(0)  Hi, I have the same alarm on my 840Di, 400260, I've changed the panel and the error appeared again, if I install the ghost back-up it works if I've choosed to load from hard disk the parameters, if I tried from MCI I get the alarm, the voltage is 24.4 V, After power off the machine works only for few minutes. Please help, === Edited by Blue Moderator @ 8/10/2012 9:40 PM [GMT ] === Splitted from SINUMERIK 840D with 400260 alarms and renamed

Loading the Ghost backup for this alarm is not the right suggestion for this... Regards, Prakash Please no technical questions by Private Message(PM), use the FORUM!!!!!

(0)  The sinumerik is installed on a punching machine, all drives are working fine no error, I bought the MCP from siemens not from the producer of the machine, the person that sold it told me that I only need to configure the switches as on the last one, nothing else ... That is what I did, started the machine with the new one, the buttons stopped blinking and it was OK for few seconds, and after that ...same thing... I've used the ghost image after with the new panel and it was working like this for 2 shifts, and then after a break of half an hour ... started fine, made the program reference for the clamps ... and went blinking again ,....

Battery voltage should be around 3.6V..lithium battery... try connecting your Simatic Step 7 tool and check in the PLC why are you getting this error in the diagnosis.
