CAUTION
• Never use the products in an environment subject to water, corrosive gases, inflammable gases, or
combustibles.
Failure to observe this caution may result in electric shock or fire.
• Do not step on or place a heavy object on the product.
Failure to observe this caution may result in injury or malfunction.
• Do not cover the inlet or outlet ports and prevent any foreign objects from entering the product.
Failure to observe this caution may cause internal elements to deteriorate resulting in malfunction or fire.
• Be sure to install the product in the correct direction.
Failure to observe this caution may result in malfunction.
• Provide the specified clearances between the power regeneration converter and the inside surface
of the control panel and between the SERVOPACK and the inside surface of the control panel, and
keep both the converter and the SERVOPACK sufficiently separated from all other devices.
Failure to observe this caution may result in fire or malfunction.
• Do not apply any strong impact.
Failure to observe this caution may result in malfunction.
• Provide at least 100 mm between the machine and the side of the motor that is opposite from the
load (i.e., the side where cooling air is exhausted) to ensure sufficient flow of cooling air to the cool-
ing fan.
If there is not sufficient airflow, the motor temperature fault protective function may operate even at the rated
load.
• Do not allow water, oil, or other liquids to come in direct contact with the motor. If there is a chance
that water, oil, or other liquids may come into direct contact with the motor, install a protective cover.
If water, oil, or other liquids enter the motor, the resistance will be lowered and a ground fault may occur.
• Install the motor on a sturdy mounting bed, base, stand or other structure.
The weight of the motor and the dynamic load during operation are placed on the installation structure and
may cause vibration if the structure is not sturdy enough.
CAUTION
• Be sure to wire correctly and securely.
Failure to observe this caution may result in motor overrun, injury, or malfunction.
• Install the I/O signal cables and encoder cable at least 30 cm away from the motor’s main circuit
cable. Never place them in the same duct or bundle them together.
Placing these cables too close to each other may result in malfunction.
• The maximum wiring length is 3 m for I/O signal cables, 20 m for encoder cables or motor main cir-
cuit cables, and 10 m for control power supply cables (+24 V, 0 V).
• To extend the encoder cable past 20 m, always use an extension encoder cable.
• If the main circuit cable length of the servomotor exceeds 20 m, the voltage drop along the cable
will increase greatly and the intermittent duty zone of the torque-motor speed characteristics will be
reduced.
• Use twisted-pair shielded wires or multi-core twisted pair shielded wires for input/output signal
cables and the encoder cables.
• When you connect the cables, do not touch with your bare hands the motor connector pins or the
encoder connector pins that are provided with the motor.
Particularly the encoder may be damaged by static electricity.
• Take appropriate and sufficient countermeasures for each when installing systems in the following
locations.
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields and magnetic fields.
• Locations subject to possible exposure to radioactivity.
• Locations close to power supplies.
Failure to observe this caution may result in damage to the product.
• Wiring or inspection must be performed by a technical expert.
• Do not connect a commercial power supply to the U, V, or W motor connection terminals.
Failure to observe this caution may result in injury or fire.
