2. INSTALLATION
WARNING
CAUTION
To prevent electric shock, ground each equipment securely.
Stacking in excess of the specified number of product packages is not allowed.
Install the servo motor on incombustible material. Installing them directly or close
to combustibles will lead to smoke or a fire.
Install the servo motor in a load-bearing place in accordance with the Instruction
Manual.
Do not get on or put heavy load on the equipment. Otherwise, it may cause injury.
Use the equipment within the specified environmental range. For the
environment, refer to the specifications of the servo motor series.
Do not drop or strike the servo motor. Isolate it from all impact loads.
Do not install or operate a faulty servo motor.
Do not hold the cables, connectors, shaft, or encoder when carrying the servo
motor. Otherwise, it may drop.
Use the eyebolts of the servo motor to only transport it. Do not use the eyebolts to
transport the servo motor when it is mounted on a machine.
The geared servo motor must be mounted in the specified direction. Otherwise, it
can leak oil, leading to a fire or malfunction.
Securely fix the servo motor to the machine. If being attached insecurely, the
servo motor may come off during operation, leading to injury.
Be sure to measure the motor vibration level with the servo motor mounted on the
machine when checking the vibration level. A great vibration may cause the early
damage of a bearing, encoder, brake, and reducer. 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 the early
damage of the servo motor.
Never hit the servo motor or shaft, especially when coupling the servo motor to
the machine. Otherwise, the encoder may malfunction.
When coupling a load to the servo motor, do not use a rigid coupling. Doing so
can cause the shaft to break and the bearing to wear out.
Balance the load to the extent possible. Not doing so can cause vibration during
servo motor operation or damage the bearings and encoder.
Take safety measures, e.g. provide covers, to prevent accidental access to the
rotor of the servo motor during operation.
Do not subject the servo motor shaft to more than the permissible load.
Otherwise, the shaft may break, leading to injury.
When the product has been stored for an extended period of time, contact your
local sales office.
When handling the servo motor, be careful with the sharp edges of the servo
motor, shaft keyway, or others.
Do not use the servo motor where the shaft-through portion may be subject to
pressure (e.g. compressed air). Applying air pressure to the inside of the servo
motor may cause a malfunction.
