Appendix C Size Multi-axis Shared-bus Configurations
• Drives must be of the same power rating (catalog number).
• Shared AC configurations do not support Bulletin 2198 capacitor
modules.
• The maximum number of drives in Shared AC configurations is
restricted as described in Table 82
.
Figure 106 - Typical Shared AC Configuration
For an example shared AC installation with additional details, see Figure 2 on
page 16.
Shared DC Configurations
In a Shared DC (DC common bus) configuration, the first (leftmost) drive is
the leader drive and is the only drive that receives the AC input voltage. All
drives to the right of the leader drives are follower drives. They receive the DC
bus voltage extended from the leader drive through the shared-bus connection
system:
• For DC common-bus installations, the power rating of the leader drive
must be greater than or equal to the power rating of the follower drives.
• The leader drive is configured in the project file as Shared AC/DC.
• The follower drives are configured in the project file as Shared DC.
• Shared DC configurations support Bulletin 2198 capacitor modules.
