A-B 1326 Cables for 460V AC Servo Motors

Servomotor Cable

Series B Power cables (catalog number 1326-CPB1 and 1326-CPC1)

and commutation cables (catalog number 1326-CCU and 1326-

CECU) are available in lengths up to 90 m (295 ft) for standard, one

time flex applications. (PLTC 90° C 300V, AWM 90° C 300V for

1326-CCU and 1326-CECU, type TC 90° C 600V for 1326-CPB1

and 1326-CPC1.) Each cable features:

• UL Listed (file #E88699) cable assemblies.

• A braided cable shield for superior electromagnetic noise immunity.

• Molded push/pull connectors at the motor end for easy installation and maintenance.

Cable systems for 1394 Motion Control System:

• Standard single-connector cables.

• Right-angle connector cables.

• In-line system that uses bulkhead and double-ended cables.

• Harsh environment cables.

• High-resolution feedback cables.

Allen-Bradley also offers high flex-rated cable for power-track

applications. Power cables (catalog number 1326-CPB1T and 1326-

CPC1T) and commutation cables (catalog number 1326-CCUT and

1326-CECUT) are available in lengths up to 90 m (295 ft). In addition

to the features listed for standard cables, each flex-cable features

excellent minimum bend radius ratings and a superior flex cycle life.

Motor Power Cables

Connection Solutions

Several accessories are available with 460 volt 1326 cables. This

section highlights the most common application used with each

accessory, including:

• Right-angle connection.

• CE-compliant in-line connection.

• Remote in-line connection.

• Harsh environment connection.

• Double-ended bulkhead in-line connection.

Right-Angle Connection

This solution provides a low-profile right-angle connection at the motor

Linear-flex is defined as flex in one direction. The flex-rated cable is

not rated for twist-flex, which is flex in two directions. Power track

(linear-flex) cabling must not be used in twist applications.

Standard Allen-Bradley cables—1326-CCU-xxx for commutation and

1326-CPB1-xxx or 1326-CPC1-xxx for power—are tray-rated

(stationary) and should only be used for one-time flex applications.

• Power track cabling is required for applications where dynamic

linear flexing occurs. Use the following cables for these applications:

• 1326-CCUT-xxx (commutation for all motors)

• 1326-CPB1T-xxx (power for 1326AS-B3xxx and 1326AS-B4xxx motors)

• 1326-CPC1T-xxx (power for 1326AS-B6xxx and 1326AS-B8xxx motors)

Allen-Bradley high-flex cables have excellent minimum bend radius

specifications and a long flex cycle life in linear flex applications.

The cycle life of linear-flex cable is directly related to the cable’s

bend radius in the power track. Refer to the graphs on the following

page for Bend Radius vs. Cycle Life specifications.
