Shared DC Common-bus Configurations
In this multi-axis example, the common-bus leader (sourcing) drive receives
three-phase AC input power and supplies DC power to common-bus follower
(sinking) drives. The common-bus leader-drive power rating is greater than or
equal to the power rating of each follower drive.

IMPORTANT In shared DC common-bus configurations, the leader drive power rating
must be greater than or equal to the power rating of the follower drives.
