Chapter 4 Connect the Kinetix 3 Drive
Building Your Own Cables
• 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.
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 communication,
or other sensitive low voltage signals. This can cause system faults and
communication anomalies.
Refer to Electrical Noise Reduction
on page 23 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.
Determining Your Type of Input Power
On the following pages are examples of typical single-phase and three-phase
facility input power wired to single-phase and three-phase Kinetix 3 drives.
The Kinetix 3 drive is designed to operate in both grounded and ungrounded
environments. The grounded power configuration lets you ground your single-
phase or three-phase power at a neutral point. The ungrounded power
configuration does not have a neutral ground point.
Factory-made cables are designed to minimize EMI and are recommended over
hand-built cables to optimize system performance
