Hello everyone!
I'm working on two Fanuc S-420FD robots with their old R-J Controllers and one of them lost the program due to lack of battery in the CPU. We are trying to copy the system from one to the other. We bought the "base" for the memories and two 2MB memories, according to the manual. Following the steps in the manual, we first copy FROM and everything works fine but we can not complete the CMOS copy. It gets locked in the message "Calculating checksum. Please wait..." for up to 6 hours!
Has anyone done this and had the same problem?
Should I leave processing more hours? Is it normal to take so long?
We've tried a lot of things. Change the position memories, copy the CMOS first, try with only one memory in the slots, and others.
Here is a picture of the display and memory system mounted on the controller.
Thanks and any help is welcome!
