Sizing Multi-axis Shared-bus Configurations
Shared AC Configurations
In shared AC configurations, the first (leftmost) drive receives AC input voltage.
The shared-bus connection system extends the AC bus to all downstream drives:
•
All drives are configured in the project file as Standalone drives.
•
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 85 - Shared AC Panel Layout
Figure 99 - Typical Shared AC Configuration
For an example shared AC installation with additional details, refer to
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 a Shared AC/DC drive.
•
The follower drives are configured in the project file as Shared DC drives.
•
Shared DC configurations support Bulletin 2198 capacitor modules.
