• Use this parameter to select Mode 0 or Mode 1 for the MV change
rate limit.
• When Mode 1 is selected, the MV change of rate limit functions only
with respect to increases in the MV.
Setting range
0: Mode 0
1: Mode 1

• These parameters are normally used at the default values.
• The AT Calculated Gain parameter specifies the gain used when
PID constants are calculated during AT. A smaller gain provides
greater adaptability, while a larger gain provides greater stability.
• The AT Hysteresis parameter is used to set the hysteresis when
switching ON/OFF during the limit cycle while AT is being executed.
• The Limit Cycle MV Amplitude parameter is used to set the MV
amplitude during the limit cycle while AT is being executed. This is
effective when P 0.00 in standard control, or when closed is
selected in proportional control.
• The Temporary AT Execution Judgement Deviation parameter is
used to determine whether temporary AT is executed when
executing AT. If AT is executed when the deviation is greater than the
set value, temporary AT is executed. This is effective when P
in standard control, or when closed is selected in proportional
control.
