Shared AC/DC Configurations
In a shared AC/DC configuration, the first (leftmost) drive receives AC input
voltage. The shared-bus connection system extends the AC and DC bus to all
downstream drives:
• All drives are configured in the project file as Shared AC/DC drives.
• Drives must be of the same power rating (catalog number).
• Shared AC/DC configurations support Bulletin 2198 capacitor modules
• Total available converter power is derated by 30%.
• The maximum number of drives configured as Shared AC/DC is
described in Table 84
.

For an example shared AC/DC installation with additional details, see Figure 3
on page 17.
