Product Overview
The Allen-Bradley 20-HIM-A6 is an enhanced Human Interface Module (HIM) used with PowerFlex AC drives. It provides a local or handheld interface for configuring, monitoring, and controlling drive parameters.
It is commonly used with PowerFlex 70, 700, 700H, 700S, 753, and 755 series drives, offering a more advanced user interface compared to earlier HIM models such as the 20-HIM-A3.

Function and Working Principle
The 20-HIM-A6 connects to the drive via the DPI communication port and serves as a local control terminal. It allows users to:
- View and edit drive parameters
- Start, stop, and control motor operation (depending on access level)
- Display real-time status, alarms, and faults
- Transfer parameter sets between drives (copy function)
Compared with older HIM models, it offers improved navigation and display clarity for fault conditions.
Role in Industrial Systems
This module is used for:
- Drive commissioning and setup
- Maintenance and troubleshooting
- On-site manual operation
- Parameter backup and duplication
- Fault diagnostics and system monitoring
It is especially useful in environments where direct PLC access is limited.
Industrial Applications
- Conveyor systems
- Pumps and fans
- HVAC systems
- Packaging machinery
- General industrial motor control systems
Installation Notes
- Mounts directly on compatible PowerFlex drives or remote bezel kits
- Connects via DPI port (Drive Peripheral Interface)
- Can be used as handheld or panel-mounted interface
- Must match drive firmware compatibility
Compatible Equipment
- PowerFlex 70 / 700 / 700H / 700S
- PowerFlex 753 / 755
- Other DPI-based Rockwell drive platforms
Key Advantages
- Enhanced LCD visibility and navigation
- Full keypad for precise parameter entry
- Flexible handheld or mounted operation
- Strong compatibility across PowerFlex 7-class drives
- Improved diagnostics over earlier HIM versions
Comparison Note (A3 vs A6)
Compared to the 20-HIM-A3, the A6 typically provides:
- Improved display visibility (faults/alarms more noticeable)
- Enhanced navigation interface
- More intuitive parameter access
- Better usability in commissioning and diagnostics tasks
Limitations
- Legacy accessory (not Ethernet-based)
- Limited functionality compared to modern HMI panels
- Depends entirely on DPI drive architecture
Conclusion
The Allen-Bradley 20-HIM-A6 PowerFlex Human Interface Module is an enhanced local control and configuration device for PowerFlex drives.
It improves usability, diagnostics, and commissioning efficiency, making it a widely used interface in industrial drive systems, especially where on-site control and troubleshooting are required.
