PID Setting Level Section 5-6
• MV Upper Limit
The setting range depends on whether standard, position-proportional
(closed) control, or heating/cooling control is used. In addition, the cooling
MV during heating/cooling control is expressed as a negative value.
• MV Lower Limit
The setting range depends on whether standard, position-proportional
(closed) control, or heating/cooling control is used. In addition, the cooling
MV during heating/cooling control is expressed as a negative value.

These parameters set the upper limit for each PID set when PID sets are
selected automatically.
• These parameters are used to set the automatic selection range upper
limits for PID sets 1 to 8.
• The sensor setting range for PID set 8 is 32,400 EU for temperature
inputs and 105.0% for analog inputs. This parameter does not need to be
set.
• These values apply to the PV (process value), DV (deviation), or SP (set
point) set in the PID Set Automatic Selection Data parameter. The default
setting is PV.
