mani
This parameter sets the initial value of the manual MV to use after control moves from Auto-
matic Mode to Manual Mode.
Function
Standard control and position-proportional control: −5.0 to 105.0
Setting
Heating/cooling control: −105.0 to 105.0
If the Manual MV Limit Enable parameter is set to ON, the setting range will be the MV lower
limit to the MV upper limit.

rt
This parameter executes robust tuning (RT).
• When autotuning is executed with RT selected, PID constants are automatically set that
make it hard for control performance to degenerate even when control object's
characteristics change.
Function
• Even when hunting occurs for PID constants when auto-tuning is executed in normal
mode, it is less likely to occur when auto-tuning is executed in RT Mode.
Setting
Note: The Integral/Derivative Time Unit parameter changes to 0.1 when the RT (Robust Tuning)
parameter is changed from OFF to ON.

Control must be set to 2-PID control.
A Position-proportional Model set to Close Control
with the Direct Setting of Position-proportional MV
parameter set to ON must be used.
Control must be set to 2-PID control. If the input
type is set for a temperature input, either the
Standard or Heating/Cooling parameter must be set
to standard control or, if the Standard or
Heating/Cooling parameter is set to
heating/cooling control, the Heating/Cooling
Tuning Method parameter must not be set to air or
water cooling.
Or, a Position-proportional Model must be used.
