4. Additional instructions
The following instructions should also be fully noted. Incorrect handling may cause a malfunction, injury,
electric shock, fire, etc.
(1) Transportation and installation
CAUTION
Transport the products correctly according to their mass.
Use the eyebolt of the servo motor for the transportation purpose only. Do not use the eyebolts to
transport the servo motor when it is mounted on a machine.
Do not overtighten the eyebolts of the servo motor. Tightening too hard may damage the tap.
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 servo motor. Otherwise, it may
drop.
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.
The equipment must be installed in the specified direction.
Do not install or operate the servo motor which have been damaged or have any parts missing.
Do not block intake and exhaust areas of the servo motor with a cooling fan. Otherwise, it may cause a
malfunction.
Do not drop or strike the servo motor. Otherwise, injury, malfunction, etc. may occur.
Securely fix the servo motor to the machine. If being attached insecurely, the servo motor may come off
during operation.
The geared servo motor must be installed in the specified direction to prevent oil leakage.
When handling the servo motor, be careful with the sharp edges of the servo motor, shaft keyway, or
others.
Do not strike the connector. Otherwise, a connection failure, malfunction, etc. may occur.
Be sure to measure the motor vibration level with the servo motor mounted to the machine when
checking the vibration level. A great vibration may cause the early damage of a bearing, encoder, brake,
and gear 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, and then check that no vibration occurs. If the vibration occurs due to high
gain, the vibration may cause the early damage of the servo motor.
Take safety measures, e.g. provide covers, to prevent accidental access to the rotor of the servo motor
during operation.
Never hit the servo motor or shaft, especially when coupling the servo motor to the machine. Otherwise,
the encoder may malfunction.
Do not subject the servo motor shaft to more than the permissible load. Otherwise, the shaft may break.
To prevent a fire or injury from occurring in case of an earthquake or other natural disasters, securely
install, mount, and wire the servo motor in accordance with the Instruction Manual.
