4.20 Simultaneous Temperature Rise Function
(d) Stopping of calculation for the simultaneous temperature rise parameter
Some characteristics of a controlled object do not lead to the optimum simultaneous temperature rise
parameter. In addition, an abnormal termination of self-tuning causes the temperature control module to stop
the calculation processing. For the conditions of an abnormal termination of self-tuning, refer to the following.
Page 231, Section 4.18 (8)
(e) How to set the simultaneous temperature rise parameter using self-tuning
Select one of the following setting values in CH Self-tuning setting (Un\G574, Un\G606, Un\G638, Un\G670).
