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

equipment.

Installation and Maintenance Guidelines

This section advises you on how to install your product so it provides safe and reliable service.

T o 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

Motor is position ed so ca ble
enters from above, and
cable lacks 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.

Cable enter s beneath the motor,
and drip loop is formed.

• If design requirements permit, provide shields that protect the motor housing, shaft, seals and
their junctions from product conta mination, caustic agent s, and high pressure fluids.

• Replace the optional shaft seal at or before its expected twelve-month lifetime elapses.
Refer to Remove and Install a Shaft Key on page 21 for more information on sha ft seals.

• Inspect the motor and seals for damage or wear on a regular basis. If damage or adverse wear
is suspected, replace the item.

• If desired, the motor front flang e may be sealed to the driven equipment by a bead of RTV
around the periphery of the motor to equipment joint. Use of a gasket or RTV on the mating
surfaces may cause misalignment of the shaft and result in damage to the motor and driven
equipment.

• Brakes on these servo motors are holding brakes. The brakes are spring-set, and release when
voltage is applied to the brake coil. A power source, either external or internal to the servo
drive, is required to disengage the brake. The power source may be applied by the machine
controller.

If system main power fails, holding brakes can withstand occasion al use as stopping brakes.
However, this 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 are designed to hold a motor
shaft at 0 rpm for up to the rated brake holding torque.

Follow these steps to prevent shaft rotat ion.

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 pot ent ial for brake wear caused by a badly

tuned servo system oscillating the shaf t .

Mechanical Connections

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 machine and the
motor shaft must be rigid to achieve acceptable system response. Periodically inspect connections to
verify their rigidity.

When mounting couplings or pulleys to the shaft, verify 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 17 for guidelines on how to achieve 20,000 hours of
motor bearing life.

ATTENTION

Do not strike the shaft, key, couplings, or pulleys with tools dur ing installation or
removal.

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 also may result by applying leverage from the faceplate to remove
devices mounted on the motor shaft.

Apply a constant pressure, with a wheel puller for example, to the user end of the shaft
to remove a friction fit or a stuck device.

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

A shaft key provides a rigid mechanical connection with the pot ential for self-alignment, but the key
must be properly installed in the keyway. Refer to these sections for additional information:

• Dimensions on page 12 for dimensional information about the key and shaft keyway.

• Remove and Install a Shaft Key on page 21 for recommendations on how to remove and

install a shaft key.

Interconnect Cables

Knowledgeable cable routing improves system electromagnetic compatibility (EMC). Refer to
Shielding of Brake Wires Within the Power Cable on page 9 for cable shield grounding at the servo
drive.

Follow these steps to install the cables.

1. Keep wire lengths as short as physically possible.

2. Route signal cables away from motor and power wiring. Typical signal cables transmit

encoder, serial, or analo g data at low vo lt ages.

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.

Verify there is a connection to ground for all shields in the power cable.
Failure to observe these safety procedures could result in per s onal injury or

damage to equipment.

Electrical Noise

ElectroMagnetic Interference (EMI), commonly called noise, adversely impacts 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 prop erly installed ac line
filters.

To reduce EMI follow these guidelines:

• Physically separate signal lines from mo t or cabling and power wiring. Do not route signal
wires with motor and power wires, and do not route signal wires over the vent openings of
servo drives or other electrical power sources.

• Ground all equipment by 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.

Shaft Seals

You may install the optional shaft seal to protect the front bearing from fluids or fine dust that could
contaminate the motor bearing and reduce its lifetime. The IP rating for the motor depends on the
usage of shaft seal s.

Refer to these sections for additional information:

• Shaft Seal Kits on page 23 lists catalog numbers of seal kits available for your motor.

• Specifications on page 22 briefly describes IP ratings.

Install the TL-Series Motor

Before installing the motor, review and become familiar with the following instructions:

• Requirements for Motor Mounting

• Power Cable Shielding

• Installing the Motor

• Dimensions

• Motor Load Force Ratings

• Connector Data

Requirements for Motor Mounting

All TL-Series 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 and safety.

ATTENTION

Unmounted motors, disconnected mechanical couplings, loose shaft keys, and
disconnected cables are dangerous if power is applied.

Disassembled equipment should be app ropriately identified (t agged-out) and
have access to electrical power restricted (locked-out).

Before applying power to the motor, remove the shaft key and other mechanical
couplings that could be thrown from the shaft.

Failure to observe these safety procedures could result in per s onal injury.
