Suppressing Function
Select [OFF] or [Overshoot].
Ramp-rate Time Unit
Set the ramp-rate time units.
SP Ramp-down-rate
Set between 1 digit and EUS (100%) of the measurement span.
SP Ramp-up-rate

Tag
Specify a tag.
Use a maximum of 8 characters.
Tag Comment

Use a maximum of 8 characters.
• Zone PID
Specify the internal loop control zone PID.
The zone PID setting appears when [Zone PID] is [ON] in [Setup] - [Control Action].
Reference Point (displayed when the PID number is 3 or higher)
Specify the reference point with the measurement input span EU (0.0 to 100.0%).
The number of points depends on the number of PID. ([PID Number]-2.) Therefore, it
is not displayed when the PID number is 2 or less.
The value of each point is such that 1≤2≤...≤6 is set.
Switching Hysteresis
Specify the switching hysteresis value with the measurement input span EU (0.0 to
10.0%). It is not displayed when the PID number is 1 or less (or 2 or less with style
number S1).
