Normally use the default values for these parameters.
The AT Calculated Gain parameter sets the gain for when PID values are
calculated using AT. When emphasizing response, decrease the set
value. When emphasizing stability, increase the set value.
The AT Hysteresis parameter sets the hysteresis for limit cycle operation
during autotuning when switching ON and OFF.
The Limit Cycle MV Amplitude parameter sets the MV amplitude for limit
cycle operation during autotuning.
Parameter name Setting range Unit Default
AT Calculated Gain 0.1 to 10.0 --- 1.0
AT Hysteresis Temperature
input: 0.1 to
3,240.0
°C or °F 0.8 (See note 1.)
Analog input:
0.01 to 9.99
%FS 0.20
Limit Cycle MV
Amplitude (See note
2.)
5.0 to 50.0 % 20.0
Note (1) When the temperature unit is °F, the default is 1.4.
(2) With standard models, this is displayed during standard control. With position-proportional
models, this is displayed during close control (when
there is a potentiometer input).
