Hello,
Yesterday during testing simple welding instruction I got error TPU lost contact. It was during programming, teachpendant was in my hand and after robot finished simple welding instruction I put teachpendant on table to check weld. After I back there was that error and everything were blocked. I tried to switch off and start robot again but nothing. Leds on boards are red and nothing change during start up. Removing boards and battery for cold start didn't make any progress. I also put another DSQC 326 board but no help. What could be wrong with my robot, What I could try more to find issue? Will I get more info about issue if I connect robot to PC using hyperterminal?
Thank you for any help.
Regards.
