A-B 2094-BC02-M02-S Servo Drive Axis Module

 

The 2094-BC02-M02-S is a Kinetix 6000 Integrated Axis Module (IAM / axis drive module) used in Rockwell’s multi-axis shared DC bus servo system. It is designed to control one servo motor axis inside a modular motion control rack.

Product Overview

• Brand: Allen-Bradley (Rockwell Automation)
• Series: Kinetix 6000
• Part Number: 2094-BC02-M02-S
• Type: Integrated Axis Module / Servo Drive Axis Module
• System: Multi-axis shared DC bus servo system
• Function: Servo motor power + motion control output stage

Key Technical Data

• Input voltage: 360–480V AC (3-phase class)
• Power rating: ~15 kW converter class
• Inverter current: ~15 A
• Continuous output current: ~22.6 A
• Efficiency: up to ~97%
• Safety function: Safe Torque Off (STO)
• DC bus: shared ~650V DC architecture

What it actually does

This module is not a PLC and not a standalone VFD.

It works like this:

PLC (ControlLogix / CompactLogix motion controller)
→ sends motion commands (SERCOS network)
→ 2094-BC02-M02-S axis module
→ converts DC bus power into controlled 3-phase output
→ drives one servo motor (position / speed / torque control)

So it is a high-precision servo amplifier for one axis.

System Role

Inside a Kinetix 6000 rack system:

• Shares DC power with other axis modules
• Works with line interface / power supply module
• Each BC/BM module = one axis control channel
• Supports synchronized multi-axis motion

Typical Applications

• CNC machinery
• Multi-axis robotics
• Packaging machines
• Printing and labeling systems
• High-speed synchronized production lines
• Industrial motion control systems

Key Features

• Modular multi-axis architecture (expandable system)
• High efficiency shared DC bus design
• Integrated Safe Torque Off (STO) safety
• High dynamic response for fast motion
• Designed for precise synchronized positioning
• Industrial-grade continuous operation

Important Notes

• This is a legacy Kinetix 6000 platform product (discontinued family)
• Cannot operate alone — requires full rack system (power rail + controller)
• Requires Logix motion configuration (Studio 5000 / RSLogix 5000)
• Replacement platforms: Kinetix 5500 / 5700 series

Precautions

• High-voltage DC bus (~650V) → serious electrical hazard
• Must match correct power rail and system components
• Incorrect module placement can fault entire axis group
• Firmware/version compatibility is critical
• Not interchangeable with PowerFlex VFDs or PLC modules
