2.4 Safety precautions for using motors
The Delta AC servo motor is designed for industrial applications. It is necessary that you fully
understand the motor specifications and operation manual. For your safety and correct use,
please carefully read the manual, specifications, and precautions for the motor before connecting
the motor to any equipment.
The safety precautions are as follows:
Handling, mounting, and storage

When removing or installing a servo motor, please hold the whole motor instead of holding
the cable or only the motor shaft.

Do not hit the motor shaft. Impact force will damage the encoder that is attached at the rear
end of shaft.

Keep the axial or radial load within the allowable range listed in the specifications.

The shaft of servo motor is not water- or oil-proof. Do not use, install, or store the servo
motor in a humid environment that contains water, oil, corrosive gases, or liquids.

The material of motor shaft is not rust-proof. Although the rust-proof oil has been applied to
the shaft during the manufacturing process, you must check the shaft condition and apply
rust-proof oil every three (3) months if storing the motor for more than six (6) months.

Ensure that the environmental conditions for storing the servo motor conform to the
specifications in the instruction sheet.

The encoder attached to the motor is easily damaged; please take the necessary steps to
avoid electric interference, vibration, and abnormal temperature changes.
Wiring

If the current exceeds the maximum current in the Specifications, the internal parts of the
motor may lose their magnetism. Please contact the distributor or local Delta sales
representative if this problem occurs.

Please check that the motor wiring and the voltage of the motor brake are correct.
Also, make sure that the wiring of the encoder signal and power cables is correct.
Incorrect wiring will lead to abnormal operation of motor, malfunction, or damage.

To avoid capacitive coupling and noise, isolate the motor power cable from the encoder
power and signal cables. Do not connect them to the same circuit.

The AC servo motor must be correctly grounded.
