Recommended Cables
The Motor Power Cable Compatibility table on page 65 and Motor Feedback
Cables for Specific Motor/Feedback Combinations table on page 70 show the
cables Rockwell Automation® recommends that you use with the Kinetix® 350
drive.
If it is necessary for you to build or modify your own cable, follow these
guidelines:
•
Connect the cable shield to the connector shells on both ends of the
cable with a complete 360° connection.
•
Use twisted-pair cable whenever possible. Twist differential signals with
each other and twist single-ended signals with the appropriate ground
return.
See the Kinetix Motion Control Selection Guide, publication
KNX-SG001 , for low-profile connector kit, drive-end (mating) connector kit,
and motor-end connector kit catalog numbers.
Route Power and Signal Wiring
When you route power and signal wiring on a machine or system, radiated
noise from nearby relays, transformers, and other electronic drives can be
induced into motor or encoder feedback signals, input/output
communication, or other sensitive low voltage signals. Radiated noise can cause
system faults and communication anomalies.
See Electrical Noise Reduction on page 24 for examples of routing high and
low voltage cables in wireways. See the System Design for Control of Electrical
Noise Reference Manual, publication
GMC-RM001 , for more information.
Determine the Input Power
Configuration This section contains examples of typical single-phase and three-phase facility
input power that is wired to single-phase and three-phase Kinetix 350 drives.
The grounded power configuration lets you ground your single-phase or three-
phase power at a neutral point. Match your secondary to one of the examples
and be certain to include the grounded neutral connection. See
Table 68 on
page 152 for leakage currents.
IMPORTANT Factory-made cables are designed to minimize EMI and are recommended
over hand-built cables to optimize system performance.
