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 6000 leader IAM can operate with non-Kinetix 6000
follower drives, as can the Kinetix 6000 follower IAM 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 IAMs.
Typical DC 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 6000 drive firmware v1.85 and RSLogix 5000
software v15 or later, for dc common bus power configurations.
IMPORTANT
Any non-Kinetix 6000 common bus leader 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.
