D5012 ZON Zone PID selection
UT35A/UT32A
If set to “SP group number selection,” allows PID
constants to be selected for each SP group.
If set to “Zone PID selection,” automatically selects
PID constants according to the range set in the
Reference point.
0: SP group number selection 1
1: Zone PID selection (selection by PV)
2: Zone PID selection (selection by target SP)
3: SP group number selection 2
4: Zone PID selection (selection by SP)
UP35A
0: Segment PID selection
1: Zone PID selection (selection by PV)
2: Zone PID selection (selection by target SP)
4: Zone PID selection (selection by SP)
5: Local PID selection
* If set to “Segment PID selection,” allows PID
constants to be selected for each segments.
* If set to “Zone PID selection,” automatically
selects PID constants according to the range set
in the Reference point.
* If set to “Local PID selection,” local PID is selected
irrespective of the operation modes.
