(5) Simultaneous temperature rise AT
PID constants and the simultaneous temperature rise parameter are calculated. The waveform upon execution is
the same as that for the auto tuning function.
For details on the auto tuning function, refer to the following.
Page 176, Section 4.6
(a) How to execute the simultaneous temperature rise AT function
Follow the instructions below.
1. During the setting mode (Setting/operation mode status (Xn1): off, set CH Simultaneous
temperature rise AT mode selection (Un\G733, Un\G749, Un\G765, Un\G781) to Auto tuning for
simultaneous temperature rise (1). ( Page 155, Section 3.4.2 (83))
2. Turn off and on CH Auto tuning instruction (Yn4 to Yn7).
3. Set the module to the operation mode (turn off and on Setting/operation mode instruction (Yn1).
(b) Operation with the simultaneous temperature rise AT function
After the procedure described on Page 242, Section 4.20 (5) (a) is executed, the Q64TCN operates as
following.
Operation of the Q64TCN
1
CH Auto tuning status (Xn4 to Xn7) is turned on. Then normal auto tuning is performed and the simultaneous
temperature rise parameter is calculated.
2
The calculated value is stored in the buffer memory when the simultaneous temperature rise parameter is normally
calculated. In addition, CH AT simultaneous temperature rise parameter calculation completion (b0 of Un\G573,
Un\G605, Un\G637, Un\G669) is turned 1 (ON). After auto-tuning is completed, CH Auto tuning status (Xn4 to
Xn7) is turned off and the module is shifted to the PID control.
