E5@C-T Digital Temperature Controllers User’s Manual (H185)
You can manually set individual PID constants in the Proportional Band, Integral Time, and Derivative
Time parameters in the PID Setting Level after you select the PID set number with the Display PID
Selection parameter.
If you change the setting of the Proportional Band, Integral Time, and Derivative Time parameters in the
Adjustment Level, the new settings are saved in the Proportional Band, Integral Time, and Derivative
Time parameters for the currently selected PID set.
For details on PID sets, refer to 5-13-1 PID Sets.
Additional Information
Proportional Action
When PID constants I (integral time) and D (derivative time) are set to 0, control is executed
according to proportional action. As the default, the center value of the proportional band
becomes the set point.
