majority of applications. National Electrical Code, local
electrical codes, special operating temperatures, duty cycles, or

Building Your Own Cables

Factory-made cables are designed to minimize EMI and are
IMPORTANT
recommended over hand-built cables to optimize system
performance.
•
Connect the cable shield to the connector shells on both ends of
the cable with a complete 360° connection.
•
Use a twisted pair cable whenever possible. Twist differential
signals with each other and twist single-ended signals with the
appropriate ground return.
Refer to the Kinetix Motion Control Selection Guide, publication
GMC-SG001 for low profile connector kit, drive-end (mating)
connector kit, and motor-end 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
signals, input/output communications, or other sensitive low voltage
signals. This can cause system faults and communication problems.
Refer to Minimizing Electrical Noise on page 27 for examples of
routing high and low voltage cables in wireways. Refer to the System
Design for Control of Electrical Noise Reference Manual, publication
GMC-RM001, for more information.
