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-CECUT-xxx (commutation for -Mx and -Sx motors)
•
1326-CCUT-xxx (commutation for all resolver motors)
•
1326-CPB1T-xxx (power for 1326AB-B4/B5xxxx and 1326AS-B3/B4xxxx motors)
•
1326-CPC1T-xxx (power for 1326AB-B7xxxx and 1326AS-B6/B8xxxx 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 Figure 8.56 and Figure 8.57 on the following page for bend radius vs. cycle life
specifications.
