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, and will retain this shape unless you allow
the cable to straighten itself. 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
persists in the cable should relax within the next twenty-four hours. Doing this
results in a cable that is easier to install.
Observe the following precautions when installing the cables in a servo system.
Failure to observe these safety notices could result in personal injury or damage to
the motor and equipment.
ATTENTION: Arcing or unexpected motion can occur if the power, brake,
or feedback cables are connected or disconnected while power is applied
to the drive. Always remove power to the servo drive before connecting or
disconnecting cables at the drive or at the motor.
ATTENTION: To avoid the hazard of electrical shock, make sure shielded
power cables are grounded at a minimum of one point. To prevent 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 length of cabling between the drive and the
motor must not exceed 90 m (295.5 ft), and a maximum of two extension
cables may be connected between a drive and a motor. Refer to the
Kinetix Motion Control Selection Guide, publication
additional 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 may freely dissipate any heat.
A power cable should not be coiled, 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 a authoritative directive, such
as Engineering Section 310.15(C) of the NEC Handbook.
