Sizing Multi-axis Shared-bus Configurations
This appendix provides information and examples for sizing your Kinetix 5500
drive shared-bus configurations.
Shared-bus configurations include the following types:
• Shared AC
• Shared DC (common bus)
• Shared AC/DC
• Shared AC/DC Hybrid
These restrictions apply to all shared-bus configurations:
• Shared-bus configurations must use the shared-bus connection system.
• Single-phase drive operation is not supported.
• Shared AC/DC and shared AC/DC hybrid configurations result in a
derating of 30% of the total converter power available.
• The zero-stack tabs and cutouts must be engaged from drive-to-drive.
Systems cannot start in one cabinet and end in another.
• Program drives for the same converter AC input voltage.
Shared-bus Configurations Shared AC configurations are configured as Standalone in the project file and do
not share these restrictions that apply to multi-axis shared-bus configurations:
• All drives in a bus-sharing group must be configured with the same bus
power-sharing group number in the Logix Designer application.
• The maximum number of drives in any bus power-sharing group cannot
exceed eight.
