Chapter 2 Install the Kinetix 350 Drive System
• 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 power and
feedback cables must not exceed 20 m (65.6 ft).
See the System Design for Control of Electrical Noise Reference Manual,
publication
GMC-RM001 , to understand the concept of electrical noise
reduction better.
Circuit Breaker/Fuse Selection
The Kinetix 350 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) and 65,000 A (circuit
breakers).
Make sure the selected components are properly coordinated and meet
acceptable codes including any requirements for branch circuit protection.
Evaluation of the short-circuit available current is critical and must be kept
below the short-circuit current rating of the circuit breaker.
See the Kinetix Servo Drives Specifications Technical Data, publication
KNX-TD003 for input current and inrush current specifications for your
Kinetix 350 drive.
See Fuse and Circuit Breaker (CB) Specifications on page 19 for
recommended circuit breakers and fuses.
IMPORTANT System performance was tested at these cable length specifications. These
limitations are also a CE requirement.
IMPORTANT Do not use circuit protection devices on the output of an AC drive as an
isolating disconnect switch or motor overload device. These devices are
designed to operate on sine wave voltage and the drive's PWM waveform
does not allow it to operate properly. As a result, damage to the device
occurs.
