AT cycle (1. ATC, 2. ATC)
The number of ON/OFF cycles is selected when the Autotuning (AT) function is executed.
Data range:
0: 1.5 cycles
1: 2.0 cycles
2: 2.5 cycles
3: 3.0 cycles
Factory set value:
Input 1_AT cycle (1. ATC): 1
Input 2_AT cycle (2. ATC): 1
Related parameters:
PID/AT transfer (P. 101), AT action (P. 96)
Example: When the AT cycle is set to 1.5 cycle and the Autotuning (AT) function is
executed just after the power is turned on.
