WARNING
Death or injuries by unresolved burdens
At the transport the motor can cause death or injuries by unchecked
movements.
• Use lifting equipments 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 motors.
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.
Mounting a motor
NOTE
To ensure better heat dissipation, do not insert any insulators between
the motor flange and the mounting flange.

Lifting a motor
• Screw in the eyebolts manually
and completely before lifting the
motors.
• Lift the motors only at the eyebolts.
• When mounting the motors
vertically, screw the eyebolts in the
screw holes on the two side walls
of the non-drive end shield.
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).
Mount the motor through a mounting
steel flange. Use four M12 screws with
a tightening torque of 84 Nm.
Remove the anchor plates with a
wrench, tighten the screws to fix the
motor to the mounting plate, and then
reinstall the anchor plates. Use the
screws properly as required below:

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.
NOTICE
When a motor is equipped 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.

WARNING
Personal injuries by
If you connect the cables with the power supply switched on, it may
cause personal injuries by a hazardous voltage and unregulated move
from the motor.
• Switch off the power supply.
• Make sure that there are no voltage conditions.
• Prevent the energy sources from switching on again.

NOTICE
Do not put much stress upon cables or connectors while wiring.
NOTE
• The recommended sequence for cable connections is as follows:
encoder cable first, power cable next, and then the fan cable.
• There are threaded holes available on both sides of the terminal box
housing for you to pass the cables through. You can select to
connect the individual cables to the terminal boxes from the
threaded holes on the desired side.
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
.
hazardous voltage and unregulated move
Before connecting
Before connecting the cables, you must take
necessary ESD protection measures, e.g.
wearing an ESD wrist strap, ESD gloves,
and ESD clothes.
