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.
WARNING
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
The maximum length of cabling between the drive and the motor must not exceed 90 m
(295.5 ft). Also, a maximum of two (2) extension cables may be connected from a motor to
a drive.
WARNING
To avoid the hazard of electrical shock, ensure 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
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.
