1.6 Process unit max Varies Varies Varies 100 1034
M3.12.1.7 Process unit decimals 0 4 2 1035
Number of decimals for pro-
cess unit value
M3.12.1.8 Error inversion 0 1 0 340
0 = Normal (Feedback < Set-
point -> Increase PID output)
1 = Inverted (Feedback <
Setpoint ->
Decrease PID out-
put
)
M3.12.1.9 Dead band hysteresis Varies Varies Varies 0 1056
Dead band area around the
setpoint in process units.The
PID output is locked if the
feedback stays within the
deadband area for a pre-
defined time.
M3.12.1.10 Dead band delay 0.00 320.00 s 0.00 1057
If the feedback stays within
the dead band area for a pre-
defined time, the output is
locked.
