dear robot community,
i study product design and recently i bought a kuka kr15 robot with krc1 cabinet.
after some problems in the beginning (had to change the capacitors on the mainboard) the robot runs but sometimes it stops and says "data cable a6 defect" and "motor temperature a6". after it stopped i cant run the robot any more. sometimes i can quit this error after a few minutes, sometimes after a few hours and sometimes after a day. sometimes it occurs 10 minutes after i started the whole system when the motor is definitely not hot. it seems like this occurs pretty random...
i already changed the cable with the a5 cable but its still the same. so it cant be the cable...
maybe the temperature sensor?
did anybody here also had this problem before?
best,
matthias
