DC Common Bus
Configurations

When an integrated axis module (IAM) is used in a dc common bus
configuration, the IAM is known as a leader IAM or follower IAM. The IAM
(non-common bus) and leader IAM have identical three-phase input power
connections. The leader IAM is responsible for discharging the dc bus, and for
providing common bus follower drives with dc bus pre-charge, bus regulation,
phase-loss detection, and ground fault detection. Follower IAMs do not have
three-phase input power connections, but have dc bus connections from a
leader IAM.

IAM Terminology and Use

The Kinetix 2000 leader IAM can operate with non-Kinetix 2000 follower
drives, as can the Kinetix 2000 follower IAM operate with non-Kinetix 2000
common bus leader drives. However, non-Kinetix 2000 leader and follower
drives must meet the same functional requirements as the Kinetix 2000 leader
and follower IAMs.

Typical Common Bus Configuration

This IAM

Is Wired

And is

IAM

With three-phase input power.

Not wired in common bus mode.

Leader IAM

With three-phase input power, but has
dc common bus connections to a
follower IAM.

Wired in common bus mode.

Follower IAM

Without three-phase input power, but
has dc common bus connections from
a leader IAM.

Wired in common bus mode and
configured using RSLogix 5000
software.

IMPORTANT

Use Kinetix 2000 drive firmware v1.95.18 and RSLogix 5000 software,
version 16 or later, for common dc bus power configurations.

IMPORTANT

Any non-Kinetix 2000 common bus leader that does not provide
pre-charge is required to add an additional external pre-charge circuit
before connecting to any Kinetix 2000 common bus follower IAM.
