INSTALLATION
Precautions
• Install the rotary servo motor on incombustible material. Installing them directly or close to combustibles will lead to smoke
or a fire.
• Provide an adequate protection to prevent screws and other conductive matter, oil and other combustible matter 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.
• Do not overtighten the eyebolts of the rotary servo motor. To prevent damage to the tap, avoid tightening too hard.
• Stacking in excess of the specified number of product packages is not allowed.
• Do not hold the cables, connectors, shaft, or encoder when carrying the rotary servo motor. Otherwise, it may drop.
• Install the rotary servo motor in a load-bearing place in accordance with the user's manual.
• Do not install or operate the rotary servo motor which has been damaged or have any parts missing.
• 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 motor vibration level with the rotary servo motor mounted on a machine when checking the
vibration level. A great vibration may cause early damage to a bearing, encoder, and brake. The great vibration may also
cause the 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 conditions, refer to the specifications of the rotary
servo motor series.
• To prevent a malfunction on the encoder, do not apply shocks, e.g. hit with a hammer, when coupling the shaft end of the
rotary drive 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, or the cause of a 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 provide covers, to prevent accidental access to the rotor of the rotary servo motor during
operation.
• Do not get on or put heavy load on the equipment.
• 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 linear servo motor in accordance with the user's manual.
• Do not disassemble, repair, or modify the product.
• The equipment must be installed in the specified direction.
