(d) The temperature process value (PV) is not within the temperature measurement
range
Self-tuning is not executed. In addition, CH Self-tuning disable status (b8 of Un\G575, Un\G607, Un\G639,
Un\G671) turns 1 (ON).
(e) The value set in CH Output variation limiter setting (Un\G44, Un\G76, Un\G108,
Un\G140) is not 0 ( Page 112, Section 3.4.2 (20))
Self-tuning is not executed. In addition, CH Self-tuning disable status (b8 of Un\G575, Un\G607, Un\G639,
Un\G671) turns 1 (ON).
(f) CH AUTO/MAN mode shift (Un\G50, Un\G82, Un\G114, Un\G146) is set to MAN (1)
( Page 117, Section 3.4.2 (26))
Self-tuning is not executed. In addition, CH Self-tuning disable status (b8 of Un\G575, Un\G607, Un\G639,
Un\G671) turns 1 (ON).
(g) Values other than 0 (0.0%) have been set for the setting change rate limiter
( Page 119, Section 3.4.2 (28))
If the values other than 0 (0.0%) have been set to the following buffer memory areas, CH Self-tuning disable
status (b8 of Un\G575, Un\G607, Un\G639, Un\G671) turns 1 (ON).
(h) The heating-cooling control has been selected for the control mode ( Page 299,
Section 6.2)
The self-tuning is not executed.
(7) Discontinuation of self-tuning
The following operation during self-tuning discontinues the self-tuning operation.
The setting in CH Self-tuning setting (Un\G574, Un\G606, Un\G638, Un\G670) has been changed to Do
not run the ST (0).
The self-tuning operation in process is discontinued and self-tuning is not performed anymore after that. (An error
does not occur.)
Whether self-tuning is being executed can be checked in CH Auto tuning status (Xn4 to Xn7). ( Page 52,
Section 3.3.2 (5))
