(d) The temperature process value (PV) is not within the temperature measurement
range.
The self-tuning is not executed. CH Self-tuning disable status (b8 of RWr14 to RWr17) turns 1 (ON).
(e) The value set in CH Output variation limiter setting (address: 107H, 137H, 167H,
197H) is not 0.
The self-tuning is not executed. CH Self-tuning disable status (b8 of RWr14 to RWr17) turns 1 (ON).
If the setting value is not 0, refer to the following.
Page 323, Appendix 3 (11)
(f) CH AUTO/MAN mode shift (address: 113H, 143H, 173H, 1A3H) is set to MAN (1).
The self-tuning is not executed. CH Self-tuning disable status (b8 of RWr14 to RWr17) turns 1 (ON).
If the setting is MAN (1), refer to the following.
Page 332, Appendix 3 (22)
(g) Values other than 0 (0.0%) have been set for the setting change rate limiter.
If the values other than 0 (0.0%) have been set to the following remote buffer memory areas, self-tuning is not
executed. CH Self-tuning disable status (b8 of RWr14 to RWr17) turns 1 (ON).
Remote buffer memory area name
CH Setting change rate limiter/Setting change rate limiter (temperature rise)
CH Setting change rate limiter (temperature drop)
If the setting value is other than 0 (0.0%), refer to the following.
Page 325, Appendix 3 (13)
(h) The heating-cooling control has been selected for the control mode.
The self-tuning is not executed.
If the heating-cooling control has been selected, refer to the following.
Page 311, Appendix 3 (3)
(7) Discontinuation of self-tuning
The following operation during self-tuning discontinues the self-tuning operation.
• The setting in CH Self-tuning setting (address: 2C0H to 2C3H) 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 (RX20 to RX23). (Page
