Startup conditions
The overshoot suppression function is started when the deviation (E) becomes larger than 0.2% of the input span by
performing any of the following operations:
• Changing the set value (SV)
• Changing the state of the module from control stop to control start
• Powering on the module
Completion conditions
When either of the following conditions is satisfied, the overshoot suppression function is completed and the control shifts to
the PID control.
• The deviation (E) becomes equal to or smaller than 1% of the deviation (E) at the startup of the overshoot suppression
function.
• The process value (PV) reaches the set value (SV).
Stop conditions
When any of the following conditions is satisfied, the overshoot suppression function is stopped and the control shifts to the
PID control.
• An operating condition becomes unsatisfied.
• Temperature measurement lasts for 7200 seconds.
• The sensor correction value and the primary delay digital filter setting are changed.
• The overlap/dead band setting is changed.
