• Use the MV Upper Limit and MV Lower Limit parameters to set
upper and lower limits for the MV. When the Controller calculates an
MV that is outside of the upper and lower limits, the upper or lower-
limit is output.
• MV Upper 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.
• 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
Control Model during floating control, and thus the setting is not
effective.
Parameter
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
MV Lower Limit
Heating/cooling control:

The following MVs take priority over the MV limits:
• Manual MV
• MV at Reset
• MV at PV error
