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

• These settings are normally used at the default values.
• "AT calculated gain" specifies the gain used when PID values are
calculated during AT. A smaller gain provides greater adaptability,
while a larger gain provides greater stability.
• "AT hysteresis" is used to set the value of hysteresis for ON/OFF
switching during the limit cycle while AT is being run.
• "Limit cycle MV amplitude" is used to set the MV amplitude during
the limit cycle while AT is being run.
• This is effective when P
selected in proportional control.
• "Temporary AT execution judgement deviation" is used to judge if
temporary AT is excute or not for running temporary AT. When AT is
excuted while, the deviation is greater than the set value, temporary
AT runs.
