How to diagnose position deviation alarms on a FANUC R-2000iC / R-1000iA robot
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.
How to diagnose servo joint alarms on a FANUC R-2000iC / R-1000iA welding robot
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.
How to manage spot welding electrode wear on a FANUC R-2000iC / R-1000iA robot cell
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.
