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.

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, damage to equipment, and void warranty
coverage.

Motor Installation and Maintenance Guidelines

The following sections provide general installation and maintenance information.
The information should assist you to correctly install and to provide maintenance
that will prolong the lifetime of your TL servo motor.

ATTENTION

Ensure that cables are installed and restrained to prevent
uneven tension or flexing at the cable connectors.

Excessive and uneven force at the cable connectors may result
in damage to the connector housings and contacts as the cable
flexes.

Failure to observe these safety procedures could result in
damage to the motor and its components.

6 TL-Series Servo Motor Installation Instructions

Prolonging Motor Life

Thoughtful design and proper maintenance can increase the life of a servo motor.
The following are guidelines to maximize the life of a servo motor.

• Always provide a drip loop in each cable to carry liquids away from connections.

• If design requirements permit, provide shields that protect the motor housing,

shaft seals, and their junctions from product contamination and fluids.

• Inspect the motor and seals for damage or wear at 6-month intervals. Replace
damaged items.

A dry and dusty environment will cause a seal to wear more rapidly than a wet or
oily environment. However, fluids can be forced around worn seals more easily
than dry particles. Replace a shaft seal at or before its expected lifetime, as
bearing contamination significantly shortens the life of a servo motor.

• Brakes on these servo motors are holding brakes. The brakes are spring-set, and
release when voltage is applied to the brake coil. A separate power source is
required to disengage the brake. This power source may be applied by a servo
motor controller, in addition to manual operator control.

The recommended method of preventing shaft rotation is:

1. Command the servo drive to 0 rpm.

2. Verify the motor is at 0 rpm.

3. Engage the brake.

4. Disable the drive.

Disabling the drive removes the potential for brake wear caused by a poorly
tuned servo system oscillating the shaft.

If system main power fails, holding brakes can withstand occasional use as
stopping brakes. This situation allows some shaft rotation as the braking occurs,
and also may create mechanical backlash within the system. Braking with power
applied to the motor is potentially damaging to the system, increases brake wear,
and reduces brake life.

IMPORTANT

Holding brakes are not designed to stop rotation of the
motor shaft, nor are they intended to be used as a safety
device. They will hold a motor shaft at 0 rpm for up to the
rated brake holding torque.

Making Mechanical Connection to the Motor Shaft

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

A shaft key provides a rigid mechanical connection with the potential for
self-alignment, but the key must be properly installed in the keyway. Refer to:

• Mounting Dimensions on page 15 for dimensional information about the key and
shaft keyway, and

• Removing and Installing a Shaft Key on page 20 for recommendations on how to
remove and install a shaft key.

Damage may occur to the motor bearings and the feedback
device if sharp impact to the shaft is applied during installation
of couplings and pulleys, or a shaft key. Damage to the
feedback device may result by applying leverage from the
motor mounting face to remove devices mounted on the motor
shaft.

Do not strike the shaft, key, couplings, or pulleys with tools
during installation or removal. Apply a constant pressure (e.g.,
with a wheel puller) to the user end of the shaft to remove any
friction fit or stuck device from the motor shaft.

Failure to observe these safety procedures could result in
damage to the motor and its components.

Installing Cables

Knowledgeable cable routing improves system electromagnetic compatibility
(EMC). To install the cables:

1. Keep wire lengths as short as physically possible.

2. Route signal cables (encoder, serial, analog, etc.) 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 cable shield and twist the signal wire pairs to prevent

electromagnetic interference (EMI) from other equipment.

ATTENTION

High voltage can be present on the shields of a power cable, if
the shields are not grounded.

Ensure there is a connection to ground for all shields in the
power cable.

Failure to observe these safety procedures could result in
personal injury or damage to equipment.

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:

• 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.
