■When using a program
The auto tuning is executed by the following procedure.
1.
Setting each data in the temperature control module
Set each data. (Page 39 Settings related to the auto tuning)
2.
Operation mode setting
• Turn from OFF to ON 'Setting/operation mode command' (Y1). (Page 164 Setting/operation mode command)
• Check that 'Setting/operation mode status' (X1) is ON. (Page 157 Setting/operation mode status)
3.
Starting the auto tuning
Turn from OFF to ON 'CH1 Auto tuning command' (Y4). (Page 165 Auto tuning command)
4.
During auto tuning
'CH1 Auto tuning status' (X4) is ON. (Page 159 Auto tuning status)
5.
After the completion of the auto tuning (setting PID constants)
'CH1 Auto tuning status' (X4) turns OFF and calculation values are set in the buffer memory. (Page 39 Storing the
calculation values after auto tuning)
6.
Temperature control with the set PID constants
The temperature control is executed with the set PID constants.
