st-b
ST Stable Range
Temperature input, standard control, 2-PID control
must be set.
The ST parameter must be set to ON.
• The setting of this parameter determines when ST operates.
This parameter cannot be used when ST is set to OFF.

tidu
Integral/Derivative Time Unit Control must be set to 2-PID control.
This parameter sets the time unit for the Integral Time, Integral Time (Cooling), Derivative
Time, and Derivative Time (Cooling) parameters.
Note: The Integral/Derivative Time Unit parameter changes to 0.1 when the RT (robust tuning)
parameter is changed from OFF to ON.
