1.2.2.4.4. Power Supply/Accessories – AC/DC Power Sharing Systems (Kinetix 5500 drives)

If your drive family is Kinetix 5500, you must define a valid power sharing
configuration and then configure a shunt and capacitor, or specify if no shunt or
capacitor are required.

DC Sharing

Use this option for shared AC/DC or common bus configuration. The following restrictions are imposed on the
number of drives allowed in common bus, or shared AC/DC configuration, based on the converter capacity and/or
connectors:

Single phase operation is not allowed.

The bus master drive or drives with an AC connection should have the same power rating (catalog number).

The bus master drive or drives should always have a rating equal to, or greater than, the followers.

The number of bus master drives cannot exceed the following rule: Frame 3 = two drives; Frame 2 = four drives;

Frame 1 = eight drives.

The number of follower drives is driven by the frame of the master drive or drives, and cannot exceed this rule:

Frame 1 drive = only four more bus followers can be added; Frame 2 drive = only six more bus followers can be
added.

Converter power output should be reduced by 30% of the sum of the individual converter power capacities of

drives configured for shared AC/DC.

The maximum number of drives in a bus power sharing group is eight drives.

AC Sharing Only

3-phase AC input power can be shared among drives with the same power rating. No DC bus connections are
allowed in this configuration. AC power sharing allows you to minimize the system components, such as circuit
breakers and fuses. The following limitations apply when drives are configured for sharing AC input power:

Single-phase operation is not allowed.

All drives must be configured for the same converter voltage rating.

Drives with the same power rating (catalog number) can be used for this configuration.

The maximum number of drives that can be configured for shared AC operation is limited by the amp capacity of

the AC input connector. The following rules apply: Frame 1 drives can share AC with up to five drives of the same
rating; Frame 2 drives can share AC with up to three drives of the same rating; Frame 3 drives can share AC with
up to two drives of the same rating.
