Problems with 100% Autotuning (AT-2)
If autotuning at 100% (AT-2) does not produce the desired results, you can also execute autotuning at
40% (AT-1).
●Autotuning at 40% (AT-1)
A 40% variation in the manipulated variable of the limit cycle is used for autotuning. Executing 40%
autotuning may require more time than executing 100% autotuning (AT-2).
The limit cycle timing varies according to whether the deviation (DV) at the start of autotuning execution is
less than 10% FS.
