A - 4
CAUTION
Do not apply shocks, e.g. hit with a hammer, when coupling the rotor of the direct drive motor. Otherwise,
the encoder may malfunction.
Do not subject the rotor of the direct drive motor to more than the permissible load. Otherwise, the rotor
may break.
When the product has been stored for an extended period of time, contact your local sales office.
When handling the direct drive motor, be careful about the edged parts such as corners of the direct
drive motor.
Do not strike the connector. Otherwise, it may cause a connection failure, malfunction, etc.
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.
To prevent a fire or injury in case of an earthquake or other natural disasters, securely install, mount, and
wire the servo motor in accordance with the Instruction Manual.
(2) Wiring
CAUTION
Wire the equipment correctly and securely. Otherwise, the direct drive motor may operate unexpectedly.
Make sure to connect the cables and connectors by using the fixing screws and the locking mechanism.
Otherwise, the cables and connectors may be disconnected during operation.
Do not install a power capacitor, surge killer, or radio noise filter (FR-BIF option) on the power wire of the
direct drive motor.
To avoid a malfunction, connect the power phases (U/V/W) of the servo amplifier and the direct drive
motor correctly.
Connect the servo amplifier power output (U/V/W) to the direct drive motor power input (U/V/W) directly.
Do not let a magnetic contactor, etc. intervene. Otherwise, it may cause a malfunction.

Do not connect AC power supply directly to the direct drive motor. Otherwise, it may cause a
malfunction.
When the cable is not tightened enough to the terminal block, the cable or terminal block may generate
heat because of the poor contact. Be sure to tighten the cable with specified torque.
