Code Parameter Min Max Unit Default ID Description
P3.13.1.1 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%.
P3.13.1.2 Integration Time 0.00 600.00 s 1.00 119
If this parameter is set to
1,00s a change of 10% in the
error value causes the con-
troller output to change by
10.00%/s.
P3.13.1.3 Derivation Time 0.00 100.00 s 0.00 132
If this parameter is set to
1,00s a change of 10% in the
error value during 1.00 s
causes the controller output
to change by 10.00%.
P3.13.1.4 ProcessUnitSel. 1 38 1 1036 Select unit for actual value.
P3.13.1.5 ProcessUnitMin Varies Varies Varies 0 1033
Value in Process units at 0%
feedback or setpoint.
This scaling is done for moni-
toring purpose only. The PID
controller still uses the per-
centage internally for feed-
backs and setpoints.
P3.13.1.6 ProcessUnitMax Varies Varies Varies 100 1034 See above.
P3.13.1.7 ProcessUnitDeci 0 4 2 1035
Number of decimals for pro-
cess unit value
P3.13.1.8 Error inversion 0 1 0 340
0 = Normal (Feedback < Set-
point -> Increase PID output)
1 = Inverted (Feedback < Set-
point -> Decrease PID output)
P3.13.1.9 Dead Band 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.
P3.13.1.10 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.
