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
24 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.
Failure to observe these safety procedures could result in personal injury or
damage to the motor and equipment.
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 extension cables may be
connected from a motor to a 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 an authoritative directive, such as Engineering
Section 310.15(C) of the NEC Handbook.
Failure to observe these safety procedures could result in personal injury or
equipment damage.
ATTENTION: The examples in this publication show the available connections,
some of which may not be appropriate for your specific installation. Refer to your
drive installation instructions or user manual for recommended wire trim lengths,
and wiring examples appropriate to your drive and motor application.
Do not connect unused wires. Unused wires may be trimmed and finished as
necessary to prevent accidental contact with other wires or wire shields, or with a
ground connection.
Failure to observe these safety procedures could result in personal injury or
damage to the motor and equipment.
IMPORTANT Continuous-flex cables with SpeedTec connectors are incompatible with some
MP-Series motors.
