Note The waveform shown in the diagram above will vary depending on the control
object's characteristics and the PID constant settings.
Starting Conditions
for the Disturbance
Overshoot
Adjustment Function
The Disturbance Overshoot Adjustment Function will operate after the pro-
cess value (PV) has stabilized in the Disturbance Rectification Band and the
deviation is larger than the Disturbance Judgment Width.
• When the Disturbance Judgment Width is positive, the Disturbance Over-
shoot Adjustment Function will operate if a disturbance causes the pro-
cess value (PV) to fall. When the Disturbance Judgement Width is
negative, the Disturbance Overshoot Adjustment Function will operate if a
disturbance causes the process value (PV) to rise.
• The Disturbance Overshoot Adjustment Function will not operate in the
following situations:
• When the Disturbance Rectification Band or Disturbance Judgment
Width parameter is 0
• When the set point is changed (when the set point change width ex-
ceeds the Disturbance Rectification Band)
• During autotuning
5-3-8 Operation during Errors
This parameter can be used to select the operation when an error occurred.
Note This parameter can be set only when operation is stopped.
When this parameter has been changed, the new setting becomes effective
the next time a software reset is performed for the Unit or the next time power
is turned ON.
