2. Refer to Motor Load Force Ratings on page 11 to determine the radial and axial
shaft load limitations of your motor.
3. Position the motor with the cable mounts pointing downward.
4. Properly mount and align the motor.
5. Connect the feedback, power, and brake cables after the motor is mounted.
Motor Load Force Ratings
Motors are capable of operating with a sustained shaft load. The radial and axial
load force location is shown in the figure, and maximum values are in the tables.
Note: Loads are measured in pounds, kilograms are mathematical conversions.

Load Forces on Shaft
The following tables represent 20,000 hour L10 bearing fatigue life at various loads
and speeds. The 20,000 hour life does not account for application-specific life
reduction that may occur due to bearing grease contamination from external sources.

ATTENTION
Mount the motor so exposure to dust and liquids is minimized
for both the motor and its cable connections, and restrain cables
to prevent uneven tension or flexing at the connectors.
Short circuits in the feedback, power, or brake circuits may
result from exposure of the unsealed motor cable connectors to
dust or liquids, or by uneven forces at the connector housing.
Failure to observe these safety procedures could result in
personal injury or damage to the motor and equipment.
