Allen-Bradley 20-HIM-A6-A Human Interface
The Allen-Bradley 20-HIM-A6-A serves as the primary 20-HIM-A6-A Human Interface Module utilized to execute local parameter programming, drive diagnostic monitoring, and real-time operational control across PowerFlex drive platforms. Powering directly from the host drive via a 12 VDC connection, this panel- or drive-mounted interface utilizes the Drive Peripheral Interface (DPI) protocol at selectable data rates of 125 Kbps or 500 Kbps to enable high-speed configuration and operator command execution.

Deterministic Backplane Bus Communications and Drive Control Execution
The 20-HIM-A6-A interfaces with the internal drive backplane bus through a dedicated DPI port connector to achieve deterministic control signal transmission. Its firmware flash compatibility ensures synchronized parameter uploading, downloading, and dynamic menu navigation across PowerFlex 7-Class and 750-Series AC drives. The physical interface hardware scales across high-density drive control architectures without imposing additional bus communication latencies on real-time speed, torque, or safety loop processing.
Frequently Asked Questions
Q: Does the 20-HIM-A6-A module require an external power supply when configured for remote door mounting?
A: No, the module receives its required operating power (140 mA at 12 VDC) directly from the host PowerFlex drive through the DPI communication interface cable.
Q: What happens to drive operations if the 20-HIM-A6-A is disconnected during motor execution?
A: Drive response depends on parameter settings in the host control logic; if configured for HIM loss detection, the drive executes an immediate fault or speed hold to maintain system safety upon signal interruption.
Field Installation Guidelines
- Power down the host PowerFlex drive and verify zero-voltage state on the main DC bus before inserting or removing the HIM module from the drive bay connection port.
- For remote door mounting configurations, secure the NEMA 1 bezel assembly into the cut panel opening and verify the rubber sealing gasket forms a uniform flush seal.
- Route the shielded DPI cable away from high-voltage AC motor leads and input power wiring to mitigate electro-magnetic interference (EMI) on communication lines.
- Ensure the cable connector screws are fully tightened into the DPI port to preserve physical ground bonding and establish reliable electrical contact.
