Description
The Allen-Bradley 20-HIM-A6 is an Enhanced Human Interface Module (HIM) manufactured by Rockwell Automation for the PowerFlex 7-Class drive family. As a local programming and monitoring interface, the 20-HIM-A6 provides a full numeric keypad, an enhanced LCD display, and direct drive-mount capability, enabling parameter configuration, diagnostic review, and real-time drive control without requiring a laptop or network connection.
The 20-HIM-A6 serves as the primary operator interface for drives including the PowerFlex 70, 700, 700S, 753, and 755, as well as the PowerFlex DC line. Its enhanced display offers significantly improved contrast and text legibility compared to earlier HIM revisions, and firmware version 2.002 extended compatibility to PowerFlex 7000 medium-voltage drives.
Application Scenarios
During commissioning of a PowerFlex 753 drive on a conveyor system, the technician needs to verify motor nameplate parameters, tune the speed regulator, and test directional control before connecting the drive to the plant network. The Allen-Bradley 20-HIM-A6 provides this capability directly at the drive, with a full numeric keypad that enables rapid parameter entry and a high-contrast LCD that remains readable under the harsh lighting conditions typical of industrial motor control centers.
When a drive trips unexpectedly during production, maintenance personnel can connect the 20-HIM-A6 to read the fault code, review the fault queue, and access diagnostic parameters without waiting for a controls engineer to arrive with programming software. The 20-HIM-A6 supports the DriveExplorer and DriveExecutive toolchains, allowing technicians to extract drive configuration for backup or comparison against reference settings. For facilities running mixed PowerFlex 7-Class and PowerFlex 750-Series fleets, the 20-’s backward compatibility simplifies spare parts management—one HIM model serves the entire installed base.
