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 precharge,
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 57 - 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 43 - 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 precharge is required to add an additional external precharge circuit
before connecting to any Kinetix 6000 common-bus follower IAM module.
