■Using programs
Auto tuning is implemented using the following procedure.
1.
Setting each data in the temperature control module
Set each data. (Page 36 Settings related to the auto tuning)
2.
Operation mode setting
• Turn OFF→ON 'Setting/operation mode command' (Un\G399, b1). (Page 126 Setting/operation mode command (b1))
• Check that 'Setting/operation mode status' (Un\G398, b1) is ON. (Page 124 Setting/operation mode status (b1))
3.
Starting auto tuning
Turn OFF→ON 'CH1 Auto tuning command' (Un\G399, b4). (Page 127 Auto tuning command (b4 to 7))
4.
Implementing auto tuning
'CH1 Auto tuning status' (Un\G398, b4) is ON. (Page 125 Auto tuning status (b4 to 7))
5.
After the completion of the auto tuning (setting PID constants)
'CH1 Auto tuning status' (Un\G398, b4) turns OFF and calculation values are set in the buffer memory. (Page 36 Storing
the calculation values after auto tuning)
6.
Temperature control using the set PID constants
The temperature control is implemented with the set PID constants.

4.12 Auto Tuning Function
5.
The parameter is added in "View".
6.
Click the [OK] button.
7.
Write the set value to be changed.
8.
Set "Setting/Operation mode
command" to "1: Operation mode
command".
9.
Set "Auto tuning command" to "1:
ON".
10.
Set "Auto tuning command" to "1:
ON", "Auto tuning status" becomes
"Implementing" and the auto tuning
starts.
11.
When the auto tuning is completed,
"Auto tuning status" becomes
"Stopped".
12.
The temperature control is
implemented with the set PID
constants.
