I am in process of putting a kuka kr200l170 to work.
Cabinet (V)KRC2 ed05 No se série 37113 22/2005
with pc KPC ed05 NO serie 00164 35/2008.
In the process already add some i/o and 7 axis, SPs programming and it is working nice.
Process -> My new used kuka KR200L170 comp
When finaly everything is working nice two errors appeared:
1052 KCP: CAN bus error
328 KCP: connection error Watchdog_error
If i let the robot dormant with power off some time, when i power it up it boot good and i can work for 5 or 10 or 15 minutes then screen light goes 40% or 50% off with little grey noise and errors appear, and softkeys stop working.
When the error appear i can't acknowledge the error. The error dont disapear.
If i power it down and up without wait the robot doesn't boot good.
It boots already with reduced light in the LCD and with the error already in the mesages that i can't acknowledge.
What i already DO:
I already check for continuity of every single wire of the cable that connect the pendant (OK) and if have short with another wire of same cable (OK).
Already checked the fuses. They are ok with the values inside the cabinet.
Already put the robot to work with another spare and good PSU same problem.
Safety circuit X11 it is ok as i dont have any right now, only jumpers.
Checked the voltage that goes to PC X961 i get 26.5V (same when is working and not working)
Already changed the 2 robot batteries 12v 4,5A.
I am not sure about the place where i can measure the voltage that goes to pendant.
Some wint what i can do ? to start ?
