Cable Shielding
The single motor cable contains power and digital encoder signals. It must be shielded, and the
cable shield must connect to ground.
Knowledgeable cable routing improves system electromagnetic compatibility (EMC). To install
the single motor cable, follow these steps.
1. Keep the cable length as short as possible.
2. Ground both ends of the cable shield and twist the signal wire pairs to prevent
electromagnetic interference from other equipment.
Mount and Connect the Motor
To install a Bulletin VPS motor, follow these procedures and recommendations.
SHOCK HAZARD: High voltage can be present on the shields of the single motor cable if the
shields are not grounded.
Verify that there is a connection to ground for all shields in the single motor cable.
Failure to observe these safety procedures could result in personal injury or damage to equipment.
ATTENTION: The overall shield on the motor cable must be grounded to obtain an effective
encoder signal.
The encoder data signal is transmitted through an impedance-matched twisted-wire pair that
requires effective shielding for optimum performance.
Be sure there is an effective connection between the motor cable shield and the drive system
ground.
ATTENTION: Servo motors are not for direct connection to an AC power line.
Servo motors are designed for connection to a servo drive that controls the application of AC
power.
Failure to observe these safety precautions could result in damage to the motor and equipment.
ATTENTION: Do not strike the shaft, couplings, or pulleys with tools during installation or removal.
Damage can occur to the motor bearings and the feedback device if you apply a sharp impact to
the shaft during installation of couplings and pulleys, or a shaft key.
Failure to observe these safety procedures could result in damage to the motor and its
components.
