Chapter 2 Install the Kinetix 3 Drive System
•
Segregate input power wiring and motor power cables from control wiring
and motor feedback cables. Use shielded cable for power wiring and
provide a grounded 360° clamp termination.
•
Use high-frequency (HF) bonding techniques to connect the enclosure,
machine frame, and motor housing, and to provide a low-impedance
return path for high-frequency (HF) energy and reduce electrical noise.
•
Use 2090 series motor feedback cables or use connector kits and properly
terminate the feedback cable shield. Drive-to-motor feedback cables must
not exceed 30 m (98.4 ft). Drive-to-motor power cables must not exceed
30 m (98.4 ft).
Refer to the System Design for Control of Electrical Noise Reference Manual,
publication
GMC-RM001 , to better understand the concept of electrical noise
reduction.
Fuse Selection
The Kinetix 3 drives use internal solid-state motor short-circuit protection and,
when protected by suitable branch circuit protection, are rated for use on a
circuit capable of delivering up to 100,000 A. Fuses or circuit breakers, with
adequate withstand and interrupt ratings, as defined in NEC or applicable local
codes, are permitted.
Refer to Fuse/Contactor Specifications on page 19 for recommended fuses.
Refer to Kinetix Servo Drives Specifications Technical Data for input current and
inrush current specifications for your Kinetix 3 drive.
IMPORTANT
System performance was tested at these cable length specifications. These
limitations are also a CE requirement.
