FANUC R-2000iC / R-1000iA

Position deviation alarms indicate the robot arm is not reaching the commanded position. Check for mechanical interference, verify the zero position mastering, and inspect the speed reducer before calling FANUC service.

FANUC servo joint alarms are usually caused by overload from incorrect payload settings, brake failure, or pulse coder errors. Read the alarm number on the Teach Pendant first before touching hardware.

Worn spot welding electrodes cause weld splash, small nugget size, and surface indentation on the visible side of the car body. Dress electrodes on a schedule rather than waiting for weld quality to degrade.
