in addition to the previous post - more details, I use invert logic for cooling. So when Tinside > Tsetp. PID responds, bigger error, bigger PID output, when error decrease, PID output also decreases and responds. But as soon as error = 0 , the PID output freezes , and just keeps some value not equal to 0. Seems like it goes in " hidden " inactive mode, but status output = 3 (for automatic). In this state, if I re-trigger "PID_Compact_2".sRet.i_Mode --> 0 --> 3 then PID wakes up again. I attach PID tech. obj. settings - not latest version, I also tried to remove Integral time with no effect. AttachmentPID_Compact_2_settings.pdf (610 Downloads) |
