AT Calculated Gain
Control must be set to 2-PID control.
at-h
AT Hysteresis
lcma
Limit Cycle MV Amplitude
Control must be set to 2-PID control or close
position-proportional control.
• 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.
