2. DIRECT DRIVE MOTOR
2 - 2
2.3 Installation
WARNING
To prevent electric shock, ground each equipment securely.
CAUTION
Stacking in excess of the limited number of product packages is not allowed.
Install the equipment on incombustible material. Installing it directly or close to
combustibles will lead to a fire.
Install the equipment in a load-bearing place in accordance with this Instruction
Manual.
Do not get on or put heavy load on the equipment to prevent injury.
Use the equipment within the specified environmental condition range.
Refer to the specifications of the direct drive motor series.
Do not subject the direct drive motor to drop impact or shock loads as they are
precision equipment.
Do not install or operate the direct drive motor which has been damaged or has any
parts missing.
Do not carry the direct drive motor by holding the cables, rotor, encoder or
connector. Otherwise, a fault or injury may occur.
Securely fix the direct drive motor to the machine. If fixed insecurely, the direct drive
motor will come off during operation, leading to injury.
Measure a direct drive motor, and check the motor vibration level. A great vibration
may cause the early damage of 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 by using 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 direct drive motor.
When coupling the rotor end of the direct drive motor, do not subject the rotor end to
impact, such as hammering. The encoder may become faulty.
When coupling a load to the direct drive motor, make sure to align and center the
load on the motor flange rabbet. Particularly, when the rigid coupling is used, the
slight center deviation may cause the decline of the position accuracy, and may
cause the rotor damage.
Balance the load to the extent possible. Failure to do 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 direct drive motor rotor 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.
When treating the direct drive motor, be careful about the edged parts such as the
corners of the direct drive motor.
