Hi, Please excuse the length of this but I will try to explain my issue as well I can. I have a Handtmann 5 axis CNC machine with an 840D controller and a Simodrive 611 NC / PLC System with 8 drives attached. It is giving me problems where I cannot run as normal. There are three distinct situations. 1) I reference the machine then do a test stop the test stop gets to the end where the power goes out and it throws a stop event. 2) I reference the machine then do a test stop the test stop gets to the end where the power goes out and it gives me all sort of crosscheck errors but no stop event. 3)I reference the machine then do a test stop the test stop gets to the end where the power goes out and it does not throw a stop event. The machine will now run but when I turn the power off on the controller it will throw a stop event. I have attached screenshots and diagnostics buffers for each scenario. I am trying to pin this down but I am not that familiar with the diagnostics buffers. I have swapped out the NCU / PLC card and box and reloaded the software. Any help would be appreciated.

Hello Nick S, From the descrption & the PLC diagnostic buffer as well as alarm screen shot, it is clear that, the machine has lost safety data synchronisation with machine data. Without having detailed/complete information of machine & its problem diagnosis, user should never try with NC PLC data. Please contact the OEM or your nearest Siemens service support center to overcome this problem. |
