Allen-Bradley 20-HIM-A6 PowerFlex Architecture Class HIM

The Allen-Bradley 20-HIM-A6 (20-HIM-A6 PowerFlex Architecture Class Human Interface Module) provides local operator interface functionality for PowerFlex drives and related Rockwell Automation motion control products. The module integrates parameter configuration, diagnostics, monitoring, and drive commissioning capabilities through a multi-line LCD display and dedicated keypad interface.

Hardware Specifications

Drive Configuration and Parameter Management

The 20-HIM-A6 serves as the primary local operator interface for PowerFlex drive systems. Through the integrated LCD display and keypad, users can access operating status, monitor process variables, modify drive parameters, and review diagnostic information.

The display supports multi-language text presentation and incorporates flashing alarm and fault notification functions to assist operators during troubleshooting and maintenance activities.

Using the DPI communication interface, the HIM exchanges information directly with the connected drive and provides access to configuration functions without requiring a separate programming workstation.

CopyCat Memory and Drive Commissioning

The module incorporates non-volatile memory supporting Rockwell Automation CopyCat functionality. Parameter files can be uploaded, stored, and downloaded to compatible drives for simplified commissioning and replacement procedures.

Storage capacity includes:

• Up to 50 individual parameter files

• Up to 5 multi-device parameter files

Additional features include:

• Real-time clock configuration

• Password-protected parameter access

• Drive diagnostics and fault review

• Multi-language operator interface support

These functions assist in reducing commissioning time and maintaining configuration consistency across multiple drive installations.

Frequently Asked Questions

Q: Is the 20-HIM-A6 a standalone HMI?
A: No. The module receives power from a compatible drive and functions as a local operator interface for supported PowerFlex products.

Q: Can parameters be copied between drives?
A: Yes. The integrated CopyCat feature allows parameter upload, storage, and download between compatible drives.

Q: Does the module support multiple languages?
A: Yes. The display firmware includes multi-language text support for operation and diagnostics.

Field Installation Guidelines

• Verify compatibility with the installed PowerFlex drive series before installation.

• Ensure the DPI communication connection is fully seated before energizing the drive.

• Mount the HIM securely when used as a panel-mounted operator interface.

• Avoid exposure to excessive moisture or corrosive atmospheres beyond the specified environmental ratings.

• Verify parameter backup before replacing or commissioning a drive.

• Use approved communication cables when operating the HIM remotely.

• Perform communication verification and functional testing after installation.
