b
PI process unit minimum
ID 1298
Minimum value:
-99999.99 varies
Maximum value:
PI Process Unit Max
Default value:
0.00 varies
Description:
Defines the minimum process unit value.
P7.1.5
b
PI process unit maximum
ID 1300
Minimum value:
PI Process Unit Min
Maximum value:
99999.99 varies
Default value:

P7.1.6
ab
PI error inversion
ID 1303
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Normal - if feedback is less than set-point, PI controller output increases.
1 = Inverted - if feedback is less than set-point, PI controller output decreases.
Description:
Defines the way the process value output reacts to the feedback signal.
P7.1.7
b
PI dead band
ID 1304
Minimum value:
-99999.99 varies
Maximum value:
99999.99 varies
Default value:
0 varies
Description:
PI dead band around setpoint in process units. This is the band where no actions occur to prevent oscillation or repeated activation/
deactivation of controller. The PI output is locked if the feedback stays within the dead band area.
