What It Does (Simple Explanation)

This module is the core power unit of a Kinetix 6000 rack system:

1. AC 3-phase power enters the module
2. It converts AC → DC bus (~650V)
3. The DC bus is shared with all axis modules
4. Each axis module drives its own servo motor

Key Features

• Integrated converter + system control function
• Shared DC bus architecture for multi-axis systems
• Supports high-performance servo motion control
• Safe Torque Off (STO) safety function
• High efficiency industrial drive design
• Modular expansion with multiple axis modules

Advantages

• Reduces wiring complexity (single DC bus system)
• Enables synchronized multi-axis motion
• High power capacity for industrial machines
• Strong integration with Rockwell PLC systems
• Stable performance for continuous operation

Applications

• Packaging machines
• Printing equipment
• Robotics systems
• CNC and precision motion systems
• Multi-axis assembly lines

Important Precautions

•  
• Must be used with:
  • Kinetix 6000 power rail system
  • Axis modules (BM series)
  • SERCOS / Logix motion controller
• High voltage hazard:
  • DC bus can remain charged after power-off
• Incorrect system matching may cause:
  • DC bus faults
  • axis communication errors
  • full system shutdown
• Proper cooling and rack configuration required
