PID Automatic selection range upper limit
( : 1 to 8)
When using automatic selection of PID sets, use this setting to set an upper limit for each PID set.

• MV lower limit
The setting range differs for standard control and heating/cooling
control.
The cooling MV of heating/cooling control is expressed as a
negative value.
• The MV limit function does not operate on a position proportional
type during floating control, and thus the setting is not effective in
this case.
Setting data
Standard control:
MV lower limit + 0.1 to 105.0
MV upper limit
Heating/cooling control:
0.0 to 105.0
Standard control:
-5.0 to MV upper limit - 0.1
MV lower limit
Heating/cooling control:
-105.0 to 0.0
The following MVs take precedence over the MV limits:
• Manual MV
• Manipulated variable at stop
• MV at PV error

• Set the automatic selection range upper limit for PID Set Nos. 1 to 8.
• Note that the limit for PID Set 8 is fixed at 110% of the sensor setting
range, and thus does not need to be set.
• This value is applied to the PV (present value) or DV (deviation) set
in "PID set automatic selection data". The initial setting is "PV".
