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.

(1) Requires the 2198-H2DCK Hiperface-to-DSL feedback converter kit. LDAT-Series linear thrusters and MP-Series (200V-class) motors
and actuators require the 2198-H2DCK (series B or later) converter kit.

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.
