■Operation of the simultaneous temperature rise AT
When the function is executed, the temperature control module operates as follows:
Operation of the temperature control module
1 'CH1 Auto tuning status' (X4) turns ON The normal auto tuning is executed and the simultaneous temperature rise parameter is calculated.
2 A calculation value is stored in the buffer memory when the simultaneous temperature rise parameter has been properly calculated. CH1 AT
simultaneous temperature rise parameter calculation completion (Un\G413, b0) is turned ON. After the auto tuning is completed, 'CH1 Auto tuning
status' (X4) turns OFF and the module is shifted to the PID control.
