Hello guys, I would need your help to solve a problem. After changing a linear scale (measuring system with distance coded ref.marks) and referencing, we have error messages on the screen. [enclosed pictures] . It is not possible to move with Y axis . Going into menu of MD , we know that limits of Y axis are in a range of + 25.256mm and - 4.35mm . Switching off / on the machine does not help, the same screen is there. Thanks, vlado news : 1. after changing software limits (36100 , 110 ... ) we can move with axis only in one direction ( minus) 2. still not possible to reference the axis and get rid of actual value out of the limit range update : hello to all who will need it , as I have disribed , I could not get rid of the actual position of the Y axis which was out of the limits range. I changed a lot of MD regarding referencing , limits and so on - no success I did not understand , if the axis is not referenced . limits are not valid ( I read this in siemens manual and I also did some attemps with other axis to be sure it is the truth - it was ) Finally , we uploaded backup from a hard disk . I was affraid if it is a correct version... (file NCxxxxxxxx ) , it seemed it is the last backup stored in memory. After this everything was ok , the actual value jumped into limits range and we could do referencing. I'm not an expert , I ordinary do fixing hardware and I'm not familiar with parameters, software etc... I think , if there are some limits in PLC program , they can cause such problem if they are corrupted. Am I right? I do not know if somebody answer my question, due nobody has reacted so far in this thread... :-) This is strange for me, I would expect some reminder or warning regarding to PLC program in siemens manual that describes MD take care , Vlado AttachmentGmail.zip (245 Downloads) |
