Frozen pendant

    I have a Fanuc robot I am fighting with a frozen teach pendant. Some fat fingered line 8 into this program and every time the machine gets to this line of code it freezes the pendant. there is no error, the robot keeps moving and welding but the moment you try to edit the program (to delete the line) it freezes the pendant and you can't do anything until you cold start the robot. I've tried switching pendants but the same thing happens. There's also "???" at the end of the line and I don't know what these means or how's its possible. How can you delete this line so it stops freezing the pendant?


    Thank you.

    Approved the thread.

    This company has not backed up their machines in quite a few years. I've thought about creating a new T_CLEAN program. but this call routine is in multiple programs. If I create a new routine and name it the same and delete the original, will the new routine be executed in all programs?

    Fanuc doesn't have any sanitizacion check of code like ABB has, so if you delete or rename a routine, no error will show until the program reach the call. If program has a different name than the originally called or it does not exist, it will fault and program will be aborted.

    So yes, you can rename your old T_Clean routine, create a new one and put the same name it had, then you can either try to copy all instructions to the new routine or create it from scratch.

    If you copy the logic and points I suggest you to do it in two steps, copy all the code before that point, paste it on your new routine, then copy the lines after that point and paste them. Ignore that point that has the "???", create a new point and touch up (ensure the correct tool and frame is selected before doing the touchup so later it doesn't fault because tool/frame mismatch)

    If pendant still freezes while renaming the program, or while copying the lines, you may be able to delete the movement and the declaration by exporting it on .LS format so you can edit it on a text editor if your robot has the ASCII upload option (also delete the point from the point declaration located at the end of the file) or you can try to load the TP module into a virtual controller using roboguide, delete the line and then export it again on .TP format.
