Using PID Control
You set this parameter in the Initial Setting Level. The parameter is set to ON/OFF control by default.
Step 2 Setting PID Control Parameters
1 Setting PID Control
Press the
(Level) Key for at
least 3 seconds.
Press the ( Mode) Key
several times to display cntl
(CNTL).
Change the set value with
the (Up and Down)
Keys.
←
cntl
(CNTL): Indicates the Control Method parameter.
←Default setting is onof (ONOF): ON/OFF control
Initial Setting Level
←in-t (IN-T) will be displayed to
show that the Initial Setting Level
has been entered.
Press the K ey for at least 3 seconds.

Self-tuning disabled. Use this setting to perform
autotuning or to set the PID constants manually.
Self-tuning enabled. Use this setting to perform

←
st
(ST): Indicates the Self-tuning parameter.
←Default setting is on (ON): Enabled.
You cannot set the following parameters while self-tuning (ST)
is enabled.
• Adjustment Level: MV Upper Limit, MV Lower Limit, SP
Ramp Set Value, and SP Ramp Fall Value
• Advanced Function Setting Level: SP Ramp Time Unit
* To set these parameters, first set the st (ST) (self-tuning)
parameter in the Initial Setting Level to off (OFF) to
disable self-tuning.
