Auto Tuning
2.1
Once AT set ‘YES’, auto tuning is to be performed.
2.2
After auto tuning finished, PID parameter is to be set automatically.
2.3
ATVL = auto tuning offset, and it will be deduced from SP.
(It prevents over-shooting during auto tuning)
SP-ATVL = Auto-tuning value, ATVL = Auto tuning offset
Ex.) SP = 200
°
C, ATVL = 5, Auto tuning point is at 195
°
C
* ATVL means auto-tuning point (195
°
C) in program type model
2.4
Auto tuning failure
2.4.1 ATVL is too big
Æ
If no sure, set ATVL = 0)
2.4.2 System time is too long.
Æ
Set PID parameter individually.
