GAIN < 1.0
GAIN = 1.0
GAIN > 1.0
Description
Totally Response speed is faster, but Hunting occurs time by operating Differentiation &
Integration control which are stronger more than Auto-tuning P.I.D value.
Use Auto-tuning PID value as it stands.Totally Response speed is slower, but
Overshoot is decreased time by operating Differentiation & Integration control which are
smaller more than Auto-tuning PID value. It grows more stable situation.
⦁ Auto Tuning Gain(A/T Gain)
min value of
output range=-5 %
max range of
output range=105 %
The PID ZONE
/ buttons on the bottom in the left side of the PID setting screen [Fig. 102] is
the button for the automatic & the manual. For example, choosing
if you do auto-tuning of temp. at 80
℃, Temp. PID value is applied as the same with temp. in the zone 3,7,11 & zone 15. and if you do auto-tuning of
Humi. at 75%, Humi. P.I.D value is applied in the zone 11. In case of Manual mode, kindly refer to just SV in the
zone set according to the
.
When you check the value of P.I.D or input to collect directly, you can set P.I.D value of Moving Temp. & Humi.
in P.I.D setting screen [Fig. 103] by pushing Zone button wanted in the [Fig. 102]. However it is not possible to
set HYS(Hysteresis) setting screen cause it is not activated as a grey color. In order to set it, set [P] value as [0].
In this case, it’ s possible to set it because ON/OFF control is selected when set [P] value as [0].If you want to
use ON/OFF control only, set P.I.D zone number as [0]. It is possible to set each P.I.D zone’ s output range.
Please input Max output range in the O/H, Min output range in the O/L. If you want to use only ON/OFF control,
you can put the number of P.I.D zone into Temp. & Humi. A/T GAIN on the above in the left side is a constant
value which is applied to the each item of P.I.D during P.I.D carries out on operation. The setting range is from
0.0 to 10.0 (Initial value : 1.00). It is used that optimize P.I.D numerical value automatically operated after P.I.D
Auto-tuning more delicate manually. According to the variation of A/T GAIN value, the variation of Control feature
is same with [Fig. 104].
