 Changing control response with Fine tuning
After suitable PID values are calculated and stored by Autotuning or manual PID setting, the Fine
tuning allows you to change the control response of the same PID constant control. The control
response can be changed from fast to slow by simply changing the Fine tuning setting (6 levels: −3
to +3) in Parameter setting mode while the PID constant is unchanged.
For details of the Fine tuning, refer to 6.4 Fine Tuning (P. 6-17).
• Fine tuning setting
[Example: To slow the response (when “-1” is set)]
1. Press and hold the key for 2 seconds or more at the PV/SV monitor screen to go to the
Parameter setting mode, and press the key to display the Fine tuning setting screen.
2. Next, press the key to change the number of the flashing digit. Press the key to store the
new value.
If the set value of Fine tuning is returned to “0: Unused,” Fine tuning correction will be
turned off.
