Allen-Bradley 20-HIM-A6 PowerFlex 700 Human Interface Module

Product Overview

The Allen-Bradley 20-HIM-A6 functions as the primary configuration and diagnostic interface for the PowerFlex 7-class series of Variable Frequency Drives (VFD). This enhanced Human Interface Module (HIM) provides full control over drive parameters, enabling rapid commissioning and real-time troubleshooting. We supply this unit as 100% Brand New and Original, ensuring your maintenance team receives a factory-sealed component for immediate deployment in critical motor control systems.

Technical Specifications

The 20-HIM-A6 utilizes the Drive Peripheral Interface (DPI) protocol to establish high-speed communication with the host drive:

Engineering Advantages

The 20-HIM-A6 optimizes the interaction between the technician and the drive hardware through several specialized design features:

• Accelerated Data Entry: The full numeric keypad eliminates the frustration of scrolling through digits. Operators type exact parameter values directly, cutting commissioning time by up to 50% compared to standard arrow-key interfaces.

• Hot-Swappable Connectivity: The DPI architecture allows you to connect or remove the HIM while the drive is powered. This enables a single 20-HIM-A6 to serve as a handheld roaming tool for an entire lineup of PowerFlex drives.

• Dynamic Language Support: The LCD display supports multiple languages and descriptive text strings, replacing cryptic error codes with actionable diagnostic information.

• Seamless Mounting Integration: The module snaps directly into the drive's cradle or mounts remotely on a cabinet door using a separate cable kit. When properly seated, it maintains a NEMA 1 rating, shielding internal contacts from standard industrial dust.

FAQs

Does the 20-HIM-A6 require an external power supply?

No. The module draws its required 140mA current directly from the host PowerFlex drive through the DPI connection cable. You do not need to wire separate power leads.

Can I use this HIM to copy parameters between two different drives?

Yes. The 20-HIM-A6 features internal memory that allows you to "Upload" a complete parameter set from one drive and "Download" it into another. This simplifies the replacement of VFD units and ensures configuration consistency across the plant floor.

Is this unit compatible with PowerFlex 750-Series drives?

While the 20-HIM-A6 primarily supports PowerFlex 70, 700, and 700H drives via the DPI port, many 750-Series drives utilize the 20-HIM-A6 through specific adapter kits. Always verify your drive's firmware version to ensure full menu compatibility.

What is the maximum cable length for remote mounting?

When mounting the 20-HIM-A6 on a cabinet door, you can extend the DPI link up to 10 meters (33 feet) using approved Allen-Bradley cables without experiencing signal degradation or data loss.
