DC Common Bus
Configurations When the IAM power 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 47 - IAM Module Terminology and Use
The Bulletin 2094 leader IAM power module can operate with non-Bulletin
2094 follower drives, as can the Bulletin 2094 follower IAM module operate with
non-Bulletin 2094 common-bus leader drives. However, non-Bulletin 2094
leader and follower drives must meet the same functional requirements as the
Bulletin 2094 leader and follower IAM modules.
Figure 50 - 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 RSLogix 5000 software.
IMPORTANT Any non-Bulletin 2094 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 Bulletin 2094 common-bus follower IAM module.
