■How to set vibration ST
Set the following value for "Self-tuning setting" in "Application Setting."
• 4:Starting ST plus Vibration (PID Constant Only)
Operation of self-tuning
The following shows the operations after the start of the self-tuning.
■When the temperature control is started or the set value (SV) is changed
1.
'CH1 Auto tuning status' (X4) is ON. (Starting ST) (Page 159 Auto tuning status)
2.
CH1 PID auto-correction status (Un\G411, b0) is turned OFF. (Page 237 CH1 Self-tuning flag)
3.
The temperature is controlled using the set PID constants.
4.
PID constants are calculated by the self-tuning.
5.
Check if the control response is poor or not.
If not, proceed to No. 8.
6.
The PID constants are changed to the ones calculated by the self-tuning.
7.
CH1 PID auto-correction status (Un\G411, b0) is turned ON. (Page 237 CH1 Self-tuning flag)
8.
'CH1 Auto tuning status' (X4) turns OFF. (Page 159 Auto tuning status)
9.
The temperature is controlled with the set PID constants.
■When the temperature control is not started or the set value (SV) is not changed
1.
Check if the temperature process value (PV) is out of the set value (SV) or not.
If not, proceed to No. 8.
2.
Check if the control response is oscillatory or not.
If not, proceed to No. 8.
3.
'CH1 Auto tuning status' (X4) is ON. (Vibration ST) ( Page 159 Auto tuning status)
4.
CH1 PID auto-correction status (Un\G411, b0) is turned OFF. ( Page 237 CH1 Self-tuning flag)
5.
PID constants are calculated and changed by the self-tuning.
6.
CH1 PID auto-correction status (Un\G411, b0) is turned ON. ( Page 237 CH1 Self-tuning flag)
7.
'CH1 Auto tuning status' (X4) turns OFF. ( Page 159 Auto tuning status)
8.
The temperature is controlled with the set PID constants.
