(8) Conditions where self-tuning does not complete due to errors
The following operations and conditions cause an abend of self-tuning. At the abend, CH  Self-tuning error (b10
of RWr14 to RWr17) turns 1 (ON).
• When 6000s (1 hour and 40 minutes) or longer passes after the start of ST
• When the change rate of the temperature process value (PV) during ST is less than 1.125 (

/minute)
• When CH  Temperature process value (PV) (RWr8 to RWrB) is outside the temperature measurement
range (

Page 303, Appendix 2 (5))
• When the manipulated value (MV) does not reach the upper limit output limiter value or lower limit output
limiter value before the measurement is completed and necessary measurement data is not obtained
• When self-tuning is started with the starting ST and the temperature process value (PV) that is supposed to
rise drops by 1

) or more
• When self-tuning is started with the starting ST and the temperature process value (PV) that is supposed to
drop rises by 1

• When the setting for the remote buffer memory areas in the following table is changed during self-tuning
*1 Changing the setting causes an abend only during the activation of ST by start ST.
