Meaning of auto-tuning (AT) start in auto-tuning Group(G.At) is as follows:
1 is auto-tuning for SV1.
2 is auto-tuning for SV2.
3 is auto-tuning for SV3.
- AUTO proceed with the Auto-tuning in the order of the SV1, SV2, SV3.
Function Description
Function 1 : Auto-tuning
Auto-tuning is a function that the controller automatically measures the characteristics of
the target system and calculates the optimal values for proportional band (P), integral time
(I), and derivative time (D) and then sets the optimal values for each PID parameters.
During auto-tuning, the control output is changed to ON/OFF control to get response from
the target system. From the response, the most appropriate PID values are obtained for
the system. This is called " Limit Cycle".
HX series has two types of auto-tuning : standard type and low PV type.
① Standard auto-tuning : This auto-tuning is based on the set value (SV).
② Low PV auto-tuning : This auto-tuning is based on the value 10 % lower than the set
value (SV).

※ Please note that frequent communicational data recording may exceed life of EEPROM
and cause malfunction.
If you want to use the auto-tuning, there are 2 ways:
1. When you select the number for set value(SV) you want in start auto-tuning(AT)
of auto-tuning Group(G.At), auto-tuning will start.
2. After selecting auto-tuning(At) in hot-key(Hk.SL) of control group(G.At), auto-tuning will start with
pressing hot-key(SET + UP) in the operation mode of controller for 3 seconds and auto-tuning
will stop with pressing hot-key(SET+UP) for 3 seconds.
Note: When auto-tuning(AT) runs, 'AT indicator' flashes at the front panel.
(When manual output is 'ON', 'AT indicator' lights on steady at the front panel.)
