Magnetic field
NOTICE
To avoid magnetic interference to the absolute encoder, do not use
electromagnetic devices near the absolute encoder, such as
electromagnetic memory sticks, memory cards, and key cards.
Keep the servo motor with an absolute
encoder at least 15 mm away from the
devices that produce a magnetic field
stronger than 10 mT.

Lifting a motor (for high inertia motor only)
WARNING
Death or injuries by unresolved burdens
At the transport the motor can cause death or injuries by unchecked
movements.
• Use lifting equipment and load suspension devices which are only
interpreted for the burden of the motor and intact.
• Do not stay under and in the jib range of unresolved burdens.
• Safeguard the motor against rolling away at the side when
removing.
• Do not lift a motor by pulling the cables.
NOTICE
Do not overtighten the eyebolts of 1FL609❑ motors.
• For 1FL609❑ motors, the eyebolts must
• Lift 1FL609❑ motors at the eyebolts.
Installing a key (optional)
WARNING
Injuries by an ejected key
When a motor using a key is running, the fitted key on the shaft may
be ejected, which can cause personal injuries. The fitted key on the
shaft must be firmly secured to prevent them from being flung out.
NOTICE
For the motor using a key (②), the key is
preinstalled on the shaft extension. When
reinstalling it, do not strike the key slot
(①).
Mounting a motor
WARNING
Personal injuries and material damages by the drop of a vertical
axis
When a servo motor with a brake is used as a vertical axis, the axis
will drop if the positive and negative poles of the 24 V DC power
supply for the servo drive are connected inversely. Unexpected drop
may cause personal injuries and material damages.

of an unexpected drop. In addition, make sure that the 24 V DC power
2 supply is correctly connected.
2 NOTE
To ensure better heat dissipation, do not insert any insulators between
the motor flange and the mounting flange.
Mount the motor through a mounting steel flange, as shown in the left
figure.
NOTICE
When a motor is used with a flange coupling, ensure that the radial
deviation is smaller than 0.03 mm. Otherwise, the bearing will be
damaged.
NOTE
The required alignment accuracy differs with the motor speed and the
coupling type. Please determine the accuracy according to actual
applications.
If the coupling gives out abnormal sounds, refer to the step "Aligning
a coupling" to realign the coupling until the sounds disappear.
NOTICE
The belt tension must be smaller than the allowable radial forces of the
motor.

Selecting a coupling
Use a flexible coupling with high torsional
rigidity specifically designed for servo
motors, which allow to transfer the motor
torque to the mechanics and to
compensate radial, axial and angular
misalignments.
Installing a coupling
NOTICE
Do not strike the shaft when installing a
coupling and ensure that the radial and
axial forces are smaller than the allowable
maximum values specified in the
Operating Instructions.
Aligning a coupling
• Turn the motor shaft and the machine
shaft to align the coupling.
• An alignment accuracy test is preferred.
If unachievable, judge the accuracy by
observing whether the coupling can
slide smoothly on both shafts.
Coupling realignment
Tension measurement
• Measure the belt tension at multiple
points using a tension meter while
turning the motor shaft by 45° .
• Try your best to reduce the axial
misalignment of the belt-pulleys to keep
the axial forces to the motor shaft to a
minimum
