LBA detection time
Conditions of Use
The LBA (Loop Break Alarm) function
must be assigned as an output.
• This parameter is automatically set b y AT execution (excluding AT execution in a
ON/OFF control).
• The LBA is output if the change width of the process value falls below 0.2 %full-
scale of the time preset to this parameter when the manipulated variable is set in
the “MV upper limit” or “MV lower limit” parameters.
• The LBA function is disabled when this parameter is set to “0”.

MV at stop
MV at PV error
Conditions of Use
Advanced PID control
• The “MV at stop” parameter sets the manipulated variable when operation stops
on a standard type controller. On a position-proportional type controller, this
parameter sets the action (close/hold/open) when operation stops.
• The “MV at PV error” parameter sets the manipulated variable when an input
error occurs. On a position-proportional type controller, this parameter sets the
action (close/hold/open) when an input error occurs.
• Standard type
Control Method Setting Range
Unit Default
Standard -5.0 to 105.0 % 0
Heating and cooling -105.0 to 105.0 % 0
The manipulated variable at the cooling side during heating and cooling control is
expressed as a negative value.
• Position-proportional type
Setting Range
Unit Default
[ ]: Hold/[ ]: Open/[ ]: Close None
