Chapter 2 Planning the Kinetix 6000 Drive System Installation
System Design Guidelines Use the information in this section when designing your enclosure and planning
to mount your system components on the panel.
For on-line product selection and system configuration tools, including
AutoCAD (DXF) drawings of the product, refer to

System Mounting Requirements
•
To comply with UL and CE requirements, the Kinetix 6000 drive system
must be enclosed in a grounded conductive enclosure offering protection
as defined in standard EN 60529 (IEC 529) to IP2X such that they are
not accessible to an operator or unskilled person. A NEMA 4X enclosure
exceeds these requirements providing protection to IP66.
•
The panel you install inside the enclosure for mounting your system
components must be on a flat, rigid, vertical surface that won’t be subjected
to shock, vibration, moisture, oil mist, dust, or corrosive vapors.
•
Size the drive enclosure so as not to exceed the maximum ambient
temperature rating. Consider heat dissipation specifications for all drive
components.
•
Combined motor power cable length for all axes on the same DC bus must
not exceed 240 m (787 ft) with 460V systems or 160 m (525 ft) with 230V
systems. Drive-to-motor power cables must not exceed 90 m (295.5 ft).
• 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 modules,
enclosure, machine frame, and motor housing, and to provide a
low-impedance return path for high-frequency (HF) energy and reduce
electrical noise.
Refer to the System Design for Control of Electrical Noise Reference Manual,
publication
GMC-RM001 , to better understand the concept of electrical noise
reduction.
IMPORTANT
System performance was tested at these cable length
specifications. These limitations also apply when meeting CE
requirements.
