Receiving and Maintenance Information

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 (-25° to 158° F)

• within the relative humidity range, 5% to 95% non-condensing

• in a non-corrosive atmosphere

H-Series Motor Installation Instructions 3

ATTENTION

!

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.

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.

Using Shaft Seals

An additional seal is required on the motor shaft near the motor front
bearing, if the shaft is exposed to fluids or significant amounts of fine
dust. This includes lubricating oil from a gearbox. The motor ingress
protection (IP) rating depends on the usage of shaft seals and
environmentally sealed connectors/cables. The additional seal is not
recommended in applications where the motor shaft area is free of liquids
or fine dust. Refer to Shaft Seal Kits on page 17 to find the catalog number
of the seal kit for your H-Series motor.

4 H-Series Motor Installation Instructions

ATTENTION

!

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 14 for guidelines on how to achieve 20,000 hours of motor bearing
life.

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.
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, couplings, or pulleys with
tools during installation or removal. Use a wheel
puller applying pressure from the user end of the
shaft to remove any friction fit or stuck device from
the motor shaft.

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

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.

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 possible.

2. Route signal cables (encoder, serial, analog) away from motor and

power wiring.

3. Separate cables by a minimum of 0.3 m (1 ft) 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 equipment damage.

H-Series motors with high resolution encoders
require the use of Allen-Bradley power and
feedback cables.

H-Series connector kits do not provide the
necessary connector grounding for use with high
resolution encoders.

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