Hi,
I bought a Kuka KR 30-3
Serial nummer 765138
Build 2009 got an update in 2011
Controller (v)KRC ed 05
Our problem is an Error 220 appear unexpectedly very often.
We have to reset the safety board.
We replaced everything but to no avail, a serviceman from Kuka Belgium did the job but didn't find the fault.
In automatic mode we have no problems at all.
Is there anybody out there who can solve the problem.
We have to wait till the intermediate circuit is discharged.
All help is welcome.
Henk Netherlands.
