All the drives are connected to Simotion D435 and two control extentions. The crane has been commissioned on dec 2012. Now a days some faults which are coming frequently in drives specially when the crane is not working/stand by mode(approx. 6-8 hrs after operation). The faults are: Lower trolley cross travel-30885,30889,35851,30008,etc Lower Trolley Aux.Hoist-1380,35851,Cylic data transfererror,35887,speed controller enable missing,etc Upper Trolley MH1-30027,etc Upper trolley cross travel-30008,35851,31885,3360,etc After fault occurs we do only power recycle and the respective drives becomes healthy. What to do?

EMC problems For case 1 you can try to increase the 24V supply to have a better reaction when the 24V is oscillating because of the machine usage / state. If this doesnt work try to check the EMC quality of your connections. And if this is ok then i would suggest to contact the hotline.
