Fanuc SERVO-067 OHAL2 alarm - over temperature. How difficult to change motor ?

Good Afternoon ,

A co-worker is having a problem at the plant with a Fanuc robot and a Robot Alarm SRVO-067 OHAL2 alarm (Grp:%d Ax:%d) Fault . If the motor needs to be replaced , how difficult is it to be calibrated . I guess just single axis calibration would work ? It's not that hot in the plant according to him .

Thanks always for your help .

No, it needs to be a full cal. I always call Fanuc in to do the repair any calibration.
