Building Your Own Cables

Factory made cables are designed to minimize EMI and are
IMPORTANT
recommended over hand-built cables to ensure system
performance.
When building your own cables, follow the guidelines listed below.
•
Connect the cable shield to the connector shells on both ends of the cable
for a complete 360° connection.
•
Use a twisted pair cable whenever possible, twisting differential signals
with each other, and single-ended signals with the appropriate ground
return.
Refer to Appendix C for drive connector kit catalog numbers.

Routing Power and Signal Wiring

Be aware that 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, communications, or other
sensitive low voltage signals. This can cause system faults and communication
problems.
Refer to Chapter 1 for examples of routing high and low voltage cables in
wireways. Refer to System Design for Control of Electrical Noise Reference Manual
(publication GMC-RM001x-EN-P) for more information.
