5.1 Operation of Controller
5-10
<4>
Derivative Time Setting
Function
Sets the derivative time used for PID control.
Set with [
▲
] or [
▼
] key
Setting range
0 ~ 3600 sec.
If “0” is set, derivative control is disabled.
C

SV
Initial value
0sec
<5> Heating Proportional Cycle Setting
Sets heating proportional cycle.
Set with [
▲
] or [
▼
] key
Function
If the proportional cycle is set at 2 sec.
and Heating Output is 70%, the output will
be 1.4 sec. ON and 0.6 sec. OFF.
Setting range
1 ~ 120sec.
C
SV
PV
Initial value
1sec.
<6> ARW setting
Sets anti-reset wind-up.
Set with [
▲
] or [
▼
] key
Function
Reduces overshoot in PID control due to
integrating operation. The integration
operation is not performed above the set
value. The set value must be higher than
the output for stable control.
C

PV
Setting range
0.0 to 100.0 %
Initial value
100.0 %
<7> Cooling Proportional Band Setting
Function
Sets the proportional band for cooling.
Set with [
▲
] or [
▼
] key
Setting range
0.10 to 10.00 times
C
SV
PV
Initial value
0.50 times of P1 set value.
<8> Cooling Proportional Cycle Setting
Sets cooling proportional cycle.
Set with [
▲
] or [
▼
] key
Function
If the proportional cycle is set at 2 sec. and
Cooling Output is 70%, the output will be 1.4
sec. ON and 0.6 sec. OFF.
Setting range
1.0 ~ 120.0 sec.
