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.

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 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.
