Before You Begin
Before unpacking the product, inspect the shipping carton for damage. If damage is visible,
immediately contact the shipper and request assistance. Otherwise, proceed with unpacking.
Remove the motor carefully from its shipping container, and visually inspect the motor for any
damage. Carefully examine the motor frame, front output shaft, and mounting pilot for any defects.
Keep the original packing material in case you need to return the product for repair or transport it to
another location. Use both the inner and outer packing cartons to verify adequate protection for a
unit returned for service.
Installation and Maintenance Guidelines
This section advises you on how to install your product so it provides safe and reliable service.
To Prolong Motor Life
Thoughtful design and proper maintenance can increase the life of a servo motor.
• Always install the motor with the cable entry point(s) positioned underneath the motor
housing, and provide a drip loop in each cable. A drip loop is a downward bend in the cable
that lets water gather and drip off the cable rather than continue to flow along the cable.
These two installation practices greatly reduce the potential for moisture related problems.
Recommended Connector Orientation with Drip Loop
• Avoid installing the motor with the shaft pointing upward. This orientation increases the risk
of contaminant ingress.
• Avoid spraying liquids under pressure directly on the junction of the motor shaft, housing,
and connectors, as well as the enclosure joints. Fluids under pressure can be forced around
worn seals, and contaminate the motor bearings. Bearing contamination will significantly
shorten the life of a servo motor.
ATTENTION
Do not attempt to open and modify the motor. Modifications that can be performed in
the field are described in this manual, other changes should not be attempted.
Only a qualified Allen-Bradley employee can service this type of motor.
Failure to observe these safety procedures could result in personal injury or damage to
equipment.
Cable enters beneath the motor,
and drip loop is formed. Motor is positioned so cable
enters from above, and
cable lacks drip loop.
