MAINTENANCE OF
SERVO MOTOR
169
Make the following checks before starting operation, or once a week or
month.
(1) Vibration or abnormal noise
Check the servo motor for abnormal vibration or noise in the
following statuses:
D While stopped
D During low--speed operation
D During acceleration or deceleration
If any abnormal vibration or sound is detected, contact a FANUC
service station.
(2 ) External damage
Check the motor cover (red plastic cover) for cracks and the motor
surface (black--coated) for any abnormalities.
If any cracks are found, perform repair immediately. Alternatively,
replace the motor. If you have any questions about the replacement,
contact a FANUC service station.
(3) Dirt
Check the motor surface, screw indentations, and other places for oil
or coolant build--up.
Oil or coolant fouling on the surface causes a chemical reaction that
affects the coating, ultimately resulting in failure. Wipe away the oil
and coolant regularly.
If extensive fouling i s noted, determine how the oil or coolant is
reaching the motor. Take appropriate action to protect the motor from
the oil or coolant. For example, fit a cover.
