1.1 RECEIVING AND KEEPING AC SERVO MOTORS

When you receive an AC servo motor, make sure that:

• The motor is exactly the one you ordered, in terms of model, shaft,

and detector specifications.

• No damage has been caused on the motor.

Because FANUC inspects servo motors strictly before shipment, you

do not, in principle, have to inspect them when you receive them.

However, you should check the specifications (wiring, current, and

voltage) of the motor and detector carefully, as required.

The servo motors should be kept indoors as a rule. The storage

temperature range is -20 to +60°C. Do not place or install AC servo

motors in the place where:

• It is extremely humid and dew is prone to form,

• There is a steep change in temperature,

• There is constant vibration, which may cause damage to the shaft

bearings, or

• There is lots of dust and trash.

Page 62.FANUC SERVO MOTOR series SAFETY PRECAUTIONS B-65165E/02 2.1 WARNING - Be safely dressed when handling a motor. Wear safety shoes or gloves when handling a motor as you may get hurt on any edge or protrusion on it or electric shocks. - Use a crane or lift to move a motor from one place to another.
Page 7B-65165E/02 SAFETY PRECAUTIONS 2.FANUC SERVO MOTOR series - Connect power wires securely so that they will not get loose. A failure to observe this caution may cause a wire to be disconnected, resulting in a ground fault, short circuit, or electric shock. - Do not supply the power to the motor while
Page 82.FANUC SERVO MOTOR series SAFETY PRECAUTIONS B-65165E/02 - Be careful not get your hair or cloths caught in a fan. Be careful especially for a fan used to generate an inward air flow. Be careful also for a fan even when the motor is stopped, because it continues to rotate while the amplifier is tur
