 Control algorithm (Settings: PID/FUZY/SELF)

[Description]

• This parameter is used for selecting PID control, FUZZY-

PID control, or PID control with self-tuning.

• To select the PID control or FUZZY-PID control, it is

necessary to set the parameters of  ,  , , and 

manually or by the auto-tuning in advance.

[Setting example] Changing the control system from PID to FUZZY

Press and hold the 

SEL

 key for three seconds.

 will be displayed on the PV display.

Press the 

 key to display 

 .

Press the 

SEL

 key once.

The current setting ( 

 ) flashes on the SV display.

Press the 

 or 

 keys to display 

 .

Press the 

SEL

 key once.  

 will stop flashing and will be registered for 

.  After that, the

controller will operate with the FUZZY control system activated.

If you want to display the operation status, press and hold the 

SEL

 key for two seconds.

• For the ON/OFF control (Two-position control), select

the PID control and then set    to 0.0.  For detailed infor-
