2090-Series Motor/Actuator Cables
Before You Begin Remove all packing material from within and around the item. After unpacking,
verify the catalog number against the purchase order and visually inspect the
cable and each connector for damage. If necessary, notify the carrier of any
shipping damage immediately.
Cables are stored and shipped in a coil. Cables retain this shape until you
straighten the cable. To straighten a cable, hang a short cable from its mid-point
or lay a long cable on the floor in a straight line. Any coiling that remains in the
cable is straightened out within the next 24 hours and a straight cable is easier to
install.
Observe the following precautions when installing the cables in a servo system.
Failure to observe these safety notices can result in personal injury or damage to
the motor and equipment.
ATTENTION: If the power/brake or feedback cables are connected or
disconnected, while power is applied to the drive, arcing or unexpected motion
can occur.
Always remove power to the servo drive before connecting or disconnecting cables
at the drive or at the motor.
ATTENTION: To avoid electrical shock, make sure shielded power cables are
grounded at a minimum of one point. To help protect against the build-up of
electrical energy, factory-supplied power cables use one of these grounding
techniques:
•
The overall shield is bonded to the connector housing.
•
A section of the overall shield is exposed for connection to ground.
•
The overall shield is connected to a ground wire.
If the exposed cable braid or a ground wire is present, connect it to the power cable
clamp, housing, or another suitable chassis ground on the drive.
ATTENTION: The maximum cable length between the drive and motor varies,
depending on the drive/motor combination, but never exceeds 90 m (295.5 ft).
See Kinetix® Servo Drives Specifications, publication
GMC-TD003 , for more
information.
ATTENTION: Do not tightly gather or coil the excess length of a power cable.
Heat is generated within a cable whenever power is applied. Always position a
power cable so it can freely dissipate heat.
Do not coil a power cable except for temporary use when building or testing a
machine. If you temporarily coil a power cable, you must also derate the cable to
meet local code or follow an authoritative directive, such as Engineering Section
310.15(C) of the NEC Handbook.
