txturbo Posted December 31, 2014 Share Posted December 31, 2014 I am having a problem with autotuning. When I start the autotune process on my PID loop the PV just stops. it never moves. Is there a set of conditions that needs to be met for the autotune process to work? Thanks... Link to comment Share on other sites More sharing options...
AzeoTech Posted December 31, 2014 Share Posted December 31, 2014 Its important to remember to set the Step Size parameter and that this is the change in Output, not SP. My guess is that you have this value at 0 or just too low. Link to comment Share on other sites More sharing options...
