Description
This bit turns ON after PID constants are corrected by the
self-tuning.
This bit turns ON after the simultaneous temperature rise

parameters are corrected by the self-tuning.
(Not used)
This bit turns ON when the self-tuning was not able to be
executed.

Condition in which the bit turns OFF
This bit turns OFF after one of the following operations is
executed.
• When 'Setting/operation mode command' (Y1) is turned
from ON to OFF and the mode shifts to the setting mode
• When 'CH1 Unused channel setting' (Un\G502) is set to
Unused (1)
• When 'CH1 PID control forced stop command' (YC) is
turned from OFF to ON
• When 'CH1 Self-tuning setting' (Un\G548) is set to Do
not execute ST (0)
This bit turns OFF in the following cases as well.
• When the self-tuning has started by the change of the set
value (SV)
• When the temperature process value (PV) becomes out
of the stable state and the vibration ST has started

This bit turns OFF after one of the following operations is
executed.
• When 'Setting/operation mode command' (Y1) is turned
from ON to OFF and the mode shifts to the setting mode
• When 'CH1 Unused channel setting' (Un\G502) is set to
Unused (1)
• When 'CH1 PID control forced stop command' (YC) is
turned from OFF to ON
• When 'CH1 Self-tuning setting' (Un\G548) is set to Do
not execute ST (0)
This bit turns OFF when all the conditions that disable the
execution of the self-tuning are cleared.
For conditions that disable the execution of the self-tuning,
refer to the following:
