2) _ATxx_T_s (Auto-tuning xx Loop operation cycle)
It sets/indicates the operation cycle of ‘xx’ th loop auto-tuning. The available scope is 100 ~
65,535.
3) _ATxx_MV_max, _ATxx_MV_min(max. MV, min. MV)
It sets max. MV and min. MV of ‘xx’ th loop respectively. If the max. MV is set lower than min.
MV, the auto-tuning loop generates an error and does not work.
4) _ATxx_PWM (AT output junction setting)
It sets the junction that PWM output of ‘xx’th loop is output. The PWM output junction is valid
only between H’20 ~ H’3F (hex). If any other value is entered, PWM output does not work.
5) _ATxx_PWM_Prd (PWM output cycle setting)
It sets the PWM output cycle of ‘xx’ th loop. The available scope is between 100 ~ 65,535 at the
unit of 0.1ms.
6) _ATxx_HYS_val (Hysterisis setting)
It sets the hysterisis of ‘xx’ th loop. For more information about hysterisis function, refer to 6.3.3
Auto-Tuning Parameter Setting. If it is set as 0, it does not work.
7) _ATxx_STATUS (Auto-tuning status)
It indicates the auto-tuning status of ‘xx’ th loop. If auto-tuning is in operation, it is 1;
if completed, it is 128. In any other cases, it shows 0.
