6 Parameters
rt
This parameter executes robust tuning (RT).
• When AT or ST is executed with RT selected, PID constants are automatically set which
make it hard for control performance to degenerate even when control object
characteristics are changed.
Function
• Even when hunting occurs for PID constants when AT or ST is executed in normal mode,
it is less likely to occur when AT or ST 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.

Setting range
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.
Default
off
HB and HS alarms must be supported.
