Before You Install the Motor
Before installing or storing the motor:
1. Remove the motor carefully from its shipping container.
2. Visually inspect the motor for any damage.
3. Examine the motor frame, front output shaft, and mounting pilot for
any defects.
4. Notify the carrier of any shipping damage immediately.
Using Couplings and Pulleys
Mechanical connections to the motor shaft, such as couplings and pulleys,
require a torsionally rigid coupling or a reinforced timing belt. The high
dynamic performance of servo motors can cause couplings, pulleys or
belts to loosen or slip over time. A loose or slipping connection will cause
system instability and may damage the motor shaft. All connections
between the system and the servo motor shaft must be rigid to achieve
acceptable response from the system. Periodically inspect connections to
verify their rigidity.
When mounting couplings or pulleys to the motor shaft, ensure that the
connections are properly aligned and that axial and radial loads are within
the specifications of the motor. Refer to Motor Load Force Ratings on page 11 for
guidelines on how to achieve 20,000 hours of motor bearing life.
ATTENTION
!
Do not open or attempt to open the motor.
Only a qualified Allen-Bradley employee can
service this type of motor.
Failure to observe these safety procedures could
result in personal injury or equipment damage.
