DC Common Bus
Configurations When the IAM module is used in a DC common-bus configuration, the IAM
module is known as a leader IAM or follower IAM module. The IAM (non-
common bus) and leader IAM module have identical three-phase input power
connections. The leader IAM module 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 IAM
modules do not have three-phase input power connections, but have DC bus
connections from a leader IAM module.
Table 56 - IAM Module Terminology and Use
The Kinetix 6000 leader IAM module can operate with non-Kinetix 6000
follower drives, as can the Kinetix 6000 follower IAM module operate with non-
Kinetix 6000 common-bus leader drives. However, non-Kinetix 6000 leader and
follower drives must meet the same functional requirements as the Kinetix 6000
leader and follower IAM modules.
Figure 42 - Typical DC Common-bus Configuration
This Module 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 module.
Wired in Common-bus mode.
Follower IAM
Without three-phase input power, but has DC common-bus
connections from a leader IAM module. Wired in Common-bus mode and configured by
using the Logix Designer application.
IMPORTANT Use Kinetix 6000 drive firmware revision 1.85 and the Logix Designer
Application or RSLogix 5000 software, version 15 or later, for common-bus
power configurations.
IMPORTANT Any non-Kinetix 6000 common-bus leader IAM module that does not provide
pre-charge is required to add an additional external pre-charge circuit before
connecting to any Kinetix 6000 common-bus follower IAM module.
