select "

" again.
The parameter information also changes automatically
depending on the ramp/soak state.
• “
GS
” (during guaranty soak): PV exceeds the range for
guaranty soak when guaranty soak is on.
• “
End
” (end) : Ramp/soak ends.

Auto-tuning
Running auto-tuning automatically sets the optimal PID.
• Range oFF : Stop/Finish
on : Auto-tuning (normal type) starts
Lo : Auto-tuning (low PV type) starts
There are two types of auto-tuning.
Running Auto-tuning
Normal type Requests PID and starts ON/OFF
operation with SV as the baseline.
Low PV type Requests PID and ON/OFF operation at
a baseline of SV-10%. Use this setting if
you are trying to prevent overshoot.
Caution
ON/OFF control is performed during auto-tuning, so SV may
be overshot. If you are trying to minimize overshooting, use
low PV auto-tuning.
Refer to
See "Control Methods" (p. 101) for more about auto-tuning.
