I have 2 ERC/K6 package where the batteries have gone completely dead. I have replaced the batteries and done the normal routine to bring them back to life but am getting a Connection Error
"TB _CPU" on one of them and am unable to find any mention of this error anywhere.
Now I know they are old and before you suggest that I scrap them or "push them off of a cliff" please listen to my reason for trying to repair them.
Upon retiring in 2015 I donated a couple ERC-K6 packages to a local non-profit organization that rehabs young adults. Due to COVID, these machines have set idle for a while and the batteries went dead. They would like to get them back up and running and I volunteered to try.
I have replaced the batteries on both of them and one of them came back to life. The other is displaying the error mentioned above when the Maintenance / Parameters switch is in the center position and everything stops there. If I place the switch in the Param position and boot it will go into the default home screen. Everything looks normal and when I start the servos the contactor pulls in and the servos drives are not showing any errors but I do get a message "On-Line without initial check" and the servos are quiet and nothing will move. The Absolute data in the home position is either 0 or single digit positive numbers for all of the axis. This is true if I leave the switch is in the Param position or I switch it back to the center position after boot.
Any help would be greatly appreciated. Hopefully I provided enough information.
Thanking you in advance
Bob
