Hello,
A customer is using the FB IL_TempControl, to control the temperature of a welding for plastic containers.
The problem is that we have followed the manual and we have made the graph to obtain the data of Ks, Ts and Tt. Attached graph:
When starting AutoTune with these values, after a few seconds it gives a "Calculation error" error and we have no further diagnosis.
Any idea what parameter or value might be wrong for AutoTune not to work?
Thanks in advance.

Hard to say ...
Please have a look in the manual https://docs.automation.boschrexroth.com/doc/172933738/il-tempcontrol/1-07/en/ and there in the chapter "Information on specific errors" ...:

I think there are some possibilities here in identification.
In particular, the temperature control system is a nonlinear system with a large delay time and a large response time, and it is difficult to identify it. So it is hard to calculate if we use the linear transfer function to fit or if the data quantity is worse.
