INSTALLATION
Precautions
• Install the rotary servo motor on incombustible material. Installing them either directly on or near combustibles may lead to
smoke or a fire.
• Provide adequate protection so as to prevent conductive matter (such as screws and metal fragments) and combustible
matter (such as oil) from entering the rotary servo motor.
• The temperature of the rotary servo motor may exceed 100 °C depending on the operating method. Take safety measures
such as providing covers.
• The eyebolts of the rotary servo motor are only for transportation of the rotary servo motor.
• Do not use them to transport the rotary servo motor when it is mounted on a machine.
• Be sure to install the geared servo motor in the specified direction. Not doing so will cause oil leakage, which may lead to a
fire and malfunction.
• Do not overtighten the eyebolts of the rotary servo motor. To prevent damage to the tap, avoid tightening too hard.
• Do not stack in excess of the specified number of product packages.
• Do not carry the rotary servo motor by the cables, connectors, or encoder. Doing so may cause the rotary servo motor to
drop.
• When installing the rotary servo motor, follow the user's manual and install the motor in a place that can support its weight.
• Do not install or operate any rotary servo motor that is missing parts or is damaged.
• Securely fix the rotary servo motor to a machine. If attached insecurely, the motor may come off during operation.
• To prevent a connection failure, malfunction, or similar problem, do not strike the connector.
• Be sure to measure the vibration level with the rotary servo motor mounted on the machine. A great vibration may cause
early damage to a bearing, encoder, brake, and gear reducer, and poor connector connection or bolt looseness.
• For the gain adjustment at the equipment startup, check the torque waveform and the speed waveform with a
measurement device to check that no vibration occurs. If the vibration occurs due to high gain, the vibration may cause
early damage to the rotary servo motor.
• Use the product within the specified environment. For the environment, refer to the specifications of the rotary servo motor
series.
• To prevent an encoder malfunction from occurring, do not apply shocks, e.g. hit with a hammer, when coupling the shaft
end of the rotary servo motor.
• To prevent the shaft from being broken, do not subject the shaft of the rotary servo motor to more than the permissible load.
• To prevent the shaft from being broken and bearing from being worn out, do not use a rigid coupling when coupling a load
to the rotary servo motor.
• To prevent vibration during rotary servo motor operation and to prevent damage to the bearings and encoder, the balance
level of the load needs to be as even as possible.
• To prevent a malfunction, do not use the rotary servo motor where the shaft-through portion may be subject to pressure
(e.g. compressed air).
• Take safety measures such as providing covers to avoid accidentally touching the rotor of rotary servo motor during
operation.
• Do not get on the equipment or put a heavy load on it.
• Do not drop or strike the rotary servo motor.
• To prevent a fire or injury from occurring in case of an earthquake or other natural disasters, securely install, mount, and
wire the rotary servo motor in accordance with the user's manual.
• To prevent an electric shock or a fire, do not disassemble, repair, or modify the product. Disassembled, repaired, and/or
modified products are not covered under warranty.
• The equipment must be installed in the specified direction.
• Do not use the product in environments where it is exposed to strong magnetic fields, electric fields, or radiation. Doing so
may cause operation failure or malfunction.
