KUKA ROBOT SYSTEM ERROR: 'Dynamic brake active' error code 108

[WoodenYang]

Hello,

I have met a problem with kuka Krc4 robot. When the robot running in automode, it will stop randomly with 'Dynamic brake active' message(Error code 108). After robot stopped, this error message will disappear but recorded in error history log. I need to switch plc's mode so that the error can be cleared. Doesn't any one knows why this error happened and how to solve it?

If the error is caused by the _robotState.StopMess signal, then this is definitely a problem on the robot side...

Programming a workaround on the PLC side only eliminates the effects - not the cause of the problem...

That's why I would contact Kuka support again....
