Maximum Cable Lengths
Combined motor cable length for all axes on the same DC bus must not exceed
250 m (820 ft). The maximum drive-to-motor cable length for Kinetix 5500
drives and motor/actuator combinations with 2090-CxxM7DF cables is 20 m
(65.6 ft); however, you can replace the existing motor power/brake cable with a
2090-CSBM1DF or 2090-CSBM1DG single motor cable to extend the length up
to 50 m (164 ft).
Motor Power/Brake Cable Preparation
2090-CPBM7DF (series B) cables are available with 12 AWG and 10 AWG
motor-power conductor sizes. So, 14 AWG cables that are used on frame 3
drives, which are physically taller, require preparation.
Cable Preparation for Frame 1 and Frame 2 Drives
For frame 1 and frame 2 drives, the 2090-CPBM7DF (16 AWG and 14 AWG)
power conductor length, 102 mm (4.0 in.), is sufficiently long to reach the MP
connector plug and provide adequate stress relief.
The brake conductor length, 635 mm (25 in.), is much longer than necessary.
We recommend that you measure 163 mm (6.4 in.) from the edge of the cable
jacket (that is covered by heat shrink) and trim off the rest.
See Figure 56
and on page 92 for a typical installation example. For strip
lengths and torque values, refer to Table 43 on page 82.
Cable Preparation for Frame 3 Drives
2090-CPBM7DF (series B) 12 AWG and 10 AWG cables are designed for use
with Kinetix 5500 drives and do not require any modifications.
For frame 3 drives, 2090-CPBM7DF (14 AWG) cables, and 12 AWG and 10 AWG
(series A) cables, the overall length of the cable preparation area must be
increased for the motor power conductors to reach the MP connector and also
provide a proper service loop.
IMPORTANT The option to replace 2090-CPBM7DF power/brake cables with
2090-CSBM1DF/DG single cables applies to only 18 AWG and 14 AWG single
cables. 2090-CSBM1Dx-10xxxx (10 AWG/M40 connector) single cables are
not compatible with 2090-CPBM7DF-10Axxx (10 AWG/M40 connector)
power/brake cables.
When replacing your existing motor power/brake cable with a
2090-CSBM1DF/DG single motor cable, only the motor power and brake
conductors are used. Cut off the feedback conductors in the single
motor cable and reuse the existing Kinetix 2090 feedback cable.
