At Execute/Cancel; Set Point 0; Set Point 1; Set Point 2 - Omron E5AK User Manual

AT Execute/Cancel

• Selects the limit cycle of MV change width (40% or 100%) for execution. After AT
execution, the "PID" and the "LBA detection time" (LBA: Loop Break Alarm)
parameters are set automatically.
Function
• During heating and cooling control or position-proportional control, only 100%AT
can be executed.
• When this parameter is selected, the setting becomes [

Set point 0

Set point 1

• Switches set points 0 to 3 by event input for use as the set point (local SP).
• Of set points 0 to 3, the number of valid set points is designated by the "multi-SP
function" parameter.
Function
• The following table shows the relationship between event input and the selected
parameter.

• When the set point has been changed, the setting of whichever is selected in event
input, "set point 0" to "set point 3", is linked and changed.
• The decimal point position is dependent on the selected sensor during tempera-
ture input and on the results of scaling during analog input.
