About Flexible Power Cables

Continuous flexible 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 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.
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.
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.
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.
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.
