2. INSTALLATION
WARNING
To prevent electric shock, ground each equipment securely.
CAUTION
Stacking in excess of the specified number of product packages is not allowed.
Install the direct drive motor on incombustible material. Installing them directly or
close to combustibles will lead to smoke or a fire.
Install the servo amplifier and the direct drive 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 environment. For the environment, refer to
section 7.3.
Do not drop or strike the direct drive motor as it is precision equipment.
Do not install or operate a direct drive motor, which has been damaged or has
any parts missing.
Do not hold the cables, rotor, encoder, or connector when carrying the direct drive
motor. Otherwise, it may drop.
Securely fix the direct drive motor to the machine. If being attached insecurely,
the motor may come off during operation, leading to injury.
Do not apply shocks, e.g. hit with a hammer, when coupling the rotor of the direct
drive motor. Otherwise, the encoder may malfunction.
When coupling a load to the direct drive motor, make sure to align and center the
load on the motor flange rabbet. Particularly, when a rigid coupling is used, even
a slight center deviation may reduce position accuracy or damage the rotor.
Balance the load to the extent possible. Not doing so can cause vibration during
direct drive motor operation or damage the bearings and encoder.
Take safety measures, e.g. provide covers, to prevent accidental access to the
rotor of the direct drive motor during operation.
Do not subject the rotor of the direct drive motor to more than the permissible
load. Otherwise, the rotor may break, leading to injury.
When the product has been stored for an extended period of time, contact your
local sales office.
Be sure to check the vibration level with the direct drive motor mounted on the
machine. A great vibration may cause the early damage of a bearing and
encoder. 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 direct drive motor.
Do not use the direct drive motor where the shaft-through portion may be subject
to pressure (e.g. compressed air). Applying air pressure to the inside of the direct
drive motor may cause a malfunction.
