• The disturbance overshoot adjustment function adjusts the control
waveform when disturbance occurs.
• To use this function, set the Disturbance Overshoot Adjustment
Function parameter to "ON" (the default setting is "OFF").
• The disturbance response waveform can be adjusted using the
Disturbance Gain and Disturbance Time Constant parameters.
• The Disturbance Gain parameter can be increased to reduce
overshooting when disturbance occurs.
• The Disturbance Gain parameter can be decreased to increase
overshooting when disturbance occurs.
• When the Disturbance Gain parameter is set to 0, the disturbance
overshoot adjustment function does not operate.

• The reset time after disturbance can be lengthened by increasing
the disturbance time constant. (The default value of 1 is normally
used for the disturbance time constant. If adjustment of the distur-
bance gain alone is not sufficient, this value can be adjusted for fine-
tuning.)

• The waveform may vary from that in the diagram depending on
differences in the object of control and differences in PID constants.
