Rockwell Kinetix 6000 Integrated Axis Module

Rockwell Kinetix 6000 Integrated Axis Module

Executive Summary

The Kinetix 6000 Integrated Axis Module (IAM) is a family of multi-axis servo drive inverter modules from Rockwell Automation (Allen-Bradley) designed to control servo motors in a common DC-bus, multi-drive configuration. These modules mount on a shared power rail alongside a system power supply (converter) and control interface modules, delivering compact, high-performance motion control tightly integrated with the Logix platform (ControlLogix, CompactLogix). The Kinetix 6000 series supports SERCOS interface and/or EtherNet/IP-based control, depending on the bridge/communication module used, and provides integrated safety options such as Safe Torque-Off (STO). As of Dec 31, 2023, Rockwell has announced that Kinetix 6000 Axis Modules are discontinued and no longer available for sale, but they remain in wide installed base globally.

Positioning and Architecture

Product family: Kinetix 6000 Multi-axis Servo Drives (Bulletin 2094).

Role: Integrated Axis Module (IAM) — the inverter stage that converts DC bus power to controlled AC power for one servo motor axis. Multiple IAMs share one DC bus supplied by a system power supply/converter module.

Typical configuration:

Line Filter / Line Interface Module (if required)

Power Supply Module (converts AC to DC bus)

Control Interface/Bridge Module (SERCOS or EtherNet/IP)

Multiple Axis Modules (IAMs) or Axis Modules (AMs) on the same power rail (e.g., 2094-BMxx, 2094-AMxx, 2094-BC07-M0x-S).

Integrated safety: Many IAMs offer Safe Torque-Off (STO) functionality (“-S” suffix), enabling compliance with PLe/SIL 3 requirements without external contactors for safety-related torque removal.

Key Features

High power density in a compact, modular form factor that slides onto the 2094 Power Rail (for Kinetix 6000/6000M/6200/6500).

Common DC bus architecture reduces component count, simplifies wiring, and enables energy sharing between axes (including shared regenerative/shunting capability when used with shunt modules).

Tight integration with the Logix architecture:

Configuration, programming, and maintenance via Studio 5000 / RSLogix 5000.

SERCOS fiber-ring or EtherNet/IP connectivity for real-time motion control (depending on the bridge module).

Integrated Safe Torque-Off (STO) on selected models (suffix “-S”) simplifies safety circuits and reduces cabinet space.

Support for a broad range of Allen-Bradley servo motors (MP-Series, TL-Series, HPK, etc.), with multiple feedback types supported via compatible motor/feedback options and bridge modules.

Peak-enhanced operation modes available on certain axis modules for higher short-term torque output when configured according to user manuals.

Voltage Classes and Current Ratings

The Kinetix 6000 Integrated Axis Modules are offered in two main voltage classes:

200–230V class (low-voltage) Axis Modules (commonly cataloged as 2094-AMxx, 2094-BCxx-M0x for certain IAM/AM variants). Typical inverter ratings include around 9 A and 15 A outputs for 200/230 V systems.

400–460V class (high-voltage) Axis Modules (commonly cataloged as 2094-BMxx and 2094-BC07-M0x). Typical inverter ratings include 9 A, 15 A, 28 A, and 48 A outputs for 400/460 V systems.

Examples of per-axis continuous current capability:

2094-BM01-S: 9 A inverter, 400/460 V class, with STO.

2094-BM02-S: 15 A inverter, 400/460 V class, with STO.

2094-BM03-S: 28 A inverter, 400/460 V class, with STO.

2094-BM05-S: 48 A inverter, 400/460 V class, with STO.

2094-BC07-M05-S: 67.7 A continuous output current to bus at 360–480 V input; 49 A inverter (integrated axis module).

Integrated Axis Module vs Axis Module (IAM vs AM)

Integrated Axis Module (IAM): A module that combines functions in a more integrated package, used in Kinetix 6000/6000M/6200/6500 systems. IAMs are designated by catalog numbers such as 2094-xCxx-Mxx-S and 2094-BCxx-M0x-S. They may include both converter and inverter stages or are optimized as integrated building blocks in a multi-axis system.

Axis Module (AM): A per-axis inverter module that is part of the Kinetix 6000 multi-axis system; examples include 2094-AM01, 2094-AM02, 2094-AM03, 2094-AM05 for 200/230 V and 2094-BM01/BM02/BM03/BM05 for 400/460 V, often with or without STO (suffix -S).
