What it actually is

This is not a standalone VFD or PLC module.

It is one axis module inside a Kinetix 6000 rack system, meaning:

• It mounts on a shared power rail
• Works together with:
  • line/power supply module
  • other axis modules (BM01, BM02, BM03, etc.)
  • shunt module / safety components
• Each BM module controls one servo motor axis

Function (Simple Explanation)

PLC motion controller
→ sends motion commands (SERCOS)
→ 2094-BM03-S axis module
→ outputs controlled 3-phase power
→ drives servo motor (position/speed/torque control)

So it acts as a high-power precision motor controller, not a general inverter.

System Role

• Controls one servo axis in a multi-axis machine
• Shares energy via DC bus with other axes
• Handles fast acceleration/deceleration loads
• Works only in a full Kinetix 6000 architecture

Typical Applications

• CNC machines
• Robotics systems
• Packaging and printing machines
• High-speed synchronized production lines
• Multi-axis automation equipment

Key Features

• Multi-axis modular design (scalable system)
• High power density (~13.5 kW class)
• STO (Safe Torque Off) safety support
• High dynamic response for fast motion control
• Integrated into Rockwell Logix motion system
• Efficient shared DC bus energy system

Important Notes

• Discontinued product (Kinetix 6000 platform is phased out)
• Requires full system (rail, power supply, controller)
• Cannot operate standalone
• Replacement platforms: Kinetix 5700 / 5500 systems
• Requires Logix motion configuration (Studio 5000)
