Hi everybody. Very nice forum you have here. I scanned through all 44 pages of posts and did not see any resolution for my problem.
My robot has been running in my shop for many years but just a week ago it started throwing errors.
alarm 0021 communication error (servo) [50] occur times:1
alarm 1302 communication error (servo I/O) [5] occur times:1
alarm 4208 system error (arith) [1] occur times:1
I turn off the robot and leave it to cool off for a few hours. The error has not occurred when the robot is cold.
Sometimes it will not throw any error, it will simply just stop in its tracks. One time I took over with the pendent and tried to get it to movj to a safe location and it started going to some other location than what was programmed. But after letting it set for a day it was OK again.
I only have this one robot in my machine shop. I set it up in a polishing sell to buff small metal parts.
Anybody have any ideas what I should do next?
Cheers
Dave
