• The MV Upper Limit and MV Lower Limit parameters set the upper and lower limits of the
manipulated variable. When the calculated manipulated variable exceeds the upper or
lower limit value, the upper or lower limit value will be the output level.
Function
• The set value is saved in the MV Upper Limit and MV Lower Limit parameters for the
current PID set.
• MV Upper Limit
Setting
Standard control
Close position-proportional control
Heating/cooling control
• MV Lower Limit
The MV for the cooling control output during heating/cooling control is expressed as a
negative value.
