When channels are divided as following:
Ex.
• CH1 and CH2: Group 1
• CH3 and CH4: Group 2
CH□ Operation monitor
CH1 Simultaneous temperature rise status (RX24)
CH2 Simultaneous temperature rise status (RX25)
CH3 Simultaneous temperature rise status (RX26)
CH4 Simultaneous temperature rise status (RX27)
*2
This becomes Simultaneous temperature rise in process (1) when the temperature rise starts; however, it becomes
Simultaneous temperature rise not in process (0) before the temperature rise starts.
● When using the simultaneous temperature rise function, turn on CH Operation request flag (RY11 to RY14) for the
corresponding channels simultaneously.
● When the simultaneous temperature rise function is used, the setting change rate limiter cannot be used. (Page 324,
Appendix 3 (12))
● When the operating status is changed from stop to run during a simultaneous temperature rise, the simultaneous
temperature rise function stops working and CH Auto tuning status (RX20 to RX23) turns off. (No error occurs.)
