The customer is responsible for inspecting the equipment before
accepting the shipment from the freight company. Check the item(s) you
receive against your purchase order.
Maintain your motor within the following environmental conditions:
• in a clean, dry location
• within the operating temperature range, 0° to 40° C (32° to 104° F)
• within the storage temperature range, -30° to 70° C (-22° to 158° F)
• within the relative humidity range, 5% to 95% non-condensing
• in an non-corrosive atmosphere

ATTENTION
!
Before You Install 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.
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 the equipment being damaged.
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.

4 LD-Series Motor Installation Instructions
Preventing Electrical Noise
ElectroMagnetic Interference (EMI), commonly called noise, may
adversely impact motor performance by inducing stray signals. Effective
techniques to counter EMI include filtering the AC power, shielding and
separating signal carrying lines, and practicing good grounding
techniques.
Effective AC power filtering can be achieved by using isolated AC power
transformers or properly installed AC line filters.
To help avoid EMI:
1. Physically separate signal lines from motor cabling and power wiring.
Do not route signal wires with motor and power wires, or over the vent
openings of servo drives.
2. Ground all equipment using a single-point parallel ground system that
employs ground bus bars or large straps. If necessary, use additional
electrical noise reduction techniques to reduce EMI in noisy
environments.

ATTENTION
!
Building and Installing Cables
Knowledgeable cable routing and careful cable construction improves
system ElectroMagnetic Compatibility (EMC).
To build and install cables, perform the following steps:
1. Keep wire lengths as short as physically possible.
2. Route signal cables (encoder, serial, analog) away from motor and
power wiring.
3. Separate cables by 0.3 m (1 ft) minimum for every 9 m (30 ft) of parallel
run.
4. Ground both ends of the encoder cable shield and twist the signal wire
pairs to prevent electromagnetic interference (EMI) from other
equipment.
High voltage can be present on the shield of a
power cable, if the shield is not grounded.
Ensure there is a connection to ground for any
power cable shield.
Failure to observe these safety procedures could
result in personal injury or damage to equipment.

ATTENTION
!
Installing Your Motor
All motors include a mounting pilot for aligning the motor on a machine.
Preferred fasteners are stainless steel. The installation must comply with
all local regulations and use of equipment and installation practices that
promote electromagnetic compatibility (EMC) and safety.
Unmounted motors, disconnected mechanical
couplings, and/or disconnected cables are
dangerous if power is applied.
Disassembled equipment should be appropriately
identified (tagged-out) and access to electrical
power restricted (locked-out).
Failure to observe these safety procedures could
result in personal injury

ATTENTION

Guidelines for Installation
Observe the following for installing the motor.
1. Allow sufficient clearances in the area of the motor for it to stay within
its specified operating temperature range. Refer to Receiving and
Maintenance Information on page 2 for operating range. Do not
enclose the motor unless forced air is blown across the motor for
cooling. A fan blowing air across the motor will improve its
performance. Keep other heat producing devices away from the motor.
2. Refer to Mounting Dimensions on page 8 to determine the mounting
dimensions of your motor.
3. Place the motor with connectors pointing downward.
4. Properly mount and align the motor.
5. Attach all power and encoder cables after the motor is mounted and
use a drip loop in the cable to keep liquids flowing away from the
connectors.
Outer surfaces of motor can reach high
temperatures, 100° C (212° F) during motor
operation.
Take precautions to prevent accidental contact with
hot surfaces. Consider motor surface temperature
when selecting motor mating connections and
cables.
Failure to observe these safety procedures could
result in personal injury or damage to equipment.
