Auto-tuning
1) Auto-tuning
This function is for automatic tuning of PID constants.
①”Auto-tuning” is in ModE.1.
②Press or to select ” ” , and then
press . “Auto-tuning” starts and the display becomes
its progressing screens (STEP 1 to 4).
③For cancellation of “Auto-tuning”, select END, and then
press .
Targeted value filter
1) Targeted value filter
This is a function suppressing overshoot. Control is executed
by computing an optimum SV.
2) ON/OFF of “Targeted value filter”
“Targeted value filter”is in “ModE.1”, and ON (enable) or OFF
(disable) is selectable . Press by selecting “ ” to
enable this function.
PID control
1) P (Proportional) action
①This is a basic action of PID control. It affects
responsiveness and stability. The proportional action only
results in offset.
②By setting the proportion band wider, the control stability
becomes better due to smaller amplitude of cycling and
longer cycle time, but the responsiveness becomes worse.
2) I (Integral) action
①This action can eliminate offset resulted from the
proportional action, but the stability becomes worse
because phase delays.
②By setting the integral time shorter (stronger integral action),
the responsiveness becomes better but overshoot
becomes larger.
3) D (Derivative) action
①This action compensates the delay of phase due to dead
time or delay factor. However, because the gain increases
in high frequency area, its strength has a limit.
②By setting the derivative time longer, the response to large
deviation becomes faster and the cycle is shortened.
However, for deviation with high frequency, the stability
becomes worse.
