2INSTALLATION
Precautions
• The cables should not be damaged, stressed, loaded, or pinched.
• Install the direct drive motor on incombustible material. Installing them directly or close to combustibles will lead to smoke
or a fire.
• Provide an adequate protection to prevent screws and other conductive matter, oil and other combustible matter from
entering the direct drive motor.
• Direct drive motor may be hot depending on the operating method. Take safety measures such as providing covers.
• Stacking in excess of the specified number of product packages is not allowed.
• Do not hold the cables, connectors, rotor, or encoder when carrying the direct drive motor. Otherwise, it may drop.
• Install the direct drive motor in a load-bearing place in accordance with the user’s manual.
• The equipment must be installed in the specified direction.
• Use the product within the specified environment. For the environment, refer to the specifications of the direct drive motor.
• Securely fix the direct drive motor to the machine. If attached insecurely, the motor may come off during operation.
• Do not install or operate a direct drive motor, which has been damaged or has any parts missing.
• To prevent a malfunction on the encoder, do not apply shocks, e.g. hit with a hammer, when coupling the rotor of the direct
drive motor.
• To prevent the rotor from being damaged, do not subject the rotor of the direct drive motor to more than the permissible
load.
• To prevent a connection failure, malfunction, or others, do not strike the connector.
• Be sure to measure the vibration level with the direct drive motor mounted on the machine. A great vibration may cause
early damage to a bearing and encoder. The great vibration may also cause the poor connector connection or screw
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
early damage to the direct drive motor.
• To illustrate details, the equipment in the diagrams of this manual may have been drawn without covers and safety guards.
When the equipment is operated, the covers and safety guards must be installed as specified. Operation must be
performed in accordance with this user’s manual.
• To prevent the vibration during direct drive motor operation, or the cause of the damage to the bearings and encoder, the
balance level of the load needs to be as even as possible. To prevent malfunction, do not use the direct drive motor where
the shaft-through portion may be subject to pressure (e.g. compressed air).
• Take safety measures such as providing covers to avoid accidentally touching the rotor of direct drive motor during
operation.
• Do not get on or put heavy load on the equipment.
• Do not drop or strike the direct drive motor.
• To prevent a fire or injury from occurring in case of an earthquake or other natural disasters, securely install, mount, and
wire the linear servo motor in accordance with the user’s manual.
• To prevent an electric shock or a fire, do not disassemble, repair, or modify the product. Disassembled, repaired, and/or
modified products are not covered under warranty.
• 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.

Z-phase mark
The following shows the configuration of a direct drive motor. When using the direct drive motor, note the following.
Minimum oscillation angle
For a direct drive motor that performs a rotating oscillating motion within 70 °, rotate the motor more than 90 ° at least once a
day to keep the bearings lubricated.
Z-phase position
Z-phase pulse is on (Z-phase mark passing) when the Z-phase mark on the rotor end of the direct drive motor is in the
connector area. Keep the Z-phase position visible even after the direct drive motor is installed to a machine.
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 or more, install the direct drive motor in a position where the Z-phase mark
can pass over the connector area.
In order to turn the Z-phase pulse, Z phase mark needs to be rotated ±15° or more with respect to the center of the connector
mounting part.
For 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 poles detection is not
required.

2.4Permissible load for the rotor
Do not use rigid coupling, as it may damage the rotor.
For the permissible rotor load specific to the direct drive motor, refer to the following.
Page 39 Specification list
• When coupling a load to the direct drive motor, the load applied to the rotor must be within the permissible load.
• The load, which exceeds the permissible load, can cause the bearing life to reduce and the rotor to break.
• 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.
