3) RAMP FUNCTION
It is a rate of set value to arrive to set value
according to setting temperature and time.
ex) Present temp 20℃, set value 100℃, 2 0 per min.
1) Initial uprising set value(up,rt) : 100℃
2) Unit time : Minute min)

4) ZOOM FUNCTION
When you choose Zoom function ON in Group control,
you can see a temperature with zooming as soon as you
select ON. The tenperature will be in center of paper.
ex) Scale : 0.0 ~ 100.0
Zoom ON : ZOOM IN 》PV. 25.5℃ at the center

b) LOW PV TYPE AUTO-TUNING
The Auto tuning function automatically measures,
computes and sets the optimum Proportional band(P),
Integral time(I), and Deri-vative time(D). When Auto-tuning,
the controller performs ON/OFF
control and determine proper P.I and D. (Limit cycle type)
RT9-1 series controller have two types of Auto-tuning as
b e l o w .
󱃦 Standard type auto-tuning :
This type is based on set point value (SV)
󱃧 Low PV type auto-tuning :
This type is based on the value 10% lower than
the set point value (SV)
2) Auto-tuning in Zone PID
Zone PID automatically sets PID group in accordance
with a measured value. In Zone PID, auto-tuning sets
the proper PID value by recognizing a mid-value of
reference point as set point value.

Fuzzy control eliminates overshoot using Fuzzy Logic.
Employing Fuzzy control and Auto-tuning, the
controller effectively control as below.
󱃦 When the controller starts control at the position
which has a big gap between SV and PV.

Control output is set in high and low limit as operating range.
Output limit is -5~105% of output.

When A/D error or input disconnection occur in auto
mode, PID output is cut and than Pre-set output is
operated. (PO Output)
