HI! So glad to be here.I'm working at a BIW line with about 20 kuka krc4 robots. most of them are used to conventional resistance welding.of course the line has worked for 2 years.
Recently,I found a small annoying problem only in welding.Due to the STOP1 like safety gates ,The robot and external axis servogun E1 are stopped. but !!!one of the robot which gun is C is always out of the path.after resuming the line ,it still doesn't move only after executing BCO in T1 and we'll just see the E1 axis moving....why only this robot happened?I was wondering if it has a larger move range?The open limit is about 150mm.but there has a same one that happens up to one welding error dialog.then we can select YES to reweld....I can't figure it out...any of your tips and help would be appreciated.
btw.there are relevant opt versions:
KRC version is 8.3
Servogun TC version is 4.1.5
