About Continuous-flex Feedback Cables

Continuous-flex feedback cables can be repeatedly flexed within a specified bend radius when
properly installed. A circular SpeedTec-ready receptacle and/or a SpeedTec plug is attached to
the cable.

Continuous-flex Feedback Cables with SpeedTec DIN Connector 3

IMPORTANT

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 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.

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.

Continuous-flex cables with SpeedTec connectors are incompatible with some
MP-Series motors.

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 (>

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:

• 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.

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 flex many times without breakage.

• Installation areas require rigid mounting to prevent the cable from flexing where it

connects to other components.

1x) the cable diameter.
