Allen-Bradley 20-HIM-A6/A PowerFlex 7-Class Enhanced HIM – Full Numeric Keypad, Dynamic Soft Keys, NEMA Type 1

Product Overview
The 20-HIM-A6/A is an enhanced human interface module (HIM) designed by Allen-Bradley, a brand of Rockwell Automation, specifically for the PowerFlex 7-Class and Architecture-Class AC drives. As the local operator terminal mounted directly in the drive’s HIM bezel (Port 1), the 20-HIM-A6/A replaces the discontinued 20-HIM-A3 as the factory-designated direct substitute, delivering a substantially upgraded user experience for commissioning, parameter configuration, real-time monitoring, fault diagnosis and drive control. Within the PowerFlex HIM product hierarchy, the 20-HIM-A6/A represents the NEMA Type 1 local/ handheld variant of the enhanced HIM family, with its sibling 20-HIM-C6S serving remote-mount NEMA 4X/12 applications.
The core strength of the 20-HIM-A6/A lies in its combination of a full-numeric keypad with fully-integrated navigation keys, a dynamic backlit LCD, and context-sensitive soft keys that change function based on the active screen. Unlike basic HIMs that rely on tedious scrolling, the 20-HIM-A6/A allows engineers to enter parameters directly via numeric input or navigate intuitively through redesigned menu structures. The module communicates with the host drive over the Drive Peripheral Interface (DPI) protocol at 125 kbps or 500 kbps, drawing its 12V DC power (140 mA) directly from the drive—no external power supply required. A distinctive flashing LCD feature provides immediate visual alarm indication when faults or abnormal conditions occur, enabling operators to detect issues from a distance without reading tiny text.
Compatible with the entire PowerFlex 7-Class ecosystem—including PowerFlex 70, 700, 700H, 700S, 700L, 700AFE, 7000, 753, 755, PowerFlex Digital DC drives, SMC Flex and SMC-50 smart motor controllers—the 20-HIM-A6/A has become the de facto standard for local drive interaction across Rockwell Automation’s motion control portfolio. Its multi-language support spanning English, French, German, Spanish, Italian, Portuguese, Chinese and Japanese, combined with customizable drive monitoring screens and simplified custom name assignment (e.g., “Pump 1”), makes the 20-HIM-A6/A an indispensable tool for global industrial operations where clarity, speed and reliability are paramount.

Main Features and Advantages

The 20-HIM-A6/A redefines local drive operation through a thoughtfully engineered blend of hardware and software enhancements. At the heart of the 20-HIM-A6/A is its full-numeric keypad with fully-integrated navigation capability. Unlike basic HIMs that force operators to scroll through menus to find parameter numbers, the 20-HIM-A6/A supports both the “Individual Screen Entry Method” and the much faster “Direct Numeric Entry Method.” Engineers can type a parameter number directly, jump to the relevant screen, and edit the value—transforming what used to be a minutes-long exercise into a few seconds of keystrokes. The improved tactile feel of the keypad further reduces data-entry errors, a critical advantage in noisy industrial environments where precision matters.Dynamic soft keys for intuitive operation:The 20-HIM-A6/A introduces dynamic soft keys that change their function and on-screen label based on the active display or data-entry mode. This context-sensitive design reduces the total number of physical keys required while simultaneously simplifying operation—the HIM presents exactly the options the operator needs at any given moment. Combined with redesigned, more intuitive menu structures, the 20-HIM-A6/A dramatically increases HIM operating efficiency, shortening the learning curve for new operators and accelerating commissioning for experienced engineers.Flashing LCD for instant fault visibility:One of the most practical innovations of the 20-HIM-A6/A is its flashing LCD screen feature. When the host drive detects a fault or alarm condition, the 20-HIM-A6/A display begins to flash, immediately drawing the operator’s attention even from across the room. The full-text LCD renders fault descriptions in plain language—no more decoding numeric fault codes against a manual. Operators can read the fault cause, view the drive status at the moment of failure, and execute a local reset without connecting a laptop, drastically reducing mean-time-to-recovery on the factory floor.Customizable monitoring and simplified naming:The 20-HIM-A6/A allows users to assign custom names to drives and peripherals (e.g., “Pump 1”, “Conveyor 2”) and to configure customizable drive monitoring items that appear either as a consolidated list on the process screen or as individual dedicated screens. This personalization means operators see exactly the parameters they care about—motor current, torque, frequency, power—without wading through irrelevant data. For facilities running diverse PowerFlex fleets, standardizing on the 20-HIM-A6/A simplifies both spare parts management and operator training, because a single HIM model works across PowerFlex 70, 700, 753, 755, SMC Flex and SMC-50 alike.
