Hi to all, We have a problem with one of our pumps in our plant. Pump is controlled via PID regulator in TIA portal. We are producing alloy wheels, and we have a problem with pump which task is to deagrease wheels on conveyor carriers. Problem is when we start our production and if wheels are at conveyor carriers near the pump nozzles, maximum overshot pressure of the pump is 4 bar and this pressure knocks the wheels from the carriers. Our final value of pressure is around 2 bar (this value need to be reached and when we have this pressure everything is fine). We are forced to manually start the pump (we change the state on SINAMICS G120P from AUTO to MANUAL and set the value) to avoid this problem. PID parameters are in the attachments. We checked our SINAMICS G120P and it seems normal and we don't know what to do anymore. I hope someone have idea how to resolve this problem. Thanks in advance!
