Autotuning fails with error code "Autotune-Cannot to find 20% Temp", what is "Temp"?
My system is an Peltier testsystem and PT100 element
Here are my program calls:
there is an older application note which covers auto-tuning quite well.
Taking it at hand and running the auto-tuning you should be able to identify when
the issue arises and take countermeasures as stated there.
Yes i have read that and the Application Note but i still get the error code that autotune can't reach 20% Temp, but i don't know what "Temp" it's trying to reach?
If i have start temp e.g. 24.5 C is it trying to reach 20% of that 4.9 C?
here is an excerpt from the programming example
send (kth2510AT, “:sour:temp:atun:start 25”, status) ‘25C start temp
send (kth2510AT, “:sour:temp:atun:stop 30”, status) '30C temp setpoint.
Here you can see that a start and a stop temperature is used, the difference is a 100 % step.
