Hi All,
I'm working with a XRC motoman UP6 robot. Over the past few weeks I've been getting the following alarm repeatedly:
Alarm 0901: watchdog timer error (XCP02#1) [1]
The alarms list manual says one should check the XCP02 board, remove, clean the connectors. If this doesn't help the board should be replaced. After I clean everything our robot would run for anything from a few days till 2 weeks without the watchdog error.
I recently replaced the board with a brand new XCP02 board. The robot worked fine for a few days, then the dog bit back again In the meantime I've also removed and cleaned the XCP01 board and board rack, had no luck there.
Now I'm assuming the next thing that might be faulty is the XCP01 board or board rack. Id like to replace them one by one until the problem is sorted, but these components aren't cheap.
Any advice would be much appreciated
Regards
