7.2.3 PID Group
PID parameters can be set in this group.
PID group is common to Fixed value control and program control.
To enter the PID group, follow the procedure below.
(1)
Press the
key twice in PV/SV Display Mode.
The unit proceeds to the PID group.
(2)
Press the
key.
If PID zone function “Not used” is selected in [PID zone function],
the unit will proceed to ‘OUT1 proportional band 1’.
If PID zone function “Used” is selected in [PID zone function],
the unit will proceed to ‘PID zone value 1’.

Factory Default
PID zone value 1
0
• Sets Reference value 1 to switch PID zone parameters of the PID
zone function.
(PID zone parameters: OUT1 proportional band 1 to OUT1 rate-of-
change 1)
Not available if PID zone function “Not used” is selected in [PID zone
function].
One zone contains from “PID zone value 1” to “OUT1 rate-of- change
1”.
When SV is lower than Reference value 1 (PID zone value 1), control
is performed with these PID zone parameters.
• Setting range: Scaling low limit value to Scaling high limit value
OUT1 proportional band 1
10
• Sets proportional band 1 for OUT1.
OUT1 becomes ON/OFF control when set to 0 or 0.0.
• Setting range: 0 to Input span ( )
DC voltage, current inputs: 0.0 to 1000.0%
OUT2 proportional band 1
1.0 times
• Sets proportional band 1 for OUT2.
OUT2 becomes ON/OFF control when set to 0.0.
Available only when D option is ordered.
• Setting range: 0.0 to 10.0 times (Multiplied value of OUT1
proportional band)
Integral time 1
200 seconds
• Sets integral time 1 for OUT1.
Setting the value to 0 disables this function.
Auto-reset can be performed when PD is control action (I=0).
• Setting range: 0 to 3600 seconds
