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 87
.
