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.

2.1 Equipment configuration
The following shows the configuration of a direct drive motor. When using the direct drive motor, note the
following.
(1) Minimum oscillation angle
If the direct drive motor rotates repeatedly by a small angle (by 70or less), make the direct drive motor
rotate by 90or more at least once a day in order to keep the bearing lubricated.
(2) Z-phase position
A Z-phase pulse turns on (Z-phase mark passing) when the Z-phase mark on the rotor end of the direct
drive motor passes over the connector area. Keep the Z-phase position visible even after the direct drive
motor is installed to a machine.
Rotor (output shaft)
Encoder connector
Power supply connector
A Z-phase pulse turns
on when the Z-phase
mark passes over
the connector area.
Z-phase mark
(3) Precautions for Z-phase mark passing
After power on, the Z-phase mark of the direct drive motor must pass the connector area once. In a
system which prevents the direct drive motor from making a full rotation, install the direct drive motor in a
position where the Z-phase mark can pass over the connector area.
(4) Vertical axis (lift)
For the system where the unbalanced torque occurs, such as a vertical axis system (lift), use the direct
drive motor in the absolute position detection system. In the absolute position detection system, the
absolute position is established when the Z-phase mark passes the connector area once. Therefore, at
system startup, make the Z-phase mark pass over the connector area, and switch the servo amplifier's
power supply from off to on.
If the direct drive motor can be rotated manually, make the Z-phase mark pass over the connector area
while only the servo amplifier's control circuit power supply is on. After that, switch the servo amplifier's
power supply from off to on.
If the direct drive motor cannot be rotated manually, detect the magnetic poles while the torque is
balanced, then run the direct drive motor in the test mode to make its Z-phase mark pass over the
connector area. After that, switch the servo amplifier's power supply from off to on. After the Z-phase
mark passes over the connector area once, magnetic pole detection is not required.

POINT
During assembling, the rotor must not be hammered. Otherwise, the encoder
may malfunction.
(1) The direction of the encoder on the direct drive motor cannot be changed.
(2) When mounting the direct drive motor, use spring washers, etc. and fully tighten the bolts so that they do
not become loose due to vibration.
2.4 Permissible load for the rotor
CAUTION Because the rigid coupling may damage the rotor, make sure to align and center
the load on the rotor.
For the permissible rotor load specific to the direct drive motor, refer to section 7.3.
(1) When coupling a load to the direct drive motor, the load applied to the rotor must be within the
permissible load.
(2) The load, which exceeds the permissible load, can cause the bearing life to reduce and the rotor to
break.
(3) The load indicated in this section is static load in a single direction and does not include eccentric load.
Make eccentric load as small as possible. Not doing so can cause the direct drive motor to be damaged.
