About Continuous-flex Power and Power with Brake Cables
Continuous-flex motor power cables, with or without brake connections, can be repeatedly
flexed within a specified bend radius when properly installed. The cables have circular SpeedTec
connectors at the motor end, and flying leads at the drive end.

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: 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:
• Bond the overall shield to the connector housing.
• Connect an exposed section of the overall shield to ground.
• Connect an exposed cable braid or a ground wire, if present, to the power cable
clamp, housing, or another suitable chassis ground on the drive.
Failure to observe these safety procedures could result in personal injury or
equipment damage.

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.
Install Cables
Follow these steps when installing a cable.
1. Provide the recommended installation areas, and the correct offset from features, before
beginning any cable bend.
Features include these areas on the cable:
• Connectors
• Transitions from exposed wire to insulation (for example, flying leads)
• Exposed cable ground shields
The offset from these areas should be greater than or equal to (>1x) the cable diameter.
2. Keep cable bends within the bend radius listed in the Specifications
General guidelines for the bend radius of a cable are listed below, however, individual
cables may have additional restrictions:
on page 7.
• Standard cables have a static or one-time bend radius of 10 times (<10x) the cable
diameter.
• Continuous-flex cables have an operational bend radius of 12 times (<12x) the cable
diameter.

If an O-ring is installed, a SpeedTec plug will not engage with the receptacle.
3. Observe these restrictions on the flex zone and installation areas when installing the
cable:
• The flex zone is the area in which the cable can repeatedly flex up to its specified
bend radius.
• Installation areas require rigid mounting to prevent the cable from flexing where it
connects to other components.

4. Identify each connection on a cable by attaching a label around the outer insulation of
each wire adjacent to the drive connection.
5. Remove the O-ring on the motor receptacle when using a cable with a SpeedTec plug.
The type of plug on the cable determines whether an O-ring is required on the
receptacle.
The O-ring dampens the effects of vibration at the cable-to-motor connection.
This creates a more secure connection for a cable with a threaded plug.
